You’d have to search a long time to find someone who’s been closer to the evolution of Google than Susan Wojcicki. It was in her rented garage that Sergey Brin and Larry Page launched the company, which she joined in 1999.

Today, while much of the attention on Google focuses on Android or Chrome, Gmail or YouTube, Wojcicki oversees the operations from which Google generates the bulk of its revenue and profits: AdWords, AdSense and DoubleClick among them. And in October she was made one of Google’s eight senior vice presidents.

She’s lately been quoting research from Forrester, which found that while 42 percent of people do research online before buying something, only 7 percent of those purchases happen online. Mobile advertising, she has argued recently, can help bridge that gap. Expect lots of discussion around that stemming from last year’s $750 million acquisition of mobile advertising firm AdMob.

Meanwhile, let’s be honest: Everyone wants to know what really happened between Google and Groupon.

Liveblog

8:36 am: Everyone is seated in the ballroom, and the session with Wojcicki is about to start.

8:39 am: Walt and Kara have come out onto the stage, thanking the audience for their support at big D and this week at D: Dive Into Mobile.

Before Wojcicki comes to the stage, they are introducing the new writers at All Things Digital:

• Liz Gannes, NetworkEffect
• Ina Fried, Mobilized
• Tricia Duryee, eMoney
• Arik Hesseldahl, NewEnterprise
• Drake Martinet

8:43 am: Walt and Kara hand the stage off to Peter Kafka, who will be conducting the interview with Susan Wojcicki.

8:44 am: We’re getting started. Peter Kafka is interviewing Susan. She says when she first rented to Larry and Sergey, they weren’t allowed to come in the front door.

8:45 am: Susan: I charged them $1,700 a month in rent.

8:45 am: Peter: Let’s start with mobile. It’s a big business but small for Google at $1 billion. Break out that billion dollars.

Susan: We don’t break it out. But they are all growing. To give you an idea of the growth, we saw a 4x increase year over year in the number of searches. AdMob has doubled, and is doing more than a billion ad requests per day.

8:48 am: Mobile brings an opportunity not just to bring people to a Web site but to a store. We just did something with Google Ad Goggles, with Buick, where you can see a magazine ad, scan and that takes you to an ad site.

8:51 am: Peter: In-app advertising is a small opportunity, but Google owns it.

Susan: We’d like to have everyone be an advertiser. We think about having very mobile-specific campaigns.

Our barriers to entry are a lot lower than those at Apple. We offer all the formats like video. We want it to be easy to advertise, we have a lot of systems that measure quality.

8:52 am: Peter: Who’s running AdMob day to day? Original management has left.

Susan: We’ve taken different parts of it and integrated it into our advertising and sales organizations. [Former AdMob CEO] Omar [Hamoui] has left for personal reasons, but pretty much most of the staff who joined with AdMob have stayed. The goal is how do we continue to innovate on that platform.

Peter: Do you view the phone differently from a privacy standpoint than on the PC?

Susan: I think the phone is a really personal device in a lot of ways. If you drop your phone or lose it there’s a moment of panic. On the other hand there’s a lot of control that users have.

8:57 am: Peter: You guys and the rest of the ad industry are telling Washington that they will self-regulate around privacy. FTC says that’s not going to fly, and they want something like an opt-out browser.

Susan: Google is a consumer brand and people need to be comfortable. If we were just an advertising brand we wouldn’t have the same concerns. We’ve always tried to promote transparency and choice among our users. We didn’t have a cookie on the AdSense network until about a year ago. There were a lot of things we couldn’t do.

8:58 am: Susan: We’re always interested in what’s being proposed. We’ll always participate in any discussion around proposals to improve privacy for users.

8:59 am: Peter: Do you think users really care about this? They’ll say they care if you ask them. Practically, do they really care?

Susan: People care. They also want to have good content. And they want the advertising to be relevant. We see advertising as information, and as long as we can make that information useful, the better it is.

9:01 am: Susan: We’ve had ads in Gmail since Gmail first launched. Ads get a bad reputation sometimes because theyr’e not useful. They’re not relevant, or slow. If you’re planning a trip to Hawaii, and see ads that are related to that, that’s useful information.

9:02 am: Susan: The moment that our products are not as good, people will go somewhere else.

Peter: So you were employee No. 18; now there are 23,000 employees at Google. Talk about how the culture has changed over time.

Susan: Google is a much bigger company obviously. We’ve tried to have a lot of different divisions and groups and have given them autonomy. Our display group is run like a separate group within Google.

