Yahoo Keyword Density Analysis Comparison to Google Research by goRank.com compiled on Feb 17 comparing "keyword density elements of Yahoo's new algorithm with Google's algorithm".
Found that Yahoo seemed to have a preference for more words on a page and more frequent exact word matches. Google's lower figure for keyword density (2% vs Yahoo at 2.8%) may because it does semantic word matching.
Both engines care about keyword density in the title. (Google = 16.9% and Yahoo = 19.6%).
Link text is a factor too, where Yahoo may prefer less text and better matches in the links.
Bolding could make a small difference. Yahoo likes it.
