It's been a while since this was asked, yet I find it really interesting, as a lot of people only focus on other search engines(mostly Google) without considering there's a huge audience to be reached via Bing.
As far as I know, every search engine has it's own algorithms and it's not always so simple to optimize in each one. The best you can do is try to be genuine with the content you make, and check the guidelines provided by bing to do the best practices.
Just look for "bing webmaster-guidelines"
I hope this answer finds you well, best of lucks!
