Should we disallow links from websites with wild card duplications like AAA.domain.command CCC .domain.com? And does many links from websites without any traffic and back links, can that affect our rankings?
So I’m not 100% sure what you mean with wildcard domains. I have sometimes seen sites that are more kind of like directory sites, where the sub-domain is kind of a category, and there are millions of subdomains there that kind of result in a really complicated structure to setup. And if you feel that links from a site like that are causing you problems, maybe you’ve bought links there in the past and you want them removed, then you can use a domain listing in the disavowed file, and just say everything from this domain. And that will automatically include all of the subdomains that are there as well. On the other hand, if you just want to disavow certain subdomains, then you can use a domain entry and say domain, colon, and the specific subdomain. And then we’ll take that into account like that.
