I will now turn the call over to Baidu's CEO, Robin Li.
Robin Li - Chairman and CEO
Hello everyone and thank you for joining today's call.
We are proud of the substantial progress we made in all our key strategic areas in the third quarter.
Through continued improvements to our core products, we further cemented Baidu's place at the center of China's internet.
Our upward momentum on mobile front was especially encouraging.
Mobile revenue continued to accelerate, outpacing Mobile Search traffic growth and we have introduced an exciting new paradigm in app distribution which I will talk about more in a moment.
Baidu believes in opening up the endless possibilities of the internet to as many users and developers and customers as we can.
We are building an open and accessible ecosystem that fosters innovation and we strive to connect a growing number of developers to users across multiple channels.
This quarter we made great strides toward that goal.
At Baidu World 2012, we announced our seven weapons for developers, offering free infrastructure, tools and resources to the developer community to create a vibrant app ecosystem.
This year, in the third quarter, we made the Baidu ecosystem even more compelling by significantly strengthening our app distribution capability, particularly in native apps.
Our acquisition of 91 Wireless, which closed on October 1st, significantly bolsters Baidu's position in the vital area of app distribution.
With this combination of 91 Wireless and Baidu's mobile assistant app store and other distribution channels, Baidu is the number one app distribution channel in China, distributing 80 million apps on a daily basis.
By working closely with developers and applying Baidu's unrivalled search capabilities to our vast combined library of apps, we are creating a new app search experience.
Users looking for an app will no longer need to include a specific name, term, or text in an app's description.
Baidu will make any text or function within the whole app searchable and recommend the most relevant apps for a given query.
We have laid out a clear plan for integrating 91 Wireless.
We are looking to leverage the distribution power of Baidu and 91 Wireless platforms to have them cross-promote each other's products.
We look forward to integrating the back end and bringing 91's developer base onto an integrated Baidu cloud platform.
At the same time, we are pushing forward a new paradigm we call Light Apps, an initiative we unveiled at Baidu World a few months ago.
While app stores are an excellent distribution channel for native apps, particularly for popular and frequently used ones, less frequently used apps can get lost.
Currently in China around 0.1% of apps account for 70% of our downloads.
In other words, the other 99.9% compete for the remaining 30% of downloads.
Light Apps have all the power and functionality of native apps and are easily discovered through Baidu's search, but unlike native apps, do not need to be downloaded.
For this reason they are an ideal format for that 99.9% of less well known, less frequently used apps.
To give you an example, a user may look through classified listings a few times a year for a used car or rental apartment.
So there's no real need to have a classified native app sitting on their device, formatting those classified listings, as the Light App gives the user the same functionality as with the native apps without taking up space on the device.
Again, the app is easily searchable, even if the user doesn't know its name.
This is tremendous potential to improve and streamline user discovery of mobile internet contents and services.
While we are still in the early stages of development with Light Apps, with a limited number of developers invited into this space, I am convinced they have big role to play in the future.
With a daily active user base of 130 million and counting, our Mobile Search platform can be a powerful alternative distribution channel for app developers that are not benefiting from the current level.
Native apps will continue to be important and co-exist nicely with Light Apps.
So for the next several quarters our strategy is to gradually expand the Light App model to complement our native app distribution capabilities.
In terms of our core search offering, this quarter we made further improvements in natural language processing, deep learning, image recognition, voice technology and use of big data.
These key technologies let us predict better than ever what users are searching for.
For example, I can input a search term, what movies is Jennifer Anniston's former husband's partner in.
Baidu then deciphers the relationships in the search term and returns a comprehensive, structured data search page with Angelina Jolie's movies and image tiles.
The user does not need to know the exact name of the actress and he can play one of the movies in three clicks or less.
To the user, this result is simple and direct.
The search is powered in the backend by our vertical landing page and sophisticated technology such as deep learning and natural language processing.
We also continue to deepen data integration across the board with our own vertical services as well as with partners to deliver a more interactive search experience to our users.
For example, in our medical vertical, we are now partnered with over 700 hospitals to enable online advisory, medical appointment booking, online reviews and other actions right on the Baidu search page.
Our customers have seen very meaningful returns with this vertical approach.
