Yahoo takes a page from Google
In addition, Yahoo has started testing "Web Rank," an algorithm that measures the popularity of a Web page, from 1 to 10, based on how many other sites link to it. People can view the Web Rank measurement bar by downloading a new version of the Yahoo Companion toolbar, which lets them search Yahoo anywhere from the browser. Yahoo's Web Rank closely mimics Google's PageRank, the No. 1 search company's star algorithm for calculating search results. PageRank appears as a little green bar line in Google's own toolbar.
