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 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?

Site indexed by Google, but (almost) never gets impressions
Hi there, I have a question that I wasn't able to give it a reasonable answer yet, so I'm going to trust on all of you. Basically a site has all its pages indexed by Google (I verified with site:sitename.com) and it also has great and unique content. All on-page grades are A with absolutely no negative factors at all. However its pages do not get impressions almost at all. Of course I didn't expect it to be on page 1 since it has been launched on Dec, 1st, but it looks like Google is ignoring (or giving it bad scores) for some reason. Only things that can contribute to that could be: domain privacy on the domain, redirect from the www to the subdomain we use (we did this because it will be a multi-language site, so we'll assign to each country a subdomain), recency (it has been put online on Dec 1st and the domain is just a couple of months old). Or maybe because we blocked crawlers for a few days before the launch? Exactly a few days before Dec 1st. What do you think? What could be the reason for that? Thanks guys!

Google stopped crawling my site. Everybody is stumped.
This has stumped the Wordpress staff and people in the Google Webmasters forum. We are in Google News (have been for years), and so new posts are crawled immediately. On Feb 17-18 Crawl Stats dropped 85%, and new posts were no longer indexed (not appearing on News or search). Data highlighter attempts return "This URL could not be found in Google's index." No manual actions by Google. No changes to the website; no custom CSS. No Site Errors or new URL errors. No sitemap problems (resubmitting didn't help). We're on wordpress.com, so no odd code. We can see the robot.txt file. Other search engines can see us, as can social media websites. Older posts still index, but loss of News is a big hit. Also, I think overall Google referrals are dropping. We can Fetch the URL for a new post, and many hours later it appears on Google and News, and we can then use Data Highlighter. It's now 6 days and no recovery. Everybody is stumped. Any ideas? I just joined, so this might be the wrong venue. If so, apologies.

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.

Instant Indexing
I've been working on a site for a while now, methodically building content and building trust and authority. Lately I've noticed that anything I publish there appears to be instantly indexed by Google, which surprises me. I haven't had this happen before so I'm curious. I'd be interested to hear the experience of others.

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.
