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.

Do URLs with canonical tags get indexed by Google?
Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop. Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

Will Google crawl and rank our ReactJS website content?
We have 250+ products dynamically inserted and sorted on our site daily (more specifically our homepage... yes, it's a long page). Our dev team would like to explore rendering the page server-side using ReactJS. We currently use a CDN to cache all the content, which of course we would like to continue using. SO... will Google be able to crawl that content? We've read some articles with different ideas (including prerendering): http://andrewhfarmer.com/react-seo/

http://www.seoskeptic.com/json-ld-big-day-at-google/ If we were to only load the schema important to the page (like product title, image, price, description, etc.) from the server and then let the client render the remaining content (comments, suggested products, etc.), would that go against best practices? It seems like that might be seen as showing the googlebot 1 version and showing the site visitor a different (more complete) version.0 -

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 /feed URLs from Google's Index
Hey everyone, I have an issue with RSS /feed URLs being indexed by Google for some of our Wordpress sites. Have a look at this Google query, and click to show omitted search results. You'll see we have 500+ /feed URLs indexed by Google, for our many category pages/etc. Here is one of the example URLs: http://www.howdesign.com/design-creativity/fonts-typography/letterforms/attachment/gilhelveticatrade/feed/. Based on this content/code of the XML page, it looks like Wordpress is generating these: <generator>http://wordpress.org/?v=3.5.2</generator> Any idea how to get them out of Google's index without 301 redirecting them? We need the Wordpress-generated RSS feeds to work for various uses. My first two thoughts are trying to work with our Development team to see if we can get a "noindex" meta robots tag on the pages, by they are dynamically-generated pages...so I'm not sure if that will be possible. Or, perhaps we can add a "feed" paramater to GWT "URL Parameters" section...but I don't want to limit Google from crawling these again...I figure I need Google to crawl them and see some code that says to get the pages out of their index...and THEN not crawl the pages anymore. I don't think the "Remove URL" feature in GWT will work, since that tool only removes URLs from the search results, not the actual Google index. FWIW, this site is using the Yoast plugin. We set every page type to "noindex" except for the homepage, Posts, Pages and Categories. We have other sites on Yoast that do not have any /feed URLs indexed by Google at all. Side note, the /robots.txt file was previously blocking crawling of the /feed URLs on this site, which is why you'll see that note in the Google SERPs when you click on the query link given in the first paragraph.

Ranking on google.com.au but not google.com
Hi there, we (www.refundfx.com.au) rank on google.com.au for some keywords that we target, but we do not rank at all on google.com, is that because we only use a .com.au domain and not a .com domain? We are an Australian company but our customers come from all over the world so we don't want to miss out on the google.com searches. Any help in this regard is appreciated. Thanks.

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.
