I have the same problem with
www.business-idea.com site.
I got over 700 hits per day from Slurp. The logs show that Slurp has been coming from 1794 different IP addresses last 3 months. I could hardly imagine that there are so many data centres. Or did I miss something?
In fact, I got 7 times more hits from Slurp than from real Yahoo traffic. This situation lasts some 2 months. Two months ago, the site was #2 for "business ideas" key words, now it is #26.
Is Yahoo reindexing already 2 months or is there something wrong with the Slurp robot?
