What is disavowing?
Disavowing means that you are asking Google to not consider (ie. give credit to) a link back to your site. You would want to do this if it is a low quality link, because a lot of low quality links can trigger a Google penalty, which leads to lower rankings and traffic.
The process of disavowing with Monitor Backlinks is two steps:
- Disavow the bad link in Monitor Backlinks
- Submit the disavow file to Google.

Disavowing is not asking a site to remove a link
This is different than asking a site to remove a link.
Google advises that you should first ask a site owner to remove a link before disavowing. In practice, most requests are unsuccessful, which makes disavowing necessary anyway.
Disavowing is not deleting a link in Monitor Backlinks
Deleting a link in Monitor Backlinks just removes it from the Monitor Backlinks interface. It doesn't send any information to Google, and therefore doesn't have any effect on disavowing.
