It always comes back to grinding out the backlinks and articles. Following the fundamental steps will get you there every time.
I think the first step would be to submit ur site's sitemap to Bing Webmaster Tools. I agree with other members that Bing pays a lot of attention to the url of the domain.
Firstly, content is unique. Unique and quality content helps you earn trust and foster relationships with your readers. Secondly, your website must only try to get links from websites with high Page Rank (5-9)
Worry about Google alone. It kind of sucks that Google has such complete domination over the search market, but I get literally 1/30th of my search traffic from Bing and Yahoo COMBINED. Any kind of effort tailored toward trying to rank higher in Bing or Yahoo is a waste IMHO. If you are Russian or Chinese, however, Google is not the end-all-be-all (restricted in China and not very popular in Russia). Food for thought!
Always remember these things: Content is King Quality Links Website Directories By this means, you'll have higher rank in Bing.
If you want to rank high in bing and other search engine's then do the on page and off page work of your site. It will helps you to increase your site page rank.
