    Hello,

    On my WP site I use WP Total Cache and I've activated the option to use a CDN where the load is divided into 4 different CDNs.

    cdn1.sitename.com
    cdn2 etc...

    Now when I do a google search site:mysite.com those cdns subdomains appear in the search and I wonder if that'll give me a dub content penalty by google?

    Anyone knows about this or how I can noindex those cdns?

    Thanks!

    CDN involves indeed a duplicate content except if it is used for different langage otherwise i don't see any advantage to have a CDN, even though you may reduce the loading time for UK users assuming it is in English but it doesn't worth to get penalized over such a detail.

    You may want to remove it and to redo a fast indexing process toward your website.

    You are using the CDN option wrong.
    There shouldn't be any duplicate content - CDN does not create duplicate content.

    The point of a CDN is to serve files from a different server, usually one that's geolocated closer to the website visitor (and to save bandwidth).
    Having the files come from multiple places on your own server, (although it would slightly speed up load time due to simultaneous loading) is really not how a CDN was meant to be used.

    The only reason I can think of to use CDN split on your own server is if you are separating your static files from your cookie domain, but even then you would want to put all of your static files on ONE subdomain.
    But this shouldn't cause duplicate content either - the html should always be served from the main domain - CDN is only for support files like images, css or javascript.

    If you need/want a CDN, you should look at amazon's CDN which is really cheap or at MAXCDN which has a deal for a terabyte of bandwidth for $40 (I use maxcdn personally, and I love it)
