      We recently changed our domain from http to https. When a user enters any URL on http, there is an global 301 redirect to the same page on https.

      I cannot find instructions about what to do with robots.txt. Now that https is the canonical version, should I block the http-Version with robots.txt?

      Strangely, I cannot find a single ressource about this...

          Good point with the backlinks! Currently, both robots.txt files are open and google does not seem to have canonicalization problems so far. So it makes sense to leave it this way anyways... Thanks Thomas!

            Absolutely not GWT will handel all of it think about backlinks both https:// & http:// urls you will not want to lose the flow of link juice that you would cut off

            Remake robost.txt with

            http://www.internetmarketingninjas.com/seo-tools/robots-txt-generator/

            But use https:// for the xml sitemap.

              Multiple robots.txt files on server

              Hi! I have previously hired a developer to put up my site and noticed afterwards that he did not know much about SEO. This lead me to starting to learn myself and applying some changes step by step. One of the things I am currently doing is inserting sitemap reference in robots.txt file (which was not there before). But just now when I wanted to upload the file via FTP to my server I found multiple ones - in different sizes - and I dont know what to do with them? Can I remove them? I have downloaded and opened them and they seem to be 2 textfiles and 2 dupplicates. Names: robots.txt (original dupplicate)
              robots.txt-Original (original)
              robots.txt-NEW (other content)
              robots.txt-Working (other content dupplicate) Would really appreciate help and expertise suggestions. Thanks!

              DNS vs IIS redirection

              I'm working on a project where a site has gone through a rebrand and is therefore also moving to a new domain name. Some pages have been merged on the new site so it's not a lift and shift job and so I'm writing up a redirect plan. Their IT dept have asked if we want redirects done by DNS redirect or IIS redirect. Which one will allow us to have redirects on a page level and not a domain level? I think IIS may be the right route but would love your thoughts on this please.

              Which Sitemap to keep - Http or https (or both)

              Hi, Just finished upgrading my site to the ssl version (like so many other webmasters now that it may be a ranking factor). FIxed all links, CDN links are now secure, etc and 301 Redirected all pages from http to https. Changed property in Google Analytics from http to https and added https version in Webmaster Tools. So far, so good. Now the question is should I add the https version of the sitemap in the new HTTPS site in webmasters or retain the existing http one? Ideally switching over completely to https version by adding a new sitemap would make more sense as the http version of the sitemap would anyways now be re-directed to HTTPS. But the last thing i can is to get penalized for duplicate content. Could you please suggest as I am still a rookie in this department. If I should add the https sitemap version in the new site, should i delete the old http one or no harm retaining it.

              WordPress - How to stop both http:// and https:// pages being indexed?

              Just published a static page 2 days ago on WordPress site but noticed that Google has indexed both http:// and https:// url's. Usually I only get http:// indexed though. Could anyone please explain why this may have happened and how I can fix? Thanks!

              Robots.txt Sitemap with Relative Path

              Hi Everyone, In robots.txt, can the sitemap be indicated with a relative path? I'm trying to roll out a robots file to ~200 websites, and they all have the same relative path for a sitemap but each is hosted on its own domain. Basically I'm trying to avoid needing to create 200 different robots.txt files just to change the domain. If I do need to do that, though, is there an easier way than just trudging through it?
