Example: I own domain1.com I made 2themoney.com an add-on domain with the host. In AHREF's on an internal page on 2themoney.com/article1, it is showing one page backlinking to it. 2themoney.domain1 dot.com/deep-page SO I can get to2themoney.com/deep-page from this link or 2themoney.domain1 dot.com/deep-page I know this is fundamentally wrong on shared hosting plans. So what is going on here or how can I fix it? I have Useragent: disallow Disallow: / I have had a canonical tag for years on the header. Thanks
