I recently noticed that yahoo slurp is twice active as compared to googlebot and MSN bot. Also the sites are cached fastest as compared to google. Whats on other peoples stats??? Here is stat from one of my sites its similar across all others too
Similar situation on my sites with bots crawling, but visitors still mostly come from Google as my rankings are better on it than on its competitors.
How old is your site? I noticed that when a site is new, Googlebot is much more active. Then, with time, Yahoo! slurp takes over.
Its about year old. Couple of months ago it was MSN leading the chart but its next to nowhere now....
Yahoo indexes my site more than google also, and my site is only 4 months old. I think Yahoo's spider is faster/more active or something of the sort.
I am curious yahoo slurp crawl my site for three month but no any traffic from yahoo search engine It may be yahoo slurp no efficiency
