I too am seeing more hits from Bing than google on a UK focused site. This presents me with a huge dilemma. The site still does v well on bing / yahoo but has been 'penguined' by google.
I was going to launch on a new domain but now Bing seems to be gaining traction and their referrals convert so much better (45% better conversion from bing / yahoo referrals) so I really don't want to lose that valuable traffic trying to get back into g's goodbooks (with no guarantee of success and none of the stability that Bing provides and my business needs).
I'm thinking about blocking Google from the original site and blocking Bing / Yahoo from the new site, a site for each SE, how tedious. Anyone tried this with success?
