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 -
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

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

Is Google caching date same as crawling/indexing date?
If a site is cached on say 9 oct 2012 doesn't that also mean that Google crawled it on same date ? And indexed it on same date?

Why are Google search results different if you are log'd into Google or not?
I get different results when I'm log'd into my Google account associated with my website than if I'm not. The same country is occurring. So how can I rely on the google results I'm seeing? For instance my site is page 1 with the improvements I made based on SEOMOZ if I'm log'd in. Yet I'm not on the first 25 pages if I'm not logged in.

How to get Google to index another page
Hi, I will try to make my question clear, although it is a bit complex. For my site the most important keyword is "Insurance" or at least the danish variation of this. My problem is that Google are'nt indexing my frontpage on this, but are indexing a subpage - www.mydomain.dk/insurance instead of www.mydomain.dk. My link bulding will be to subpages and to my main domain, but i wont be able to get that many links to www.mydomain.dk/insurance. So im interested in making my frontpage the page that is my main page for the keyword insurance, but without just blowing the traffic im getting from the subpage at the moment. Is there any solutions to do this? Thanks in advance.

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
