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.

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 google crawls images and which url shows as source?
Hi, I noticed that some websites host their images to a different url than the one their actually website is hosted but in the end google link to the one that the site is hosted. Here is an example: This is a page of a hotel in booking.com: http://www.booking.com/hotel/us/harrah-s-caesars-palace.en-gb.html When I try a search for this hotel in google images it shows up one of the images of the slideshow. When I click on the image on Google search, if I choose the Visit Page button it links to the url above but the actual image is located in a totally different url: http://r-ec.bstatic.com/images/hotel/840x460/135/13526198.jpg My question is can you host your images to one site but show it to another site and in the end google will lead to the second one?

Vanity URLs are being indexed in Google
We are currently using vanity URLs to track offline marketing, the vanity URL is structured as www.clientdomain.com/publication, this URL then is 302 redirected to the actual URL on the website not a custom landing page. The resulting redirected URL looks like: www.clientdomain.com/xyzpage?utm_source=print&utm_medium=print&utm_campaign=printcampaign. We have started to notice that some of the vanity URLs are being indexed in Google search. To prevent this from happening should we be using a 301 redirect instead of a 302 and will the Google index ignore the utm parameters in the URL that is being 301 redirect to? If not, any suggestions on how to handle? Thanks,

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

How does Google Crawl Multi-Regional Sites?
I've been reading up on this on Webmaster Tools but just wanted to see if anyone could explain it a bit better. I have a website which is going live soon which is going to be set up to redirect to a localised URL based on the IP address i.e. NZ IP ranges will go to .co.nz, Aus IP addresses would go to .com.au and then USA or other non-specified IP addresses will go to the .com address. There is a single CMS installation for the website. Does this impact the way in which Google is able to search the site? Will all domains be crawled or just one? Any help would be great - thanks!