In the online game vertical, for example, customers who opt in to our iwan.baidu.com online gaming portal have on average same user registration conversions tripled and online increased nearly 50% compared to standard search marketing.
We are already working on going deeper in additional verticals such as online travel, financial services and education.
Both for our customers and for us, the commercial potential here is significant.
As Baidu grows, so too does our responsibility to protect our users.
That is why we are forging ahead with our netizens rights protection initiative.
This quarter we removed the upper limit on the amount we compensate users who may have been defrauded or harmed by our sponsored link on the Baidu platform.
Today I believe that Baidu is doing more than any other company to foster a safer, fairer, online involvement.
This will inevitably benefit not just our users, but also our platform as a whole in the long run.
On the product side, uptake of our core services grew strongly in the third quarter.
Our internal tracking shows that we are the clear number one in mobile search and we are continuing to gain market share.
The total install base of our flagship Mobile Search app at the end of the third quarter was over 330,000 million, representing an increase of 50% quarter-on-quarter.
Our search app is an important source of organic traffic for Baidu and its embedded features such as Web Search, Image Search, QR Code Scanning and OCR Word Translation provide the best overall user experience.
This growth continues to accelerate and it has been the fastest growing source of Baidu Mobile Search traffic over the last several quarters.
Personal Cloud Storage usage has now reached over 100 million accumulated users, growing over 40% from the end of last quarter.
We're now offering users 2 terabytes of free storage and response has been great.
Baidu PCS is increasingly becoming the service users' turn-to for all their content storage needs across all forms of media, from their Baidu music playlist and Baidu video, television shows, to their Baidu library documents and photos from Baidu Photo Wonder.
Our LBS offering now has over 140 million monthly active users, up from nearly 120 million monthly active users at the end of last quarter.
This growth is a reflection of the continuous improvements we are making from our LBS functionality and content.
Baidu Maps continues to build on its strength as the key mobile gateway for local search and it has grown into a broad platform facilitating a wide range of queries and transactions.
In the past quarter the number of transactions completed on Baidu Maps, including hotel bookings, movie ticket purchases, group buying and taxi bookings continue to increase.
Hotel bookings on Baidu Maps, for example, doubled from the second quarter to the third quarter.
We were the first to offer a free premium navigation product in the third quarter and we are now offering street view in a growing number of cities.
Our majority investment in group buying site, Nuomi, announced that during Q3 both our ability to offer a fully integrated user experience, Nuomi's depth of experience and the geological [self] coverage in the dynamic growing buying industry, make it a natural fit for our LBS offering.
Moving on now to the customer side, all signs this quarter pointed to our customers really embracing mobile and monetization has ramped up very healthily.
Back in the second quarter we rolled out our integrated PC and mobile bidding system which continues to be well received by customers.
Now three-quarters of our Mobile Search revenue comes from customers' trend through actively bidding on mobile.
The same proportion of our Mobile Search revenue comes from spending from customers with mobile-optimized landing pages.
We provide customers with a comprehensive range of app formats, as well as a range of simple and powerful tools to facilitate the transition to mobile.
App formats such as [pay-for-call] and click-to-chat and easy to use tools like Site App are helping our customers get better mobile results.
Increasingly our customers are saying that Mobile Search marketing is a channel we must employ as the percentage of mobile traffic to their site continues to rise and the trends of rapid mobile adoption continues.
More and more of our customers, both SME and large customers across industries, see Mobile Search as a vital complimentary marketing channel to PC Search.
For example, an SME in Shanghai that operates a chain of vocational training centers has been a PC Search marketing customer since 2005.
They started Mobile Search marketing at the end of last year as a way to differentiate themselves from the competition.
Using Baidu's Site App tool to optimize their mobile landing page, they have seen great results from their Mobile Search spend which now accounts for 30% of their total marketing spend on Baidu platform.
That is up from 8% last year.
To share another example in a different segment, one of our large customers in the online travel space saw mobile as a portion of its business grow tenfold in the span of a year.
Baidu worked closely with the customer to optimize their mobile landing page and better target their users, resulting in a very meaningful increase in its mobile conversion rate.
The customer has quadrupled their Mobile Search spend and nearly doubled their overall search spend on Baidu over the last couple of quarters.
