my site was not yet index in bing, i don't know the problem..it ranks well in both google and yahoo but not in bing..is it true that bing has now different algorithm?
Also make sure that you go to Bing and type "add url to Bing" in the search engine, that way the link will come up so that you can submit your home page there. That is a great way to get it added as quickly as possible, it works for me.
Create a Bing webmaster tools account, add your site to your profile and submit a sitemap. Bing is rather slow at indexing sites and pages. Where google might have 40,000 pages indexed for a site, bing might only have 5,000 - 10,000 pages. People complain about how slow google is to see changes. Well, from what I have seen, bing is a lot slower then google.
Based on my experience Bing Indexed the sites very quickly rather than Yahoo... Yahoo indexed so slowly...
Bing need some more time to index your site. you can proceed your link building work, it will be indexed automatically by bing.
submit your site to Bing first or by using bing webmaster tool, then its help to index your site better.
