Of course it matters. But don't expect great things. Bing has a tiny market share. Its still a market share... but it is a tiny market share.If your site is at the top of Bing, does that matter? I just checked my site is at the top of Bing and on page 5 of Google. I'm getting 10-20 visitors per day. I think they're all from Bing.
Any free keyword research tool for Bing that shows you searches per month etc.? Same keyword has 9000+ exact US searches on Google. I wanna find out the searches on Bing.
