          There are two robots.txt pages. One for www version and another for non-www version though I have moved to the non-www version.

              Hi ramb,

              Short answer: No, it won't affect your ability to rank in Google. Unless both sites (non-www and www version) compete for the same search term and one of them isn't blocked in the correspondent robots.txt file.

              If you can, make sure to have a redirection rule so as everything in the non-www goes to the www.
              It bugs me why aren't you redirecting the complete non-www to the www version.
              Two possibilities come to my mind:

              1. You can't redirect the whole non-www due to some app or technical need. 
                In this case, both versions, if accessible to Google, will be treated as different sites. Thus, you must be sure that both robots file are correct for the given subdomain.
              2. You have a separate website, which contains different content from the www version (this usually happens with subdomains with different page types, such as products.abc.com and categories.abc.com)
                In this case, please be sure that you know what you want to be blocked and have each robots.txt file in their subdomain.

              Keep in mind that Robots file only controls where you don't want googlebot to access in the public version of your website. When a certain page or group of pages are blocked in robots.txt, google won't access them anymore thus not knowing if that page has what it needs to rank for any given search term. Google might rank lower and users will see a note in search results, leading to a lower CTR.

              Hope it helps.
              Best Luck.
              Gaston

                Are you redirecting everything on www to non-www? If so, you don't really need a robots.txt to be served for the www subdomain. Google will ignore the original robots.txt file if it is given a 301 anyway.

                  Hi Gatson

                  Thank you for your response. Currently, www version of the site is redirected to non-www version, which is the primary(or root) domain.

                  But the problem is, I have 2 robots.txt files running for the same site. i.e. same robots.txt file loads on both www and non-www version. (Example https://www.abc.com/robots.txt and https://abc.com/robots.txt).

                  Does it affect my site's SEO ??
                  Should I redirect www-version of the file to non-www version?
                  Your feedback will be highly appreciated.

                  Thank you,

                  R.

                    Hi ramb,

                    It's totally fine to have different robots.txt files for different subdomains.
                    Thus said, http://domain.com and http://www.domain.com are different subdomains. Consider the one with non-www as the full root domain.

                    In case it is needed, here you have Google's official resource about robots.txt: 
                    Learn about Robots.txt file - Search Console help

                    Hope it helps.
                    Best luck.

                      Best Practice for www and non www

                      How is the best way to handle all the different variations of a website in terms of www | non www | http | https? In Google Search Console, I have all 4 versions and I have selected a preference. In Open Site Explorer I can see that the www and non www versions are treated differently with one group of links pointing to each version of the same page. This gives a different PA score. eg. http://mydomain.com DA 25 PA 35 http://www.mydomain.com DA 19 PA 21 Each version of the home page having it's only set of links and scores. Should I try and "consolidate" all the scores into one page? Should I set up redirects to my preferred version of the website? Thanks in advance

                      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!

                      Is sitemap required on my robots.txt?

                      Hi, I know that linking your sitemap from your robots.txt file is a good practice. Ok, but... may I just send my sitemap to search console and forget about adding ti to my robots.txt? That's my situation: 1 multilang platform which means... ... 2 set of pages. One for each lang, of course But my CMS (magento) only allows me to have 1 robots.txt file So, again: may I have a robots.txt file woth no sitemap AND not suffering any potential SEO loss? Thanks in advance, Juan Vicente Mañanas Abad

                      Non-Existent Parent Pages SEO Impact

                      Hello, I'm working with a client that is creating a new site. They currently are using the following URL structure: http://clientname.com/products/furry-cat-muffins/ But the landing page for the directory /products/ does not actually have any content. They have a similar issue for the /about/ directory where the menu actually sends you to /about/our-story/ instead of /about/. Does it hurt SEO to have the URL structure set up in this way and also does it make sense to create 301 redirects from /about/ to /about/our-story/?

                      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!

                      Robots.txt and Multiple Sitemaps

                      Hello, I have a hopefully simple question but I wanted to ask to get a "second opinion" on what to do in this situation. I am working on a clients robots.txt and we have multiple sitemaps. Using yoast I have my sitemap_index.xml and I also have a sitemap-image.xml I do put them in google and bing by hand but wanted to have it added into the robots.txt for insurance. So my question is, when having multiple sitemaps called out on a robots.txt file does it matter if one is before the other? From my reading it looks like you can have multiple sitemaps called out, but I wasn't sure the best practice when writing it up in the file. Example: User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /wp-admin/ Disallow: /wp-content/plugins/ Sitemap: http://sitename.com/sitemap_index.xml Sitemap: http://sitename.com/sitemap-image.xml Thanks a ton for the feedback, I really appreciate it! :) J

                      Block Domain in robots.txt

                      Hi. We had some URLs that were indexed in Google from a www1-subdomain. We have now disabled the URLs (returning a 404 - for other reasons we cannot do a redirect from www1 to www) and blocked via robots.txt. But the amount of indexed pages keeps increasing (for 2 weeks now). Unfortunately, I cannot install Webmaster Tools for this subdomain to tell Google to back off... Any ideas why this could be and whether it's normal? I can send you more domain infos by personal message if you want to have a look at it.

                      OK to block /js/ folder using robots.txt?

                      I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1
                      http://www.discoverafrica.com/js/jquery.cookie.js?v=1.1
                      http://www.discoverafrica.com/js/global.js?v=1.2
                      http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
                      http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?
