I think forums posting, social bookmarking on high page rank with the LSI keywords will be much better If you want to optimize your primary keyword.
Normally, if you do your seo for google and then yahoo, forgot about the bing. Because there is so much competition on Google and to some extent on yahoo.. that you can't look back to bing. Simply, you can submit sitemap of your site, using Bing tools for adding your website to bing and etc etc..
Until recently, I never paid much attention to my Bing traffic because it was so minimal. However, to my surprise, I suddenly noticed a 300% jump in Bing organic traffic over past month. Can't think of much that changed, though I did tweak some meta title tags to contain more keywords. Seems they like that better than just back links. I also should point out that I have a higher conversion rate with Bing....perhaps be cause target market is older and less tech savvy? Just speculating.
Doing normal SEO process improves the keywords ranking in Bing. For quick index, use Bing search for your keywords and better to use in your website.
The market share is far too small to worry about this. I have noticed in the past that some of the older seo tactics that no longer work for Google tend to do well in bing and yahoo. Wouldn't waste my time though.
submit your article on bing webmaster tools first. create a sitemap for your site's Url. add meta data language if you use blogger, it aims to avoid any mistakes in your blog.
I have noticed that if my meta tag title and description are closer to the search keywords, bing reacts more favorably in the SEPS. While various other on-page / off-page optimizations are required, I have pages with page authority 1, ranking on #4 on bing and yahoo.
There is no specific method of SEO just for bing. You can do it like general SEO method just submit your website on bing and get update with it. You can also submit your article and blog on bing.
For ranking in Bing SERPs the webmaster should use Ethical SEO techniques and start link building. For indexing you have to submit and search in Bing.
Sometimes i really feel Bing has a automatic ranking procedure. Most of things you do for Google will be effective for Bing also.
