(via Search Engine Journal)> Yahoo! has launched a new web site tracking tool on its Yahoo! Toolbar to compete with Google’s PageRank, named WebRank. Web Rank values range from 1 to 10 in a similar fashion you, with the higher number depicting higher link popularity. Yahoo’s Toolbar collects anonymous URL data about sites visited by toolbar users who have enabled the Web Rank feature and then sends that information back to Yahoo. According to Yahoo, the new toolbar does not collect personal identity information about users. As well as providing another way for Bloggers to assess the popularity of their site, WebRank will help alert Yahoo’s spider robot to the existence of a particular blog, and direct the spider to visit that blog for inclusion in its search index, if it isn’t already in it.
