This simple program makes backlinks queried from ahref ready for Google Search Console. See footnote 1 for more information.
It can be used to clean up thousands of malicious backlinks.

Note: this program was written at the request of a friend of mine. I don't have an expertise for SEO or Google Search Console, and I'm not a pro in these topics.

Install this program:

go get github.com/SeanTolstoyevski/rawlink

rawlink --help

Output:

Usage of rawlink:
  -i string
        Location of the file to be read (default "backlink.txt")
  -o string
        Name of the file to be written (default "fixed_backlinks.txt")

Imagine you have an e-commerce site. Your malicious competitors may send your page URL to sites that produce obscene/adult content. This affects your page's rank on Google.

Example of Ahref output:

domain:adultsitedomainname.extension/x/y/z/post-name

The program converts to:

domain:adultsitedomainname.extension

You can then tell Google "reject these domains".
