Welcome to the Q&A Forum

Awesome, thank you!

I have a sub domain that isn't even on our own site but it's resulting in a lot of errors in Moz for duplicate content, as shown here: http://cl.ly/1R081v0K0e2N. Would this affect our ranking or is it simply just errors within Moz?

What measures could I take to make sure that Moz or Google doesn't associate our site with these errors? Would I have to noindex in the htaccess file for the sub domain?

Hi there,

Thanks for your reply. I'm not sure how feasible it is to redirect all of those urls. I know I could use regex but I just terminated the server that admin.site.com lived on so I can't access a robots.txt file anymore. Could I simply do a generic redirect admin.site.com -> site.com?

The subdomain was the same site and domain.

Thanks.

The other thing I should note is that these site links do not show in Google when searching for the topic. I'm only seeing reported back links because the admin.site.com subdomain was blocked from Google crawling it for search results. Not sure if that makes a difference.

It says I can only demote 100 links, I need to demote upwards of 40,000 since the admin.site.com basically mirrored the actual site.

Now I'm a little confused.

I took the old site down, so I can use a robots.txt file there anymore.

So how can I disallow the entire admin subdomain and stop reporting back links?

Thanks

Hi there. Thanks for your response.

The pages exist on the new site, but the subdomain should have never been indexed. I noticed the back links in Google Console initially then confirmed with SEO Power Suite.

Basically we had site.com, then created a brand new site and migrated content over to newsite.com with 301 redirects from the old site. Then we wanted to keep the old site up for reference so we put it at admin.site.com. That is where all the 40,000 back links were coming from, admin.site.com, the old site.

There is no reason for us to redirect admin.site.com since the original articles were properly redirected. I guess however some how when the old site was taken down, Google must have indexed it still at the subdomain and counted those as backlinks.

I just started doing an SEO audit and noticed I have 40,000 some odd back links from an OLD version of our site that has been moved to a subdomain. The back links are for articles that already exist on our main site. I don't think Google is picking it up as duplicate content because that site isn't being crawled anymore. Could this hurt us SEO wise? I plan on removing the site, but how long after it's been removed should those back links disappear?
