Good rankings with Google but difficulties to enter on Top 50 with Bing and Yahoo?

[OptimizedGroup]

Hi guys, I'm facing this problem with some websites that I'm trying to optimize for the search engines. I've worked on a good SEO on Page and I've had not so many difficulties to get good ranking results on Google. The problem is that I'm not having any result with Yahoo and Bing, even if I've sent the sitemap to the Bing Webmaster Toll and I'm keeping under control the possible crawling errors both on Google and Bing Webmaster Tool. Can someone please help me with an explanation?

Nothing special.. rankings are determined through very similar factors: quality, relevant links and content.

Make sure all of your pages target a specific keyword, keep building links and producing relevant content and you will break into top 50 rankings in time.
