Hope friend you will help me regards my issue. Actually today I was checking my site back links in webmaster tool.
https://www.google.com/webmasters/ www.yourdomain.com Traffic Links to Your Site
3 days back webmaster tool was showing my 55000 back links for my site and today it is showing only 4000 back links, which is very shocking for me. Where my all back link gone while I didn’t use “disavow links” tool?????
