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.

Should I "no-index" two exact pages on Google results?
Hello everyone, I recently started a new wordpress website and created a static homepage. I noticed that on Google search results, there are two different URLs landing on same content page. I've attached an image to explain what I saw. Should I "no-index" the page url? Google url.JPG In this picture, the first result is the homepage and I try to rank for that page. The last result is landing on same content with different URL. So, should I no-index last result as shown in image?

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 -
How to stop google from indexing specific sections of a page?
I'm currently trying to find a way to stop googlebot from indexing specific areas of a page, long ago Yahoo search created this tag class=”robots-nocontent” and I'm trying to see if there is a similar manner for google or if they have adopted the same tag? Any help would be much appreciated.

Google indexing despite robots.txt block
Hi This subdomain has about 4'000 URLs indexed in Google, although it's blocked via robots.txt: https://www.google.com/search?safe=off&q=site%3Awww1.swisscom.ch&oq=site%3Awww1.swisscom.ch This has been the case for almost a year now, and it does not look like Google tends to respect the blocking in http://www1.swisscom.ch/robots.txt Any clues why this is or what I could do to resolve it? Thanks!

How to fix Google index after fixing site infected with malware.
Hi All Upgraded a Joomla site for a customer a couple of months ago that was infected with malware (it wasn't flagged as infected by google). Site is fine now but still noticing search queries for "cheap adobe" etc with links to http://domain.com/index.php?vc=201&Cheap_Adobe_Acrobat_xi in web master tools (about 50 in total). These url's redirect back to home page and seem to be remaining in the index (I think Joomla is doing this automatically) Firstly, what sort of effect would these be having on on their rankings? Would they be seen by google as duplicate content for the homepage (moz doesn't report them as such as there are no internal links). Secondly what's my best plan of attack to fix them. Should I setup 404's for them and then submit them to google? Will resubmitting the site to the index fix things? Would appreciate any advice or suggestions on the ramifications of this and how I should fix it. Regards, Ian

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

Why is my blog disappearing from Google index?
My Google blogger blog is about 10 months old. In that time i have worked really hard with adding unique content, building relationships with other bloggers in the same niche, and done some inbound marketing. 2 weeks ago I updated the template to something cleaner, with a little more "wordpress" feel to it. This means i've messed about with the code a lot in these weeks, adding social buttons etc. The problem is that from some point late last week thurs/fri my pages started disappearing from Googles index. I have checked webmaster tools and have no manual actions. My link profile is pretty clean as its a new site, and i have manually checked every piece of content published for plagiarism etc. So what is going on? Did i break my blog? Or is something else amiss? Impressions are down 96% comparing Nov 1-5th to previous 5 days. site is here: http://bit.ly/174beVm Thanks for any help in advance.

Pages removed from Google index?
Hi All, I had around 2,300 pages in the google index until a week ago. The index removed a load and left me with 152 submitted, 152 indexed? I have just re-submitted my sitemap and will wait to see what happens. Any idea why it has done this? I have seen a drop in my rankings since. Thanks
