Orphan Duplicate is created as Subdomain in Google Search

[rkdc]

We noticed that some of our results on google for the blog are also come up with subdomain that is not linked from anywhere on the website.

For example:

SUBDOMAIN1.website.com/blog/content.html -> it redirects to website.com/blog/content.html

SUBDOMAIN1 is not linked anywhere on the website.

How did the google find it in the first place?

Why does it still keep it in the search results?

How do you get rid of it?

Hi there,

301 it to the original and noindex it. That should do the trick for both users & google.

Cheers

It's been 301 all the time (at least few years), we have rewrite if doesn't match the domain pattern. That subdomain only shows up in the DNS records.