In the third quarter we broadened our Plus V initiative, a program in which we (inaudible) our customer base for proof that they are legitimate, licensed businesses.
A large majority of our customers now have Plus V verification, which provides them with a blue Plus V logo in the sponsored links and provides incentivized options to advertise on Baidu.
The benefit of this is that we have a higher quality customer base which is good for both users and customers and good for Baidu in the long run.
In the short term, this Plus V initiative may have a slight negative impact on our absolute customer number account, but demand for search marketing on Baidu continue to search and customers continue to look to Baidu to bring a large scale (inaudible) and measurable ROI.
Our focus on serving quality customers and improving our monetization capabilities has helped drive up ARPU.
In addition, we have started to make efforts to expand our business beyond just online marketing services.
Online gaming is becoming a more important business for Baidu as we build a portfolio of game resources to leverage our distribution capabilities.
PC Search is a powerful channel for web games and the acquisition of 91 Wireless not only complements our pre-existing game distribution capability in Mobile Search and mobile assistant, but also provides us with 91 Wireless's capabilities as a mobile game operator.
Gaming is a highly monetizable industry and it will become a more meaningful part of our business in the future.
We see huge opportunities ahead and we will look to grow this area going forward.
A couple of updates here on our invested entities.
The integration between PPS and iQiyi have gone smoothly.
The combined platform is number one by total monthly time spent on PC [and mobile] (Company corrected after the conference call), according to our research.
Baidu now remains a strong support of iQiyi to grow its position in this important strategic vertical.
Finally, as you know, our invested entity, Qunar, has filed for an IPO.
Baidu has been a majority shareholder in Qunar since 2011.
As Qunar is currently in inquiry period, we will not be able to elaborate more on this topic until the IPO process is finalized.
You can refer to the publically available IPO prospectus for additional details.
So in summary, we were delighted to maintain strong momentum into Q3 after a breakthrough second quarter.
Our leading positioning search app distribution, LBS and cloud computing continues to promote a rich and diverse ecosystem and we substantially bolstered our application distribution capabilities with the acquisition of 91 Wireless and the introduction of Light Apps.
All this is translating into strong traffic and revenue growth, with mobile playing an increasingly important role.
There is still a long road ahead, but for us it's about continuing to execute on the strategy that has proven to be so successful over the last couple of quarters.
Over to you, Jennifer, for a deeper look at the financials.
Jennifer Li - CFO
Thank you Robin.
Hello everyone.
We were pleased to maintain strong financial growth this quarter as we continued to expand our business and ecosystem.
It's clear that the investment we've been making in mobile are paying off, with mobile continuing its strong momentum both on the usage and monetization front.
Also during the quarter we continued our aggressive investment in sales and marketing, infrastructure and R&D, with particular focus on mobile.
Q3 also marked the first full quarter that PPS was consolidated into our financials.
91 Wireless closed on October 1st and Nuomi is expected to close in the fourth quarter.
Looking ahead, we expect our core search business to continue its solid growth.
We're focused on building our organic fundamentals, further complimented with strategic investments.
Our business is on a solid trajectory and we'll continue our aggressive investments in sales and marketing, infrastructure and R&D, with particular focus on mobile.
We'll also continue to support our video business through investments in bandwidth and content.
Now moving to the financials, all money amounts are in RMB unless stated otherwise.
For the third quarter, total revenue was RMB8.9 billion, representing an increase of 42% year on year.
During the third quarter, Baidu had approximately 464,000 active online marketing customers, a 19% increase from the corresponding period in 2012 and a 1% decrease from the previous quarter.
The slight drop was a result of the broader rollout of our plus V verified account program which improves the quality of our customer base.
Revenue per online marketing customer for the third quarter was approximately RMB19,100 a 19% increase from the same period in 2002 and an increase of 19% from the previous quarter.
Traffic acquisition cost as a component of cost of revenue in Q3 was RMB1 billion or 11.7% of total revenue as compared to 8.66% in the corresponding period in 2012 and 11.6% in the second quarter of 2013.
The increase in TAC cost mainly reflects the increased contribution of contextual ads and hao123 promotion through our network.
Bandwidth and depreciation costs as a percent of revenues in Q3 were 5.8% and 4.2% respectively compared to 4.3% and 4.4% in the corresponding period of 2012.