The secret is to break into groups that are manageable, and give them as much autonomy as possible.

9:05 am: Peter: What are we to read into the fact that you’re offering employees bonuses to stay at the company?

Susan: Our employees are really valuable to us. They are basically our business. Google has been doing well. As much as possible we’re trying to share back with the employees. They will continue to create a lot of value.

9:06 am: Peter: If you’re coming to Google as a hot young engineer out of Stanford, what’s the most compelling thing you can say to bring them on board?

Susan: Google’s scale and platform. If you have a passion, and want to get things done. [Cites Andy Rubin, and the scale he's working at now vs. when Android was a start-up.] When you do something, it matters.

9:07 am: Peter: You guys were talking to Groupon. That deal has now gone away. [Asks about integrating companies into the Google culture.]

Susan: Each deal is different and you have to consider how best to integrate them.

9:09 am: Peter: What’s the product you’re most excited about?

Susan: Mobile ads. How can we enable you, when you’re walking around, to find out the best local offers around? As an advertiser, how can I find out if someone saw my ad and went to a store?

The local market is a huge market, we’ve always wanted to be in it.

9:09 am: Now going into Q&A from the audience.

9:13 am: Q: What do you view as being so hard about local?

Susan: The reason local is hard is because it needs to be simple. For small businesses, they don’t have a lot of time. You need to create a model that works for them. And it needs to be easy for them to sign up. On the back end, everything needs to just work for them.

9:15 am: And we’re done!

Here’s how Yahoo’s top brass and board–with the help of its newly re-engaged crisis-management PR firm, Abernathy MacGregor–are already trying to spin the latest executive turmoil to hit the company:

Trashing those on the way out, to take focus off those remaining who have been just as responsible for driving the Internet icon and claiming that this is all part of yet another well-planned reorganization at Yahoo (YHOO).

Don’t believe most of it for a second. Some of it is corporate politics as usual, some of it rejiggering of events, some just not true at all.

After BoomTown’s scoop earlier today that Yahoo’s U.S. head Hilary Schneider, as well as Audience head David Ko and VP of Media Jimmy Pitaro, would be departing the company–all of which Yahoo is still planning to announce after the markets close on Friday–here comes this gem in a follow-up story in The Wall Street Journal:

“[Yahoo CEO Carol] Bartz, who joined Yahoo in January 2009, is in the midst of a turnaround effort. People familiar with the matter said she is removing the company’s old guard to assemble a new team.”

Let’s parse this ridonkulous spin-addled blame game, shall we?

Bartz is, in fact, the very person who picked all those execs for prime responsibility in her last reorg.

If they were so incompetent, why not dump them much quicker? After all, it’s not like the problems have not been mounting for months and months, with more and more talent taking off.

In addition, the exec exodus at Yahoo over the last year has been unrelenting and broad, encompassing way too many employees for her to act as if it were all planned and okay.

As to the “midst of a turnaround effort” canard that Bartz keeps insisting on, even comparing herself to Apple (AAPL) CEO Steve Job’s epic journey to return that legendary company to health?

Um, we are deep in the second year of the Bartz regime, and there appears to be no iPod-like save in sight, and it’s a little long in the tooth to keep using the turnaround excuse for all that has not yet happened under her command.

Which is to say, stock with a pulse and real growth across all metrics, as Facebook and Google (GOOG), to name a few, are showing.

In addition, it was Bartz herself who handed over a lot of the responsibility for the revival of Yahoo to Schneider.

Which meant Schneider had to be thrown under the wheels of the bus in the Journal by dragging out a very old–and tangential to the much larger flat revenue crisis at Yahoo–newspaper deal as pretty wet cannon fodder:

“Ms. Schneider is leaving because officials haven’t been satisfied with her performance, according to people familiar with the matter. Ms. Schneider was responsible for a 2006 deal with industry group Newspaper Consortium, in which Yahoo sold ads for newspaper websites and print editions. The effort continues but has not met Yahoo’s expectations, according to a person close to the company.”

Memo to readers: “People familiar with the matter,” I am guessing, would be current Yahoo execs.

The fact of the matter is that there have been both critics and admirers of Schneider at Yahoo, which comes as no surprise for one of its top execs. Some consider her smart and canny, while others complain of indecisiveness and slowness to act.

And, she has definitely had some very big whiffs, including the newspaper consortium, but most especially not finding an ad sales chief to replace Joanne Bradford, who left in March, about which I gave her a hard time when a very squishy structure was announced.

