Google has turned its flagship Internet search engine into a key advertising channel for businesses over the past decade.

But Google has a variety of other online properties that it believes are also well-suited for advertising, and on Tuesday the company began to effort that appears intended to ramp-up advertising on its specialized search engine for images.

GoogImageAdsGoogle executives told reporters at a briefing in San Francisco that its Image Search product, which has cataloged more than 10 billion images of everything from celebrity photos to impressionist paintings, generates more than 1 billion page views everyday – a rare nugget of information about Web traffic from the search giant.

And Google unveiled a new ad format for Image Search that allows marketers to combine images with the text that appear in the ads above regular image search results.

Until now, search ads that appeared in Google Images were for the most part all text (in some cases, the ads had product-specific images). But the new ad formats will allow marketers to include visual images for anything they want: a picture of an alluring beach for a travel agent selling Hawaiian vacation packages, for instance.
