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.
