          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.

                      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!

                      301 Redirect non existant pages

                      Hi I have 100's of URL's appearing in Search Console for example: ?p=1_1 These go to on to 5_200 etc.. I have tried to do htaccess and the mod rewrite is on as I can redirect directories to the root i.e RewriteRule ^web_example(.*)$ /$1 [R=301,N,L] However I have tried all kinds of variations to redirect ?p= and either it doesn't work at all or it crashes the website. Can anyone point me in the right direction to fix this.

                      Duplicate Content Issue WWW and Non WWW

                      One of my sites got hit with duplicate content a while ago because Google seemed to be considering hhtp, https, www, and non ww versions of the site all different sites. We thought we fixed it, but for some reason https://www and just https:// are giving us duplicate content again. I can't seem to figure out why it keeps doing this. The url is https://bandsonabudget.com if any of you want to see if you can figure out why I am still having this issue.

                      Robots.txt on http vs. https

                      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...

                      Will Adding Publish Date at end of Page Title for Blog posts Hurt SEO?

                      I'd like to be able to easily track blog posts by month but in Google reports when you set a date range obviously older blog post still appear and with amount of blog posts we generate without seeing the date in the title it's not obvious what was published and when it was published. For example if a Blog Title was "/dangers-of-sharing-KM-knowledge-01-11-15 would it hurt SEO? The reason is I'd like to have a quick way to know how new posts do each month compared to older content

                      Google insists robots.txt is blocking... but it isn't.

                      I recently launched a new website.  During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files.  You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap.  These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are  able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

                      Googlebot does not obey robots.txt disallow

                      Hi Mozzers! We are trying to get Googlebot to steer away from our internal search results pages by adding a parameter "nocrawl=1" to facet/filter links and then robots.txt disallow all URLs containing that parameter. We implemented this late august and since that, the GWMT message "Googlebot found an extremely high number of URLs on your site", stopped coming. But today we received yet another. The weird thing is that Google gives many of our nowadays robots.txt disallowed URLs as examples of URLs that may cause us problems. What could be the reason? Best regards, Martin

                      Handling 301s: Multiple pages to a single page (consolidation)

                      Been scouring the interwebs and haven't found much information on redirecting two serparate pages to a single new page.  Here is what it boils down to: Let's say a website has two pages, both with good page authority of products that are becoming fazed out.  The products, Widget A and Widget B, are still popular search terms, but they are being combined into ONE product, Widget C.  While Widget A and Widget B STILL have plenty to do with Widget C, Widget C is now the new page, the main focus page, and the page you want everyone to see and Google to recognize. Now, do I 301 Widget A and Widget B pages to Widget C, ALTHOUGH Widgets A and B previously had nothing to do with one another?   (Remember, we want to try and keep some of that authority the two page have had.) OR do we keep Widget A and Widget B pages "alive", take them off the main navigation, and then put a "disclaimer" on the pages announcing they are now part of Widget C and link to Widget C? OR Should Widgets A and B page be canonicalized to Widget C? Again, keep in mind, widgets A and B previously were not similar, but NOW they are and result in Widget C. (If you are confused, we can provide a REAL work example of what we are talkinga about, but decided to not be specific to our industry for this.) Appreciate any and all thoughts on this.
