How to remove my cdn sub domins on Google search result?

[Godad]

A few months ago I moved all my Wordpress images into a sub domain. After I purchased CDN service, I again moved that images to my root domain. I added User-agent: * Disallow: / to my CDN domain.

But now, when I perform site search on the Google, I found that my CDN sub domains are indexed by the Google. I think this will make duplicate content issue. I already hit by the Panguin. How do I remove these search results on Google?

Should I add my cdn domain to webmaster tools to request URL removal request?

Problem is, If I use cdn.mydomain.com it shows my www.mydomain.com.

My blog:- http://goo.gl/58Utt

site search result:- http://goo.gl/ElNwc

Blocking with robots.txt doesn't remove pages/files from the search engines, it only prevents them from crawling the subdomain. If they already crawled those resources, as they have in your case, the robots.txt will just block them from visiting it again, but will not remove them.

What you should do is authenticate the subdomain with webmaster tools, and then remove the subdomain via the url removal tool, as you asked. This is the way to go about it.

To verify the subdomain, there are multiple options, including via your host, or you can modify the dns to prove you own the subdomain - it really depends on your setup and what you need to do.

But to remove these results permanently, with your robots.txt block, you should do it via the URL removal tool.

Good luck,

Mark
