How Do I delete unwanted backlink from my Blog profile?
 

I want to delete unwanted backlink from my blog. I have seen 8.2 million external backlink on my blog from one website whick is huge and hampering my Blog. Is there any way I can delete these backlinks from my blog.

Its not easy to delete the millions of backlinks.. but as you said all backlinks are from one site so you can take help of disavow tool.. All you need is to create a disavow file and mention reason for disavowing the site.. Then submit that file through your webmaster account by using disavow tool.. Once google will accept your request, all your links will present there but crawler will not crawl those links...

Using the google webmaster tool you can delete unwanted backlinks.

Then submit that file through your webmaster account by using disavow tool.. Once google will accept your request, all your links will present there but crawler will not crawl those links.

Deleting all of them will require too much time, You can easily disavow them (as Google will not read them) by using google webmaster tool.
