We're getting a ton of 404 errors in our GWT but they aren't actually pages on our site.
Before you tell me this doesn't matter, note: they are real pages and they do exist... just not on our site.
We're operating on a third party system. There's some central software/mechanism operating behind all the websites using this system. Basically, like, there are the following websites:
- central-server.com (their sales website, basically)
- user36633.central-server.com (not meant to be publicly accessed, is a duplicate)
- some-other-user.central-server.com (same as above)
So basically... on user36633.com, we're getting errors for some-other-user.com.
My question: will this negatively affect our site? I found this 2011 Webmaster Central blog that says pages which do not exist do not harm your site. However -- these pages do exist...