The year-over-year increase in bandwidth cost was mainly due to the consolidation of iQiyi.
Content costs as a component of cost of revenue were RMB222 million representing 2.5% of total revenues compared to 0.5% in the corresponding period in 2012 and 2% in the previous quarter.
The increase was mainly due to iQiyi.
Selling, general and administrative expenses in Q3 were RMB1.4 billion, an increase of 115% year-on-year mainly due to promotional expenses for mobile products.
R&D expenses in Q3 were RMB1.1 billion, an increase of 77% over the corresponding period in 2012 primarily due to an increase in the number of search -- R&D personnel.
Share-based compensation expenses which were allocated to related operating cost and expense line items increased in aggregate to RMB143 million in the third quarter from RMB57 million in the corresponding period in 2012.
The increase was primarily due to the lengthening of option terms for some grants.
Operating profit for Q3 was RMB3.3 billion, an increase of 1.2% over Q3 2012.
Total headcount as of September 30 2013 was about 26,400 employees of which roughly 5000 were accounted for by Qunar, iQiyi and PPS.
We added 2400 more employees from the previous quarter primarily in R&D.
Income tax expense was RMB588 million for the third quarter.
The effective tax rate for the third quarter was 16.3% compared to 13.5% in the corresponding period in 2012 and 16.3% in the previous quarter.
Net income attributable to Baidu for Q3 was RMB3 billion a 1.3% increase from the corresponding period in 2012.
Basic and diluted earnings attributable to Baidu per ADS for the third quarter of 2013 amounted to RMB8.65 and RMB8.63 respectively.
Net income attributable to Baidu excluding share based compensation expenses a non-GAAP measure for Q3 was RMB3.2 billion a 4.1% increase year-on-year.
Basic and diluted earnings attributable to Baidu per ADS excluding share-based compensation expenses both non-GAAP measures were RMB9.06 and RMB9.04 respectively.
As of September 30 2013 the Company had cash, cash equivalents and short term investments of RMB43.3 billion.
Net operating cash inflows for the third quarter of 2013 was RMB4.3 billion.
Capital expenditures for the third quarter of 2013 were RMB780 million.
Now let me provide you with our top line guidance for the fourth quarter of 2013.
We currently expect total revenues for the fourth quarter to be between RMB9.22 billion and RMB9.48 billion representing a 45.5% to 49.6% year-on-year increase.
Please note this forecast reflects Baidu's current and preliminary review and is subject to change.
I will now open the call to questions.
Operator please go ahead.
Operator
The question and answer session of this conference call will start in a moment.
(Operator instructions).
Your first question comes from Alex Yao from JP Morgan.
Please ask your question.
Alex Yao - Analyst
Good morning everyone.
Thank you very much for taking my question and congratulations on a very strong quarter.
My question is on a new initiative you guys launched recently the internet banking service.
Can you talk about your thoughts on this initiative, how you guys want to position yourself in this year and how do you think about the monetization potential?
Thank you.
Robin Li - Chairman and CEO
Alex I expect that the internet banking service we just launched a couple of days ago is in line with our overall strategy based around the landing page.
There are quite a number of very important verticals for Baidu many of the large customers come from but we just don't believe that a simple title and summary which leads the user to a website from those traditional industries would serve users the best.
In fact we can come up with better user experience by integrating more services into this kind of vertical website.
So we have been doing this for travel, for video, for education, health care -- finance is not an exception.
We also see a lot of opportunities when the whole world -- I mean whole China, the offline is moving online but they are not very sophisticated in embracing the internet and they need help.
So we came up with ways to do our work which is traditionally more than a typical search engine would do but we think that would provide a better user experience.
So the internet banking services which launched is in line with this and we believe finance is a very important vertical for Baidu going forward.
Operator
Your next question comes from Jiong Shao from Macquarie.
Please ask your question.
Jiong Shao - Analyst
Good morning.
Thank you for taking my question.
I have a question on Light App.
I know you launched that initiative or announced it at Baidu World.
I was hoping you could share with us some of the metrics at this point, for example how many apps right now in your Light App platform or on your Light App platform and what do the daily downloads look like?
What type of apps fit best with this platform and how easy it is for developers to change or modify their native apps to Light Apps?
Thank you.
