I don't think so... "The name "PageRank" is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999" http://en.wikipedia.org/wiki/PageRank
Yahoo don't have it. Its the way google determines the importance of different webpages. Yahoo have their own criterion for search engine ranking but they don't disclose it possibly.
I heard last year that Yahoo will release their Page Rank... I forgot the name. But I don't know if it was executed.
Just don't care about ranking but look for targeted traffic. Use simple SEO techniques & natural links, I'm sure you soon find your site with Yahoo.
Every Search Engine has its own algorithms to rank a page on the web, their is some criteria that can match but not whole. Google use different criteria and Yahoo also use other.
yahoo loves good onsite optimization and content while google preferes quality backlink so u need to consider both things when want to rank in same at same time
First of all, PR are far different from SERP. Having good PR doesnt means having good SERP, too (or vice versa). Second, Google and Yahoo has different and own, unique algorithm, so dont wonder if you rank well in other SE and not on the other one.
Everyone is telling that yahoo dont have PR, but have webrank [0-10 ranking], which is different than PR. But where i can check my site with webrank????? I need to check my site. i've search a lots of site but i found nothing as solution.