And, right now, sources tell me, Yahoo’s upcoming quarterly report could be an even tougher one.

And that falls to Schneider, of course, who has been in charge of its many partnerships, as well as advertising sales across the key Americas region.

Perhaps good reason for an ouster, except I have been tracking Schneider’s status for many months now, since hearing from many sources–not her, ever, in case you wanted to know–that she had told Bartz she wanted out.

Maybe that is what began to sour the boss on Schneider. But to now suddenly call her performance poor seems unusual, especially when you can just as easily point to Yahoo’s disastrous and pricey marketing campaigns–it is definitely not You!–helmed by CMO Elisa Steele, which has failed to move the needle on key user metrics.

But she has a tight relationship with Bartz, so she’s all right, jack? I am dizzy from all the spinning.

In other words, execs make mistakes and there is a lot of blame to go around and–as the old saying goes–the buck really does stop with Bartz.

But, guess what? Perhaps it should be noted that Bartz has also misstepped badly of late by making a series of wild remarks that have seriously angered many partners and other companies in Silicon Valley.

And I have heard from countless and very significant investors, all of whom are deeply concerned about her tone and recent public comments.

Just ask Yahoo Japan’s Masayoshi Son. Or Alibaba’s Jack Ma in China. Or the fine folks over at Apple in Cupertino, Calif.

And, I can also report that several execs at Yahoo’s new search technology partner, Microsoft, are also increasingly alarmed. Said one to me yesterday: “It is becoming a little unsettling.”

I can say for certain that Ko, who will doubtlessly be the next to get dinged, left on his own motor, telling Bartz himself recently.

He was quickly followed by Pitaro, who, as I reported earlier this week, is headed to another big company. No matter what the spin, his departure is a big loss, as he is well-liked inside and outside the company.

Then Schneider rounded out the latest trio of execs to go.

Thus, sources said, Yahoo is about to go on the offense, which is the expected thing to do, ready to announce a plan to move most of the product organization under Chief Product Officer Blake Irving.

The former Microsoft (MSFT) online exec is as sharp as a tack, in my experience, and clearly an even sharper corporate player, recently bringing in a series of his old cohorts from the software giant to take over big jobs at Yahoo.

He’s obviously now won some version of a corporate power play, and is now in favor with Bartz. But that means he’s being handed the entire thing.

Apparently, Irving has told numerous people that he plans to “rip it all down” and streamline the whole organization.

More rearranging at the company that has moved around the corporate living room umpteenth times over the past several years? Except it is still essentially the same room and same house.

Okay, Irving should probably have his choice of where the sofa goes, but as one exec wisely told me tonight: “Yahoo needs to build great products, not have another reorg….It needs a win.”

Indeed, just as board member Eric Hippeau apparently said at a recent meeting to deal with the latest executive kerfuffle.

Yahoo Chairman Roy Bostock–who has presided over so many stumbles over the years that I have lost count–said to the room: “We need crisis management.”

Countered Hippeau, a longtime Internet exec who is now CEO of the Huffington Post: “What we need is revenue.”

Indeed. And innovation. And a vision. And, most of all, spin-free leadership.

Google (GOOG) stock has lurched five percent lower in the first few minutes of after-hours trading, as investors digest the news. If you want to anthropomorphize the market, you might speculate that it’s bummed that CEO Eric Schmidt and company didn’t show a higher revenue lift. But if you’re keeping track, revenue is up 17 percent compared with last year, and up 12 percent from the previous quarter.

Here is Citigroup (C) analyst Mark Mahaney’s “cheatsheet” for those playing at home (click to enlarge):

And you can see the company’s profit and loss and balance sheet here.

Google will be using YouTube to livestream its earnings call, but I’ll be providing some annotation here starting at 4:30 pm Eastern. You can also check out the company’s accompanying slide presentation here, and here’s a chart it’s particularly proud of (click to enlarge):

I’m trying out a promising new liveblog tool, but please bear with me if there are bumps along the way.

On the call: CEO Eric Schmidt, CFO Patrick Pichette, product guy Jonathan Rosenberg, sales boss Nikesh Arora. No Larry or Sergey.

Schmidt declares that he’s very pleased with Q4: “An extraordinary end to a roller coaster year.”

Schmidt: Clearly, we were right to start ramping up investments and will continue to do so. We’re investing in people and investing in tech based on our “70/20/10″ rule: 70 percent in core products, 20 percent in new business like mobile/Android, and 10 percent in “long view” initiatives like commerce and social.