Robin Li - Chairman and CEO
Yes we have received a lot of enquiries from all kinds of different verticals.
Many of them have very strong monetization potential but we would like to start from something that is easier for the developers to manage.
We at this current stage only selectively opened this up to a number of developers in verticals like news or classified.
The developers or customers who worked with us have seen very encouraging results.
But this is a very early stage product so we are continuing to improve our technology and to make this available to -- we will make this available to more verticals that can benefit more from the Light Apps ecosystem.
Operator
Your next question comes from Dick Wei from Credit Suisse.
Please ask your question.
Dick Wei - Analyst
Hi thank you for taking my questions and congratulations on this strong quarter and guidance.
I have two quick questions on mobile.
First of all whether Robin can come in on the monetization gap between mobile search and PC search now?
How does that gap trend for the past couple of quarters and then what about going forward?
Also related to mobile also whether you can comment on the TAC dynamics?
It looks like we are relatively flat as TAC as potential revenue.
Was it mainly because of the lower TAC from mobile because of large organic traffic or was it because we [are less reliant] on the PC traffic from the third party?
Thank you.
Robin Li - Chairman and CEO
Okay I will talk about the mobile monetization and let Jennifer talk more about the TAC thing.
Mobile monetization has been growing very very quickly over the past couple of quarters so the CPM [or IPM] growth is faster than the traffic growth -- even faster than the traffic growth.
Yet it is not reaching the level of PC monetization yet.
We certainly see the gap is quickly closing but exactly when it will catch up is another question and right now we think that the highest priority is still to provide the best user experience so that they will very much depend up on the Baidu search app to get information and services.
Once we are more confident about that we will give you more quantitative numbers on the monetization thing.
Jennifer Li - CFO
With regards to TAC -- TAC over the past couple of years has been on the trajectory to increase as a percent of revenue.
We have stated that the main factor driving that is the effort to grow our contextual ads business as well as promoting our hao123 product.
Each quarter because of the mixed components of all the contributing factors you might see some slight variation but I would not say that this Q3 TAC percent of revenue is a reflection of the future trend.
We continue to use the -- distribute our partner's site, the network to promote our contextual apps business as well as use that to promote our own products and I do expect our continued -- the TAC percent of revenue will continue to increase.
Operator
Your next question comes from Alicia Yap from Barclays.
Please ask your question.
Alicia Yap - Analyst
Hi good morning.
Thanks for taking my questions.
So I actually have follow up questions on the TAC going forward.
So I think Jennifer you just mentioned that it will continue to increase.
I just wanted to understand with some of the new business with consolidations on 91 and Nuomi how should we look at for the gross margins trend?
Would that be a more positive impact or negative impact and as well as on the sales and marketing trend will the consolidations actually lead to higher expenses and some margins pressure or margin expansion?
Thank you.
Jennifer Li - CFO
Yes as stated we are in the mode and continuing in this phase to aggressively promote our products.
With regards to gross margin the consolidation of new businesses in the fourth quarter will not materially impact the gross margin per se.
I would say if you are looking at the forecast for our business the fundamentals continues to be driving primarily by our core business and not these invested entities.
They in general do not make the kind of margin that the search business model does.
So in general they do not help per se but because their relative size is so small they don't make material impact -- these two ventures you just talked about.
Specifically with regards to operating expenses we have our foot on the pedal to really push our sales and marketing aggressively promoting our mobile products.
As you have seen over the last quarter the install app for our search -- the core search app is growing by 50% quarter-by-quarter.
You can see that we are really aggressively pushing our products through these channels and will continue to use these different channels and ways to build our product presence.
So you should expect that I am not seeing that we are lessening our efforts in promoting our products and you should continue to see the step up of SG&A expenses as a percent of revenue.
Operator
Your next question comes from Gene Munster from Piper Jaffray.
Please ask your question.
Gene Munster - Analyst
Yes good morning and congratulations.
I apologize if I missed this but can you give any context into how 91 factored into the revenue guidance for the December quarter?
Thanks.
Jennifer Li - CFO
For the Q4 guidance the main driver as you can see we operate on such a large base and our core search business is the organic fundamentals of our business.
That business continues on this solid growth.
Q4 will be the first quarter that we consolidate 91 Wireless.
