Google will expand its contextual paid listings program to Web sites published in five foreign languages, the company said Friday.
The search company said its AdSense program, which serves targeted text listings on Web sites, would add Spanish, French, German, Italian and Japanese. Previously, AdSense was available only in English.
Google rolled out its contextual paid listings product in March, hoping to build on the success of its paid search listings. Hundreds of publishers have signed on to display AdSense listings, which pay publishers part of the revenue generated each time a user clicks on an advertiser's listing.
Contextual listings are still a small market, expected by investment bank U.S. Bancorp Piper Jaffray to generate $100 million this year. In 2008, the market is expected to generate $1.4 billion.
Google so far has a wide lead in the space, as rival Overture Services has signed just a few partners. Google further solidified its lead by buying its main competitor, Primedia's Sprinks, in October and subsequently shutting it down. Former Sprinks executives last week landed at second-tier search company Kanoodle, which plans soon to launch a contextual listings product to compete with AdSense.
