A partner of mine owns a Website that has had history of being penalized in Yahoo. Years ago these penalties were reconciled, however just recently started to show signs of penalization again.
Her question was whether these penalties would carry over to Bing. Currently she is not seeing any signs of penalization on Bing, in fact traffic has been trending upward. Would Yahoo's "Core search technology" that is supposedly being integrated into Bing carry with it some of these penalties?
