Google has signed up to be the exclusive provider of all advertising on eBay sites outside the US, and will also integrate click-to-call services (which allow customers to click on a link to be connected to the advertiser via an internet telephone call) via a partnership with the eBay-owned Skype and Google Talk.
Whenever a bidder looks for a product on eBay, Google will provide related text-based search links.
The service will launch in early 2007 and will be tested over a period of several months. Financial terms include a revenue share, although the companies have not revealed specific details.
This deal is the latest in a series of attempts by Google to diversify its income away from its core search site. Last month, it agreed a deal with News Corporation to sell search services across Fox Interactive sites.
"This agreement underscores how much we value eBay as a partner," Eric Schmidt, the chief executive of Google, said. "By working together to promote click-to-call functionality through Google Talk and Skype, we are offering advertisers another innovative way to connect with customers."
