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.

Should search pages be indexed?
Hey guys, I've always believed that search pages should be no-indexed but now I'm wondering if there is an argument to index them? Appreciate any thoughts!

Desktop & Mobile XML Sitemap Submitted But Only Desktop Sitemap Indexed On Google Search Console
Hi! The Problem We have submitted to GSC a sitemap index. Within that index there are 4 XML Sitemaps. Including one for the desktop site and one for the mobile site. The desktop sitemap has 3300 URLs, of which Google has indexed (according to GSC) 3,000 (approx). The mobile sitemap has 1,000 URLs of which Google has indexed 74 of them. The pages are crawlable, the site structure is logical. And performing a Landing Page URL search (showing only Google/Organic source/medium) on Google Analytics I can see that hundreds of those mobile URLs are being landed on. A search on mobile for a longtail keyword from a (randomly selected) page shows a result in the SERPs for the mobile page that judging by GSC has not been indexed. Could this be because we have recently added rel=alternate tags on our desktop pages (and of course corresponding canonical ones on mobile). Would Google then 'not index' rel=alternate page versions? Thanks for any input on this one. PmHmG

Google Indexed a version of my site w/ MX record subdomain
We're doing a site audit and found "internal" links to a page in search console that appear to be from a subdomain of our site based on our MX record. We use Google Mail internally. The links ultimately redirect to our correct preferred subdomain "www", but I am concerned as to why this is happening and if it can have any negative SEO implications. Example of one of the links: Links aspmx3.googlemail.com.sullivansolarpower.com/about/solar-power-blog/daniel-sullivan/renewable-energy-and-electric-cars-are-not-political-footballs I did a site operator search, site:aspmx3.googlemail.com.sullivansolarpower.com on google and it returns several results.

Staging site and "live" site have both been indexed by Google
While creating a site we forgot to password protect the staging site while it was being built. Now that the site has been moved to the new domain, it has come to my attention that both the staging site (site.staging.com) and the "live" site (site.com) are both being indexed. What is the best way to solve this problem? I was thinking about adding a 301 redirect from the staging site to the live site via HTACCESS. Any recommendations?

Does Google pass link juice a page receives if the URL parameter specifies content and has the Crawl setting in Webmaster Tools set to NO?
The page in question receives a lot of quality traffic but is only relevant to a small percent of my users. I want to keep the link juice received from this page but I do not want it to appear in the SERPs.