And of course, more mergers and acquisitions. We’re continuing on a pace of roughly one M&A per month, some small, some big.

Pichette runs through the numbers in the release above. He reiterates Schmidt’s line about continuing investments.

Jonathan Rosenberg has a cold, but gets his message across: “We made some very hard decisions” to shut down some products to focus on winners. It’s our “more wood behind fewer arrows approach.” We’re focusing on DoubleClick integration, Android expansion and the Chrome OS. “YouTube, is in fact, monetizing well,” and we hope our partners make money, too.

Obviously, going forward, we’re going to plow resources into search. But other stuff too. Social, for instance. Not just social networking, but all of our products should be “social.” This can apply to search, local search, etc. We’re also focusing on commerce, whether people are making their purchases online or offline.

More Rosenberg: Mobile is important, and so is moving enterprise to the cloud.

Arora: We improved throughout the year, and Q4 was strong. Large companies like Staples (SPLS) and Volvo are directing an increasing portion of spending online [as they're supposed to do].

Arora: Search ads are always a value in December! Costs go up but they get more effective because people buy more.

Arora: Brand marketers are increasing their spending too. YouTube has had many successful brand campaigns. Have you seen Fox’s “Avatar” ads? They’re great. Other shoutouts for Sony (SNE) and American Express (AXP).

Arora: Most of the top networks have signed onto AdX ad exchange since we launched it in the fall.

Time for Q&A.

Google’s U.S. revenue had a big jump, but international revenue did not accelerate as quickly. What gives?

Arora: In the U.S., we saw large advertisers shifting offline to online. Other markets have different issues; hence, the different growth rates.

Are we back to normal in regard to seasonal patterns? Also, can you talk about “materiality” of mobile?

Pichette: We won’t talk about mobile revenue in any concrete way.

Arora: There is some different performance by vertical. Finance, obviously, isn’t as strong as it used to be.

Another question about mobile: Is Google trying to push revenue? Profitability? Also, please talk about China.

Rosenberg: Advertisers are starting to figure out what works on mobile. For instance, adding a phone number or an offer for mobile helps a lot.

Pichette: Regarding mobile, we want to drive innovation that in turn drives people to the Web, which is better for us. That’s the core engine of mobile.

Schmidt: “China stuff has been well-covered in the press,” the CEO notes before recounting the China story. “We’re in conversations with the Chinese government,” and our business has remained unchanged. “But in a reasonably short time, we’ll be making some changes there.” That said, we’d still like to be in China.

Missed a question. Apologies.

Please talk about outperformance of network business vs. owned and operated. Also, what accounts for higher marketing costs?

Pichette: Nothing to talk about re: network versus O&O. Re expenses, we said we were going to ramp up investment and we put in more there because we can track the results and the return on investment.

Arora: Yep, some of that money was to support consumer launches.

You said search increased five times on mobile. So what does that mean for revenue per search? Also, please talk more about increased spending on marketing.

Pichette: We’re really pleased with the marketing experiments we’re running.

Rosenberg: Regarding mobile, the new formats, targeting tools and reporting we’re giving mobile advertisers is making a huge difference. But I won’t answer your question about revenue.

Missed another question here.

YouTube monetization: Can you give us some metrics on how much inventory you’re selling?

Arora: Nope. But it has “gone from being a nice-to-have” to essential.

Pichette: The Youtube homepage nearly sold out in Q4. Hope that’s useful.

Can you break out ad spending by advertiser size?

Arora: Large advertisers are moving online, which is good. Retail was strong in Q4. We’re working with smaller advertisers to “bring them into the fray.” But the discrepancy so far has been mainly seasonal.

Can you rank your core businesses in terms of growth potential? Also, what’s up with you and Apple (AAPL)?

Schmidt: We’ve been saying for a while that display is a big opportunity. One story you haven’t seen so far is how successful we’ve been in display, but that will come out in 2010. [Note to PR staff: Start pitching!]

And obviously, mobile is small now but will grow quickly.

“With respect to Apple, it’s probably better to say”…that as a former board member “I have a special spot for Apple in my heart.” They’re a very well run company and “they have some very good stuff coming” strong competitor, etc.

Schmidt on Nexus One: What it is really about is a new way of buying a phone. Nexus One itself is the first in a series of examples where you can buy the phone online and pick your carrier.

