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.

URLs dropping from index (Crawled, currently not indexed)
I've noticed that some of our URLs have recently dropped completely out of Google's index. When carrying out a URL inspection in GSC, it comes up with 'Crawled, currently not indexed'. Strangely, I've also noticed that under referring page it says 'None detected', which is definitely not the case. I wonder if it could be something to do with the following? https://www.seroundtable.com/google-ranking-index-drop-30192.html - It seems to be a bug affecting quite a few people. Here are a few examples of the URLs that have gone missing: https://www.ihasco.co.uk/courses/detail/sexual-harassment-awareness-training https://www.ihasco.co.uk/courses/detail/conflict-resolution-training https://www.ihasco.co.uk/courses/detail/prevent-duty-training Any help here would be massively appreciated!

Does Google index internal anchors as separate pages?
Hi, Back in September, I added a function that sets an anchor on each subheading (h[2-6]) and creates a Table of content that links to each of those anchors. These anchors did show up in the SERPs as JumpTo Links. Fine. Back then I also changed the canonicals to a slightly different structur and meanwhile there was some massive increase in the number of indexed pages - WAY over the top - which has since been fixed by removing (410) a complete section of the site. However ... there are still ~34.000 pages indexed to what really are more like 4.000 plus (all properly canonicalised). Naturally I am wondering, what google thinks it is indexing. The number is just way of and quite inexplainable. So I was wondering: Does Google save JumpTo links as unique pages? Also, does anybody know any method of actually getting all the pages in the google index? (Not actually existing sites via Screaming Frog etc, but actual pages in the index - all methods I found sadly do not work.) Finally: Does somebody have any other explanation for the incongruency in indexed vs. actual pages? Thanks for your replies! Nico

Blocked URL parameters can still be crawled and indexed by google?
Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

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

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

Google is indexing my directories
I'm sure this has been asked before, but I was looking at all of Google's results for my site and I found dozens of results for directories such as: Index of /scouting/blog/wp-includes/js/swfupload/plugins Obviously I don't want those indexed. How do I prevent Google from indexing those? Also, it only seems to be doing it with Wordpress, not any of the directories on my main site. (We have a wordpress blog, which is only a portion of the site)
