When SEOs disavow links, they tell search engines not to count the links for rankings. Some people say that disavowing a link is the same as putting a No Follow tag on it, but based on our experience this is an over-simplification.
To disavow links with Google, one needs to create a disavow file in a specific format and upload it to the Google Search Console (GSC), formerly known as Google Webmaster Tools (GWT).
A disavow file can be created and maintained inside LRT and the Link Detox components to improve efficiency and avoid mistakes in this very error-prone process.
To disavow links with Bing, one needs to add every link or domain to a disavow user interface in Bing Webmaster Tools (BWT).
Disavowing happens on three possible scopes
- Root Domain Level - i.e. everything under *.spamdomain.com
- Host Level / Sub Domain Level - i.e. every link from blog.spamdomain.com
- Page Level- i.e. all links from a specific page https://blog.spamdomain.com/linkfarm.html
Because mistakes often happen, good and helpful links are often found to be disavowed. The reasons are a multitude, but the effects are always negative - a drop in rankings.
Therefore it is strongly recommended to re-visit the list of disavowed links in a disavow file audit to re-avow or un-disavow the formerly bad links.
