Why Bing suddenly dropped index of website?

[John-Smith]

Does it make any sense? SEO Company should know the reasons. If the best companies don't know then how we can understand what's going on!

It's caused by 5 reasons:
1. The page isn't loading properly
2. You changed your URL recently but don't notice it
3. Duplicate content issue
4. Time out page too much time and Bing sign your page weaker and not index them.
5. Check your robot.txt if you set up to prevent bot to index your site.
