CDN Being Crawled and Indexed by Google
-
I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases.
It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt?
Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL.
Thanks!

It sounds like you got a hold of the problem.
Verify the subdomains in WMT
Block the CDN subdomains with robots.txt
Request site removal in WMT for the subdomains
make the canonicals absolute
Keep the blocked subdomains in WMT, when you log in you will see a message by the subdomains saying "Critical issue with your site" which is just telling you that the site is blocked.. I like to keep it in there so I can see it's still blocked.

Site indexed by Google, but (almost) never gets impressions
Hi there, I have a question that I wasn't able to give it a reasonable answer yet, so I'm going to trust on all of you. Basically a site has all its pages indexed by Google (I verified with site:sitename.com) and it also has great and unique content. All on-page grades are A with absolutely no negative factors at all. However its pages do not get impressions almost at all. Of course I didn't expect it to be on page 1 since it has been launched on Dec, 1st, but it looks like Google is ignoring (or giving it bad scores) for some reason. Only things that can contribute to that could be: domain privacy on the domain, redirect from the www to the subdomain we use (we did this because it will be a multi-language site, so we'll assign to each country a subdomain), recency (it has been put online on Dec 1st and the domain is just a couple of months old). Or maybe because we blocked crawlers for a few days before the launch? Exactly a few days before Dec 1st. What do you think? What could be the reason for that? Thanks guys!

Removed Subdomain Sites Still in Google Index
Hey guys, I've got kind of a strange situation going on and I can't seem to find it addressed anywhere. I have a site that at one point had several development sites set up at subdomains. Those sites have since launched on their own domains, but the subdomain sites are still showing up in the Google index. However, if you look at the cached version of pages on these non-existent subdomains, it lists the NEW url, not the dev one in the little blurb that says "This is Google's cached version of www.correcturl.com." Clearly Google recognizes that the content resides at the new location, so how come the old pages are still in the index? Attempting to visit one of them gives a "Server Not Found" error, so they are definitely gone. This is happening to a couple of sites, one that was launched over a year ago so it doesn't appear to be a "wait and see" solution. Any suggestions would be a huge help. Thanks!!

No index on subdomains
Hi, We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain? The main domain is vitally important - it is just that sub domain I need to hide. Many thanks

Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
Dear all, starting with my .htaccess file: RewriteEngine On
Technical SEO | | inlinear
RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

Does Google pass link juice a page receives if the URL parameter specifies content and has the Crawl setting in Webmaster Tools set to NO?
The page in question receives a lot of quality traffic but is only relevant to a small percent of my users. I want to keep the link juice received from this page but I do not want it to appear in the SERPs.

Does Google index XML files?
Does Google or other search engines include XML files in their index? More specifically, I am wondering how Google knows the difference between an xml filetype and an RSS feed.
