I run about 15 different sites Google and Yahoo has slight variations up or down but 5 weeks ago all my rankings which ranged from #1 to 50 were dropped by Bing I thought it was just an update but this is week 5 now and my keywords have not gone back to where they were or even close anyone have an explanation?
Nope, in fact I think is starting to filter out spam better and that's why our rankings are going up.
I still haven't figured out to optimize my site for Bing. I do well in both Yahoo and Google... I did better when it was live.com!
