      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.

        You appear to have the MX sub-domain also set up as an A record.

        If you have a mac / linux you can run the command: host aspmx3.googlemail.com.sullivansolarpower.com

        You get the result aspmx3.googlemail.com.sullivansolarpower.com has address 72.10.48.198

        Where you should get the result "not found".

        I think you want to delete the A record (though check the documentation of your email provider first). You should only need them set up as MX records and shouldn't need the A record.

        You've done the right thing by setting up the redirect - which should mean that the pages drop out of the index and those links disappear. (Note that there is also an https error on the aspmx3 sub-domain - but given that you don't actually want it, I don't suppose that matters that much).

        Hope that helps.

          I did not explain the problem thoroughly.  The problem is, the link does not actually exist anywhere.  To make a very long story short.  There was an issue with server configuration for a period of a couple months.  During that time, an unknown number of non-existent subdomains got indexed.   Basically, if anyone had a typo in the subdomain when accessing our site, it would get cached and if Google crawled our site before we cleared the cache, the typo subdomain would get indexed.  Over a period of a couple months, many bad subdomains were accidentally created and indexed by Google.  We do not have any way of finding a comprehensive list of all of them.  This problem has been resolved so we are not getting new bad subdomains created and indexed, but the damage has been done.

          The way our site is setup currently, any attempt to reach our site with any subdomain other than "www" gets redirected to "www.sullivan..."  Also, any nonsecure protocol gets resolved to https://

          The actual problem, simply put is this:  Google has an index which includes some number of unknown, non existent subdomains.  We need to get rid of them and cannot figure out how.

          Example:  Copy and paste the following into google and search it:

          site:aspmx3.googlemail.com.sullivansolarpower.com

          Google will return two results.  If you click on either, it resolves to the "https://www. version of the page.

          I know it is confusing, but does that make sense? I have searched everywhere, but the reason this happened was because of a perfect storm of server configuration issues and I cannot find anyone else who has had the same problem.

          If it were one or two bad subdomains, we would just put them into search console and then get "remove URL" for the entire subdomain.  But it is not 1 or 2.  It is at least 10 that I know of and could be hundreds for all I know.

          Does anyone have any ideas?  Any and all would be welcome.

          Thank you.

            You should find the locations of those links and correct them to point to the proper URL. I find that Screaming Frog's crawl is the easiest for this, you can find every link and see where they are located.

              Google not Indexing images on CDN.

              My URL is: https://bit.ly/2hWAApQ We have set up a CDN on our own domain: https://bit.ly/2KspW3C We have a main xml sitemap: https://bit.ly/2rd2jEb and https://bit.ly/2JMu7GB is one the sub sitemaps with images listed within. The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: https://bit.ly/2FAWJjk. Yet, GWT still reports none of our images on the CDN are indexed. I ve followed all the steps and still none of the images are being indexed. My problem seems similar to this ticket https://bit.ly/2FzUnBl but however different because we don't have a separate image sitemap but instead have listed image urls within the sitemaps itself. Can anyone help please? I will promptly respond to any queries. Thanks

              Removed Subdomain Sites Still in Google Index

              Hey guys, I've got kind of a strange situation going on and I can't seem to find it addressed anywhere.  I have a site that at one point had several development sites set up at subdomains.  Those sites have since launched on their own domains, but the subdomain sites are still showing up in the Google index.  However, if you look at the cached version of pages on these non-existent subdomains, it lists the NEW url, not the dev one in the little blurb that says "This is Google's cached version of www.correcturl.com."  Clearly Google recognizes that the content resides at the new location, so how come the old pages are still in the index?  Attempting to visit one of them gives a "Server Not Found" error, so they are definitely gone. This is happening to a couple of sites, one that was launched over a year ago so it doesn't appear to be a "wait and see" solution. Any suggestions would be a huge help.  Thanks!!

              Google indexing despite robots.txt block

              Hi This subdomain has about 4'000 URLs indexed in Google, although it's blocked via robots.txt: https://www.google.com/search?safe=off&q=site%3Awww1.swisscom.ch&oq=site%3Awww1.swisscom.ch This has been the case for almost a year now, and it does not look like Google tends to respect the blocking in http://www1.swisscom.ch/robots.txt Any clues why this is or what I could do to resolve it? Thanks!

              Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?

              Dear all, starting with my .htaccess file: RewriteEngine On
              RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
              RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html 
              RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
              2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

              Does google use the wayback machine to determine the age of a site?

              I have a site that I had removed from the wayback machine because I didn't want old versions to show. However I noticed that in many seo tools the site now always shows a domain age of zero instead of 6 years ago when I registered it. My question is what do the actual search engines use to determine age when they factor it into the ranking algorithm? By having it removed from the wayback machine, does that make the search engines think the site is brand new? Thanks

              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.

              How do I redirect index.html to the root / ?

              The site I've inherited had operated on index.html at one point, and now uses index.php for the home page, which goes to the / page. The index.html was lost in migrating server hosts. How do I redirect the index.html to the / page? I've tried different options that keep giving ending up with the same 404 error. I tried a redirect from index.html to index.php which ended in an infinite loop. Because the index.html no longer exists in the root, should I created it and then add a redirect to it? Can I avoid this by editing the .htaccess? Any help is appreciated, thanks in advance!