Is Bing having an impact on cost per click?

Rosenberg: We think out CPCs are generally not affected by competitors. Prices are set by buyers.

Can you talk about Nexus One’s impact on margin?

Pichette. Not really. We want to innovate, etc. Nexus One will have its own margin and that’s how we’re focused on building the business.

We’ve seen third-party data on mobile projecting that iPhone could account for 50 percent of mobile traffic. Does that make sense to you? Also, you have said that the Apple relationship is “stable.” So what are the odds that you’re going to continue to provide search on the iPhone?

Schmidt: We won’t talk about the market share of Apple. And we won’t “speculate about any deals of any kind–true, not true, rumored, not rumored.”

Given that new display products are so great, is there any notion that people are moving dollars from search to display?

Schmidt: Advertisers “don’t shift, they add.” They might maximize search to maximize revenue and they might spend on display for long-term growth, branding, etc.

Pichette thanks Googlers listening for all their hard work. There’s an auxilary call at 6 pm Eastern with Pichette and Rosenberg, but I won’t be able to cover that one.

Reporting third-quarter results after market close Thursday, Google (GOOG) topped estimates, posting net income that rose to $1.64 billion, or $5.13 a share, from $1.29 billion, or $4.06 a share in the same period last year. Net revenue for the period ended in September rose nearly one percent to $4.38 billion. Excluding items, earnings for the quarter were $5.89 a share. Consensus estimates had been calling for $5.42 a share and $4.24 billion in net revenue. The chart below shows revenue sources within Google (click to enlarge).

Impressive. Seems paid clicks grew 14 percent compared to the same period last year, and four percent compared to the prior period. Cost per click was down six percent year over year, but up five percent sequentially.

“Google had a strong quarter–we saw seven percent year-over-year revenue growth despite the tough economic conditions,” said CEO Eric Schmidt. “While there is a lot of uncertainty about the pace of economic recovery, we believe the worst of the recession is behind us and now feel confident about investing heavily in our future.”

Good to hear. Google’s shares, which have already risen more than 50 percent in the past six months, are on another upward tear. They rose 1.82 percent to $539.27 on the news in after-hours trading.

Earnings call highlights via The Wall Street Journal’s Andrew LaVallee:

4:32: Call starts. The cast is the same as last quarter: Mr. Schmidt, CEO; Patrick Pichette, CFO; Jonathan Rosenberg, SVP of product management; and for the first time, Nikesh Arora, president of global sales operations and business development. But there’s a twist–they’ll be using Google’s moderator to vet questions with voters. They vote on “the most relevant questions,” which go to the Google execs, the operator says.

4:35: “While there’s obviously a lot of uncertainty about the pace of the economic recovery, we believe the worst of the recession is behind us,” Schmidt says.

He adds that Google now has the confidence to invest “heavily” in its future. “It’s all good news from our perspective, at least in looking at the quarter.”

4:37: Says “we want to really get to the perfect search engine” and that many advertisers would like to spend more with Google if the company’s product allow them to do that.

4:38: Schmidt says “we’re open for business in making strategic acquisitions, both large and small.”

4:39: It’s Pichette’s turn. “At a high level, we’re very pleased with our Q3 results,” he says. The quarter benefited from growth in AdSense for content and display initiatives.

4:41: U.S. revenue up 4% to $2.8 billion. U.K. revenue decline affected by foreign exchange as well as ongoing macroeconomic weakness, Pichette says.

4:42: Operating expenses rose from the prior quarter, mostly due to payroll, equipment and facilities-related expenses.

“We believe the worst of the recession is behind us,” he says.

4:44: Brazil was a standout in Latin America, Arora says. We’re beginning to see signs of recovery in Europe and Africa, particularly Spain. In Asia, China performed strongly as an emerging market.

4:46: Looking at the display-advertising business, those have also shown strong results, he says.

On YouTube, new advertisers and partners are helping with monetization efforts. Ninety percent of the top 50 advertisers have run YouTube campaigns with successful results–recent examples include McDonald’s and Hewlett-Packard.

4:47: YouTube has signed deals with all four major record labels and several independent labels. Earlier today, Google announced a partnership with Channel 4 in the U.K., which will bring full-length programming to the video-sharing site.

4:48: Arora adds a personal shout-out to the sales team.

4:50: Rosenberg calls the new AdWords front-end one of the company’s biggest investments of the year. Advertisers have new reports, can run more efficient campaigns and can get new features faster thanks to the platform, he says.
