In a deal between two of the Internet's most prominent properties, Google Inc. will begin selling advertising on Web auction leader eBay and help buyers quickly ring an online merchant to do business.

The arrangement announced Monday promises to introduce "click-to-call" Web site technology to a broader audience and potentially speed its adoption as a means to more quickly connect online consumers with advertisers. It allows potential buyers to call up sellers by clicking a link in a Web page.

"We have a chance to create a whole new way for buyers and sellers to connect online and to create what we hope will be a significant revenue stream for both eBay and Google," eBay Chief Executive Meg Whitman said in an interview Sunday night.

Last year, eBay Inc. bought the Internet phone service Skype. Google has its own messaging and voice telephone service, Google Talk. Both services will be used in the partnership, though details were not disclosed.

Google CEO Eric Schmidt said the agreement with eBay is "likely to go on for many years," but he would not disclose the terms of the deal or what it might mean for the Mountain View-based search engine's bottom line. Whitman said eBay does not expect the partnership to affect its financial performance either this year or next.

Under the partnership, Google would become the exclusive provider of text advertising on eBay outside the United States. In May, eBay announced a deal with the No. 2 Internet search engine, Yahoo Inc., to serve all its domestic advertising.

The second component of the alliance calls for the two Silicon Valley companies to work together on developing a service that lets Web surfers place telephone calls through their computers or handheld devices when they click on a link in an Internet ad.

Schmidt and Whitman said they would begin testing some of their joint services early next year.

Whitman said eBay decided to give Google's advertisers access to its international auction sites after choosing Yahoo for its domestic advertising because of the competing Internet search engines' respective strengths and how they mesh with eBay's assets.

San Jose-based Ebay also owns PayPal, the online payment service, and when the company joined advertising forces with Yahoo, PayPal became the preferred payment provider for purchases made on Yahoo.

Similarly, eBay plans to rely on Google's international presence to build a worldwide market for Skype, the Luxemborg-based Internet phone provider the company acquired last year.

The companies said they would use Skype and Google Talk, the search engine's instant messaging and voice-over-Internet telephone service, to build a search function that lets Web surfers launch Internet phone calls to eBay merchants or Google advertisers by clicking on ads.

Promoting "click-to-call" advertising was also part of the deal eBay announced with Yahoo in May.

Although eBay already was one of Google's biggest advertisers, the search engine launched a rival online payment service to Paypal in June. Schmidt said the overlapping services and partnerships are all part of Silicon Valley's effort to respond to tech-saavy shoppers who want service in a hurry.

"This is all about speed," he said. "The moment somebody wants to buy something, we want that advertiser to be able to sell it, hawk it or do whatever they want with it."
