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.

Google Published Date - Does Google Lie?
Here's the scenario. I create a page called "ABC" and it gets published and found by Google lets say on the 13th of April. on the 15th (or 14th) i decide to update the URL, page Title, and content. (Redirect old URL to new URL as well) Will Google still show this page as being published on the 13th? or would it update the publish date according to the new URL?

Website is not indexed in Google
Hi Guys, I have a problem with a website from a customer. His website is not indexed in Google (except for the homepage). I could not find anything that can possibly be the cause. I already checked the robots.txt, sitemap, and plugins on the website. In the HTML code i also couldn't find anything which makes indexing harder than usual. This is the website i am talking about: http://www.xxxx.nl/ (Dutch) The only thing that i am guessing now is the Google sandbox, but even that is quite unlikely. I hope you guys discover something i could not find! Thanks in advance 🙂

Unnecessary pages getting indexed in Google for my blog
I have a blog dapazze.com and I am suffering from a problem for a long time. I found out that Google have indexed hundreds of replytocom links and images attachment pages for my blog. I had to remove these pages manually using the URL removal tool. I had used "Disallow: ?replytocom" in my robots.txt, but Google disobeyed it. After that, I removed the parameter from my blog completely using the SEO by Yoast plugin. But now I see that Google has again started indexing these links even after they are not present in my blog (I use #comment). Google have also indexed many of my admin and plugin pages, whereas they are disallowed in my robots.txt file. Have a look at my robots.txt file here: http://dapazze.com/robots.txt Please help me out to solve this problem permanently?

Will a "blog=example "parameter at the end of my URLs affect google's crawling them?
For example, I'm wondering if www.example.com/blog/blog-post is better than www.example.com/blog/blog-post?blog=example? I'm currently using the www.example.com/blog/blog-post?blog=example structure as our canonical page for content. I'm also wondering, if the parameter doesn't affect crawling, if it would hurt rankings in any way. Thanks!

Is this against google rules
Hi i am wanting to know if this is against google rules. I am building a website which will have lots of different sections and i wanted to know if you were allowed to have a new domain name pointing to a section of the site. so for example if i had a site with a domain name of manchester and then i wanted a section of the site to be called www.manchester.com/complimentary health I want to know if to help with traffic to the site and to have a better domain name, if it was allowed to have a new domain name pointing to that section of the site which could be called www.complimentaryhealth.com and have that pointing to the section. would love to hear your thoughts on this

De-indexing thin content & Panda--any advantage to immediate de-indexing?
We added the nonidex, follow tag to our site about a week ago on several hundred URLs, and they are still in Google's index. I know de-indexing takes time, but I am wondering if having those URLs in the index will continue to "pandalize" the site. Would it be better to use the URL removal request? Or, should we just wait for the noindex tags to remove the URLs from the index?

Why do I see dramatic differences in impressions between Google Webmaster Tools and Google Insights for Search?
Has anyone else noticed discrepancies between these tools? Take keyword A and keyword B. I've literally seen situations where A has 3 or 4 times the traffic as B in Google Webmaster Tools, but half the traffic of B in Google Insights for Search. What might be the reason for this discrepancy?
