The latst round of tests from the Search Engine Quality Report shows Yahoo strengthening their lead in providing the most relevant search results. MSN's performance was plagued by difficulties filtering duplicate content, while Google seemed to struggle in determining relevancy. See the raw data at Search Engine Test Results - Round Three.
I agree with yahoo's performance. I am also feeling some difference. Probably i also posted it somewhere in forums
Yahoo has done a pretty good job at making sure Google dosn't walk all over it all of the time. MSN just has issues. I don't know how else to put it. And I think that at times Google is so big they don't know what to do with themselves, but they would never tell us that.
