Michael Slinger, Director of Mobile Ads at Google, shares his expertise and observations about mobile advertising. He explains that after getting a mobile site, most brands ease into the services Google offers —starting with core search and graduating to such things as click-to-call, site links and reviews. While these things are great for connecting consumers to brands and businesses, he also talks about what's on Google's horizon, including plans to improve payment from your phone and improved location-based ads.