From some [priorly] made available public information you can get a feel of the scale of its revenue size as relative to the Baidu overall picture.
In comparison it is really low in terms of the overall contribution but because if you are looking at 91 it was 0% in Q3 of course it is an added benefit for Q4 sequentially but overall I would say our business will continue to grow and the strong guidance in Q4 is a result of our core business that is continuing to perform very well.
Operator
Your next question comes from Philip Wan from Morgan Stanley.
Please ask your question.
Philip Wan - Analyst
Hi thank you for taking my question.
As a follow up question on your Light Apps strategy.
I wonder if management has any targets say by the end of this year?
How many applications of developers would you like to have on your Light App platform?
Then also what is your plan to monetize your Light App platform going forward?
Thank you.
Robin Li - Chairman and CEO
Yes right now I think that the main hurdle for mobile search is that many of the content oriented websites do not have a mobile friendly version yet.
So for the whole year this year until the end of the year my mobile search team's priority is really to help convert those PC centric contents into mobile friendly content.
Light App would be a more material thing next year.
We are working with many prospects to come up with a Light App.
But eventually Light App will be an integral part of the overall mobile ecosystem which includes the data or content to even mobile sites the Light Apps, native apps.
They will be combined to serve the needs of our users.
So at this stage simply, quite thoroughly are not going to give you a number on the number of developers or a percentage of results showing Light Apps.
We hope we will be able to do this sometime next year.
Operator
Your next question comes from the Alan Hellawell from Deutsche Bank.
Please ask your question.
Vivian Hao - Analyst
Hi this is Vivian on behalf of Alan.
We have a question regarding the competition on the mobile search front.
How do you view the competition from the new combined entity of Sogou and Soso which is reported already to have around 16% of market share?
Probably we were expecting more synergies with (inaudible) support.
As mentioned on the sales and marketing front we probably will still see the surging sales SG&A for promoting mobile.
Just trying to understand the landscape here of competition on the mobile search front.
Thank you.
Robin Li - Chairman and CEO
Mobile search is still very early.
We talked about our strategy of integrating PC content, mobile content, light app and native app.
We are quickly making a lot of improvements for our mobile search and we think at this time Baidu mobile search provides the best user experience far ahead of any competition.
As a matter of fact based on our internal tracking we continue to gain market share over the competition.
And we probably invested a lot more than any of the competitors in the mobile search front.
Because the nature of the early stage development we will continue to aggressively invest both in the R&D front and in the sales and marketing front to present the Baidu mobile search option especially the mobile search apps, in front of our users.
We think this kind of investment is very worthwhile.
It's actually, you know, a very pressured timing to spend the money on this.
We think this year and next year will be very, very crucial for the eventual success of the overall mobile strategy for Baidu.
Operator
Your next question comes from Chi Tsang from HSBC.
Please ask your question.
Chi Tsang - Analyst
Good morning and congratulations on a very good quarter and guidance.
I was wondering if you can give us an update on your video business.
If you can talk a little bit about what's happening on the competitive front as well as the trends in mobile as well as mobile monetization?
Thank you.
Robin Li - Chairman and CEO
Yes, I think the video [in both] desktop and mobile in terms of time spend and video views are growing very, very quickly.
Right now it's not a very profitable business yet but the traditional advertising industry is shifting the TV commercial budget to video and we think eventually this will become a very material part of the overall online advertising business.
So our focus right now is still to continue to build the best user experience for video both on desktop and mobile and there's no doubt that eventually this will become a profitable business for us.
Operator
Your next question comes from Wendy Huang from Standard Chartered.
Please ask your question.
Wendy Huang - Analyst
Thank you.
I wonder if you can share your thoughts on the major difference of China's mobile search market versus the US and Korean search markets, and also what will Baidu do differently versus your global peer such as Google and Naver use their mobile search technology or mobile advertiser (inaudible).
And also I noticed that Google recently actually started to provide full payment and are getting deeper into e-commerce fronts.
So Baidu actually used to have some major efforts on the actual e-commerce front, so could you give us some update on that as well?
Robin Li - Chairman and CEO
Again, I think for all of the countries or markets you mentioned, China, US, Korean, mobile search is in its early stage.
So we are exploring all kinds of different things to better serve our users' needs.
