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 Not Indexing Pages (Wordpress)
Hello, recently I started noticing that google is not indexing our new pages or our new blog posts. We are simply getting a "Discovered - Currently Not Indexed" message on all new pages. When I click "Request Indexing" is takes a few days, but eventually it does get indexed and is on Google. This is very strange, as our website has been around since the late 90's and the quality of the new content is neither duplicate nor "low quality". We started noticing this happening around February. We also do not have many pages - maybe 500 maximum? I have looked at all the obvious answers (allowing for indexing, etc.), but just can't seem to pinpoint a reason why. Has anyone had this happen recently? It is getting very annoying having to manually go in and request indexing for every page and makes me think there may be some underlying issues with the website that should be fixed.

Vanity URLs are being indexed in Google
We are currently using vanity URLs to track offline marketing, the vanity URL is structured as www.clientdomain.com/publication, this URL then is 302 redirected to the actual URL on the website not a custom landing page. The resulting redirected URL looks like: www.clientdomain.com/xyzpage?utm_source=print&utm_medium=print&utm_campaign=printcampaign. We have started to notice that some of the vanity URLs are being indexed in Google search. To prevent this from happening should we be using a 301 redirect instead of a 302 and will the Google index ignore the utm parameters in the URL that is being 301 redirect to? If not, any suggestions on how to handle? Thanks,

How To Cleanup the Google Index After a Website Has Been HACKED
We have a client whose website was hacked, and some troll created thousands of viagra pages, which were all indexed by Google. See the screenshot for an example. The site has been cleaned up completely, but I wanted to know if anyone can weigh in on how we can cleanup the Google index. Are there extra steps we should take? So far we have gone into webmaster tools and submitted a new site map. ^802D799E5372F02797BE19290D8987F3E248DCA6656F8D9BF6^pimgpsh_fullsize_distr.png

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+)

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

How Does Google's "index" find the location of pages in the "page directory" to return?
This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched. These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory". The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls. Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

Google not pulling my favicon
Several sites use Google favicon to load favicons instead of loading it from the Website itself. Our favicon is not being pulled from our site correctly, instead it shows the default "world" image. https://plus.google.com/_/favicon?domain=www.example.com Is the address to pull a favicon. When I post on G+ or see other sites that use that service to pull favicons ours isn't displaying, despite it shows up in Chrome, Firefox, IE, etc and we have the correct meta in all pages of our site. Any idea why is this happening? Or how to "ping" Google to update that?

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.
