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.

Google tries to index non existing language URLs. Why?
Hi, I am working for a SAAS client. He uses two different language versions by using two different subdomains.
Technical SEO | | TheHecksler
de.domain.com/company for german and en.domain.com for english. Many thousands URLs has been indexed correctly. But Google Search Console tries to index URLs which were never existing before and are still not existing. de.domain.com**/en/company
en.domain.com/de/**company ... and an thousand more using the /en/ or /de/ in between. We never use this variant and calling these URLs will throw up a 404 Page correctly (but with wrong respond code - we`re fixing that 😉 ). But Google tries to index these kind of URLs again and again. And, I couldnt find any source of these URLs. No Website is using this as an out going link, etc.
We do see in our logfiles, that a Screaming Frog Installation and moz.com w opensiteexplorer were trying to access this earlier. My Question: How does Google comes up with that? From where did they get these URLs, that (to our knowledge) never existed? Any ideas? Thanks 🙂0 -

Will Google Recrawl an Indexed URL Which is No Longer Internally Linked?
We accidentally introduced Google to our incomplete site. The end result: thousands of pages indexed which return nothing but a "Sorry, no results" page. I know there are many ways to go about this, but the sheer number of pages makes it frustrating. Ideally, in the interim, I'd love to 404 the offending pages and allow Google to recrawl them, realize they're dead, and begin removing them from the index. Unfortunately, we've removed the initial internal links that lead to this premature indexation from our site. So my question is, will Google revisit these pages based on their own records (as in, this page is indexed, let's go check it out again!), or will they only revisit them by following along a current site structure? We are signed up with WMT if that helps.

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

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 not pulling my favicon
Several sites use Google favicon to load favicons instead of loading it from the Website itself. Our favicon is not being pulled from our site correctly, instead it shows the default "world" image. https://plus.google.com/_/favicon?domain=www.example.com Is the address to pull a favicon. When I post on G+ or see other sites that use that service to pull favicons ours isn't displaying, despite it shows up in Chrome, Firefox, IE, etc and we have the correct meta in all pages of our site. Any idea why is this happening? Or how to "ping" Google to update that?

What to do with 302 redirects being indexed
Hi there, Our site's forums include permalinks that for some reason uses an intermediary URL that 302 redirects to the URL with the permalink anchor. For example: http://en.tradimo.com/learn/chart-analysis/time-frames/ In the comments, there is a permalink to the following URL; en.tradimo.com/co/50c450005f2b949e3200001b/ (there is no content here, and never has been). This URL 302 redirects to the following final URL: http://en.tradimo.com/learn/chart-analysis/time-frames/?offset=0&limit=20#50c450005f2b949e3200001b The problem is, Google is indexing the redirect URL (en.tradimo.com/co/50c450005f2b949e3200001b/) and showing duplicate content even though we are using the nofollow tag on these links. Ideally, we would directly use the last link rather than redirecting. Alternatively, I'd say a 301 redirect would be preferable. But if both aren't available, is there a way to get these pages out of the index? Is the canonical tag the best way? I really wish I could just add /co/ to the robots.txt file, but I think they would still be in the index, right? Thanks for your help!

Dynamically-generated .PDF files, instead of normal pages, indexed by and ranking in Google
Hi, I come across a tough problem. I am working on an online-store website which contains the functionlaity of viewing products details in .PDF format (by the way, the website is built on Joomla CMS), now when I search my site's name in Google, the SERP simply displays my .PDF files in the first couple positions (shown in normal .PDF files format: [PDF]...)and I cannot find the normal pages there on SERP #1 unless I search the full site domain in Google. I really don't want this! Would you please tell me how to figure the problem out and solve it. I can actually remove the corresponding component (Virtuemart) that are in charge of generating the .PDF files. Now I am trying to redirect all the .PDF pages ranking in Google to a 404 page and remove the functionality, I plan to regenerate a sitemap of my site and submit it to Google, will it be working for me? I really appreciate that if you could help solve this problem. Thanks very much. Sincerely SEOmoz Pro Member
