Shedding light on Google’s latest thinking about “the perfect ad,” Google’s vice president of product management, Susan Wojcicki, ran through five demos in 10 minutes at the Web 2.0 Summit today in San Francisco.

Wojcicki, who is in charge of the design and innovation around Google’s ad and measurement platforms, talked about ways to enhance advertising effectiveness through a combination of web search, location-based mobile phone technology, and photo imagery. The demos worked, for the most part, and provide a glimpse into how Google can make search advertising more useful, immediate, and lucrative.