One trend we have seen is that mobile users in China are increasingly now expecting an end-to-end solution instead of just a fact-finding, so users are not satisfied enough to just find information or find a link to some website on their mobile phones.
They expect to be able to served.
For example, when a user searches for a movie title we should be able to let him or her to buy the movie ticket at a theater nearby without leaving the mobile search app.
So this is the so-called end-to-end solution and we're doing this more and more.
We see this as a trend in China.
Whereas for other markets, which I'm not very familiar with so I'll just take some anecdotal saying to compare.
So in the US people probably are more used to do these kind of things through a vertical app or a mass service but in China I think more of our users prefer to start from the Baidu search box or the Baidu search app.
Also, because China's nature as a developing market, the offline businesses, the traditional businesses are not very savvy in terms of internet, especially mobile, so we need to do more than the internet players in the developed market.
This also presents additional opportunity for Baidu.
If we do more we should be able to make more out of this kind of service.
Operator
Your next question comes from Eddie Leung from Merrill Lynch.
Please ask your question.
Eddie Leung - Analyst
Hey, good morning.
Thank you for taking my questions.
You guys have been making quite some progress on mobile search but I have a question on your PC search.
I understand that it seems like you have been improving your results as well as your monetization system on PC search while some of your competitors are probably focused more on distribution.
However, according to different traffic reports recently it seems like your competitor continues to take some drop its share, so just want to get some of your thoughts on the longer term competitive landscape for PC search.
Thank you.
Robin Li - Chairman and CEO
Eddie, I think longer term the market share is going to be decided largely by the quality of the search or the user experience you provide, and on this front we, you know, undoubtedly have the edge over our competition.
Having said that, we acknowledge that a small percentage of search traffic can be directed through certain control of channels like a browser.
So you see that Microsoft controls the IE browser so they can gain a certain amount of search traffic through that browser.
Certain domestic competitors in China also control a percentage of the browser market so they can control a certain percent of the search traffic on PC.
But at the end of the day Baidu is a very strong brand in search in the mind of Chinese internet users and we provide a superior user experience for those users who do care the quality of search.
We think Baidu is the choice for them.
So going forward we are quite confident that by providing the best user experience, combined with the strong search brand, we are continuing to dominate the PC search market.

Your next question comes from Muzhi Li from Citigroup.
Please ask your question.
Muzhi Li - Analyst
Hi, good morning.
Thanks for taking my questions.
I have a question about the mobile monetizations.
What's the revenue contribution from the mobile side in the third quarter?
And in terms of the mobile search category, what is the top advertising category on the mobile side?
Is there any big difference from the PC's?
Thanks for that.
Yes, thank you.
Robin Li - Chairman and CEO
We decided not to disclose the exact percentage of mobile revenue quarter by quarter.
We just like to qualitatively say how pleased we are about the mobile traffic monetization growth and the potential.
We will probably disclose this number when we think there's some material change that will shape the overall benefit for Baidu.
In terms of top categories, we think it's pretty much similar to the desktop search.
Jennifer, do we have more color on that?
Jennifer Li - CFO
I think there's -- our customers are, as you know, using the integrated bidding system to promote their products and services on our platform, both through the PC as well as mobile.
So there is not much of the advertising sector difference compared to the -- compared to PC.

Your next question comes from Piyush Mubayi from Goldman Sachs.
Please ask your question.
Piyush Mubayi - Analyst
Robin and Jennifer, congratulations on a very strong number and your guidance for the fourth quarter.
Could you talk about the contribution from the key customer categories in the fourth quarter and in the last quarter, and in particular could you shed some light on how e-commerce is panning out?
Thank you.
Jennifer Li - CFO
If we look at our key sectors where the revenue contributions are amounting the top.
In the past we've provided the top five sectors, and in this quarter I would name the top five sectors continue to be consistently the same, namely medical health care, education, travel, machinery and equipment, and online games.
So these factors has been consistent.
With regards to e-commerce we do separately from a different angle to look at e-commerce growth and overall e-commerce grew very strongly, I would say both on the q-on-q and year-on-year basis.
It's growing faster than the larger -- the overall average.

Your next question comes from Andy Yeung from Oppenheimer.
Please ask your question.
