Matt says that you can use the disavow tool to share links with Google you don’t want to be associated with. ie. in case you want to remove links from a particular domain, you can do so using the disavow tool.
If your blog has been hit by negative SEO and there are a lot of domain that you want to remove you many have to upload more than one file or you may want to upload files at a later date.
Here is a tip from Matt: He says that if you want to upload a new file, there is no need to delete the old file. All you need to do is just upload the new file.
There have been instances where SEO professionals and internet marketers have deleted the old files while uploading the new one. This confuses the Google algo, its best not to confuse Google while fixing site issues.
Have you used the disavow tool ? What has been you’re experience ?
