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.

How long does Google takes to re-index title tags?
Hi, We have carried out changes in our website title tags. However, when I search for these pages on Google, I still see the old title tags in the search results. Is there any way to speed this process up? Thanks

How to check if an individual page is indexed by Google?
So my understanding is that you can use site: [page url without http] to check if a page is indexed by Google, is this 100% reliable though? Just recently Ive worked on a few pages that have not shown up when Ive checked them using site: but they do show up when using info: and also show their cached versions, also the rest of the site and pages above it (the url I was checking was quite deep) are indexed just fine. What does this mean? thank you p.s I do not have WMT or GA access for these sites

Fake Links indexing in google
Hello everyone, I have an interesting situation occurring here, and hoping maybe someone here has seen something of this nature or be able to offer some sort of advice. So, we recently installed a wordpress to a subdomain for our business and have been blogging through it. We added the google webmaster tools meta tag and I've noticed an increase in 404 links. I brought this up to or server admin, and he verified that there were a lot of ip's pinging our server looking for these links that don't exist. We've combed through our server files and nothing seems to be compromised. Today, we noticed that when you do site:ourdomain.com into google the subdomain with wordpress shows hundreds of these fake links, that when you visit them, return a 404 page. Just curious if anyone has seen anything like this, what it may be, how we can stop it, could it negatively impact us in anyway? Should we even worry about it? Here's the link to the google results. https://www.google.com/search?q=site%3Amshowells.com&oq=site%3A&aqs=chrome.0.69i59j69i57j69i58.1905j0j1&sourceid=chrome&es_sm=91&ie=UTF-8 (odd links show up on pages 2-3+)

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.

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 google index my IP URL
hi guys, a question please. if site:112.65.247.14 , you can see google index our website IP address, this could duplicate with our darwinmarketing.com content pages. i am not quite sure why google index my IP pages while index domain pages, i understand this could because of backlink, internal link and etc, but i don't see obvious issues there, also i have submit request to google team to remove ip address index, but seems no luck. Please do you have any other suggestion on this? i was trying to do change of address setting in Google Webmaster Tools, but didn't allow as it said "Restricted to root level domains only", any ideas? Thank you! boson
