Anyway, I updated my disavow list but my question is this:
On the Google Search Console disavow page, when I select my domain property it states that “Domain properties are not supported at this time.” So, I have a choice of four versions of my website: HTTP and HTTPS and with and without www. So, my question is: which one do I upload the disavow list to? I have been using the https://www one. Is that the one to use or do I have to upload the disavow list to all four each time?
It is common for sites to pick up many links from unsavoury sources, and the more legitimate links to the site, or the more prominent the site, the greater the chance of any such link occurring is. So high value sites may have millions of such links, and moderate value sites may have thousands of them. None of them having any overall effect.
If a disavow makes you feel happier, and you’d otherwise lose effectiveness worrying, then by all means do a disavow, but understand that it is completely unnecessary, and the time could certainly have been spent more productively.