Andy Yeung - Analyst
Hi, good morning.
Thank you for taking my questions.
Can you give us some color on the trend for your natural traffic versus acquired traffic in both PC and mobile search, and how would you see those trends impacting your traffic (inaudible) in the long run?
Robin Li - Chairman and CEO
As I've said in the prepared remark, the -- you call it natural traffic, we call it organic traffic -- Baidu has been growing faster than the acquired traffic.
We see this as a trend and it's a very positive trend that we are providing good user experience and our brand is better and better recognized by the mobile users.
And in terms of PC, I think the traffic mix has been relatively stable.
Jennifer Li - CFO
And with regards to the tag composition related to search traffic, as I've highlighted, the tag changes are mainly driven by contextual business that's non-search traffic related, as well as the Hao123 promotion.
So if the tag itself, its movement is not a reflection of, you know, it's consistent with what Robin is saying.

Your next question comes from Ming Zhao from 86Research.
Please ask your question.
Ming Zhao - Analyst
Thank you for taking my questions.
My question is on the vertical approach.
So I assume you are talking about the [inaudible] system.
I'm not saying that it's good for user experience and to keep them on your properties for a longer time, but from a monetization perspective does that mean a significant increase in ad inventories?
So it is addition to the Phoenix Nest or is it going to replace it in the long run?
And also maybe Jennifer, could you comment on margin outlook for the fourth quarter and beyond?
Thank you.
Robin Li - Chairman and CEO
Yes, in terms of the [inaudible] vertical, we are trying to change the format of both the content and the sponsored content.
We just don't believe that a simple title and summary is the best way to present this kind of information to our users.
By having a more sophisticated way of presenting this kind of information, we are able to in general create better ROI for our customers.
So that will increase monetization eventually and it's not really an apple to apple comparison in inventory, it's more about a different form of inventory.
Jennifer Li - CFO
And with regards to margin, as you know we're very focused on growing our top line business and manage prudently our investments which go through the expense line items.
The margin is never a target for us but I do, you know, have -- I have in the past provided some guidance, you know, to try to be helpful.
Over the past two quarters I've said that for the whole year, the last two quarters are reflective of the year-over-year for the whole year's operating margins kind of a change for the yearly basis, and for the past Q3, as you can see a lot of the line items the pattern continues to hold.
I would highlight that going into Q4 the tag will continue to increase as the general trend is consistent with last year.
At the same time we are stepping up our SG&A expenses to promote our mobile products.
So this I have indicated in the past that second half SG&A expenses will step up because a lot of our products are ready.
For the whole year I think the guidance will be consistent, as I've said in the past, and I would say, you know, over the past two quarters, Q1 and Q2.
If you see 12% to 13% as the indicative for the whole year's operating margin change level, I would think it was more the higher end, as now we fold it into PPS and, you know, new business entities that are not generating the kind of operating margin as the main business.

Your next question comes from Eric Wen from China Renaissance.
Please ask your question.
Eric Wen - Analyst
Hi.
Thanks for taking my questions and congratulations on the good quarter and guidance.
I just have one question in terms of 91 Wireless.
How shall we model the intangible amortizations and goodwill allocations heading into fourth quarter and beyond?
Thanks.
Jennifer Li - CFO
There will be some intangible amortization going through operational cost line items.
We have, you know, going through these line items in the past you have seen related to Qunar to iQiyi as well as PPS and there will be further items going through this.
It's hard, you know, I think to specifically pin down this, at this point is not the way that we have done in the past.
I have tried to give you the indication between operational cost and content cost.
If you look at that together the Q4 level I would say the step-up compared to Q3 mirrors the Q2 and Q1 relationship -- or Q3 and Q2 relationship.

Your next question comes from Cynthia Meng from Jefferies.
Please ask your question.
Cynthia Meng - Analyst
Thank you, Jennifer and Robin, and congratulations for the good result.
My question is regarding the CPC on mobile.
We hear anecdotal comments about mobile CPC being 50% of that of PC.
Just want to know if management has seen any trend, that the gap between mobile CPC and PC CPC being narrowed.
Thank you.
Robin Li - Chairman and CEO
I kind of answered this question previously.
The gap is certainly narrowing but the CPC for mobile is still lower, meaningfully lower than on PC.
