I have 90k backlinks from 3 websites. On a subdomain, I have catalogs and my clients have a link on their site in the header to these catalogs. This means that they have in all their pages a link to the catalogs from my subdomain.Should I reserve a new domain to host these catalogs? Or I do not have to worry because they are on a subdomain?If I have more than 90000 backlinks to a subdomain, will this affect the main website?Can Google penalize my website because of the backlinks to a subdomain?
How do thousands of backlinks to my subdomains affect SEO?
