I have a forum web site which has about 30,000 pages indexed in Google which Google bot comes to now and again, but for a while now yahoo have been all over my site, I am talking Yahoo! Slurp Spider viewing a thread about 75 times at the same time all the time however I only have 500 pages index in yahoo and no traffic from them or rank at all for any keywords, I can't understand why its the other way around with google. Do you think they are re looking at my site to re rank or do you think that I should block the search engine in robots.txt
