Google's Susan Wojcicki: Where we're heading

It's been said before, but it's worth saying again: Susan Wojcicki doesn't get enough credit outside Silicon Valley.

As Google's senior vice president of advertising, her work has been instrumental to the Internet giant's success: Wojcicki spearheaded the advertising platform AdWords, Google's biggest moneymaker, and pushed for the acquisition of YouTube in 2006. And Wojcicki's ad products accounted for 96% of Google's overall revenues last year, bringing in almost $36.5 billion. So it's fair to say that when she speaks, at least within the halls of Google, people listen.

At Morgan Stanley's Technology, Media and Telecom Conference earlier today, Wojcicki weighed in on a number of Google topics. Perhaps top of the heap these days is the issue of Google+, which has been subject to intense scrutiny. A feature called "Search Plus Your World," introduced in January, integrated Google+ photos and posts into Google's search results. The move caused some privacy advocates to cry foul and may have been cause for the U.S. Trade Federal Trade Commission to expand its antitrust probe to include Google+.

"With Google+, it's not just about building a social network," explained Wojcicki. "It's the idea of what is our experience when it revolves around people based on who you know, based on who you have in your Circles, how we [as users] think about the information that we [Google] give to you."
