My total count of indexed url decreases in bing, please let me know any bing algorithm is rolling out?
Have you made any change in your website lately? It can also happen when you website have duplicate contents. If you are worried about the indexes then you can manually submit your urls. You can submit a maximum of ten urls per day.
Yahoo and Bing update their index at a snail's pace compared to Google. I have had websites that took over a month to get indexed. Generally, the number of indexed pages on bing/yahoo are far less than Google. According to bing, they tend to be picky when it comes to indexing pages and homepage should get indexed first before any other page.
