      I have 2 sites hosted with Blue Host and was told to put the robots.txt in the root folder and just use the one robots.txt for both sites. Is this right? It seems wrong. I want to block certain things on one site.

      Thanks for the help,

      Rena

        Hi Rena. Yes, if both sites are separate domains that you want to use in different ways, then you should place a different robots.txt file in each domain root so that they're accessible at xyz.com/robots.txt and abc.com/robots.txt.  Cheers!

          Hi Rena,

          You technically can do that, but it's not recommended - for the exact reason you state above. More often than not, 2 sites aren't going to have the same set of disallow rules.

          Additionally, you should also be using robots.txt files to direct search engines to your XML sitemap, and if you're sharing a robots file, then you can't specify 2 different sitemaps on 2 different domains.

            Each individual website (and some subdomains if you add them) needs a unique robots.txt file. You can copy the same file and use it again and again on each site, but each one needs a robots.txt file.

              Disallow wildcard match in Robots.txt

              This is in my robots.txt file, does anyone know what this is supposed to accomplish, it doesn't appear to be blocking URLs with question marks Disallow: /?crawler=1
              Disallow: /?mobile=1 Thank you

              Robots.txt & meta noindex--site still shows up on Google Search

              I have set up my robots.txt like this: User-agent: *
              Disallow: / and I have this meta tag in my on a Wordpress site, set up with SEO Yoast name="robots" content="noindex,follow"/> I did "Fetch as Google" on my Google Search Console My website is still showing up in the search results and it says this: "A description for this result is not available because of this site's robots.txt" This site has not shown up for years and now it is ranking above my site that I want to rank for this keyword. How do I get Google to ignore this site? This seems really weird and I'm confused how a site with little content, that has not been updated for years can rank higher than a site that is constantly updated and improved.

              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!

              Does my "spam" site affect my other sites on the same IP?

              I have a link directory called Liberty Resource Directory. It's the main site on my dedicated IP, all my other sites are Addon domains on top of it. While exploring the new MOZ spam ranking I saw that LRD (Liberty Resource Directory) has a spam score of 9/17 and that Google penalizes 71% of sites with a similar score. Fair enough, thin content, bunch of follow links (there's over 2,000 links by now), no problem. That site isn't for Google, it's for me. Question, does that site (and linking to my own sites on it) negatively affect my other sites on the same IP? If so, by how much? Does a simple noindex fix that potential issues? Bonus: How does one go about going through hundreds of pages with thousands of links, built with raw, plain text HTML to change things to nofollow? =/

              Should I block Map pages with robots.txt?

              Hello, I have a website that was started in 1999. On the website I have map pages for each of the offices listed on my site, for which there are about 120. Each of the 120 maps is in a whole separate html page. There is no content in the page other than the map. I know all of the offices love having the map pages so I don't want to remove the pages. So, my question is would these pages with no real content be hurting the rankings of the other pages on our site? Therefore, should I block the pages with my robots.txt? Would I also have to remove these pages (in webmaster tools?) from Google for blocking by robots.txt to really work? I appreciate your feedback, 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!

              301 redirects & merging two sites into one

              We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces. For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one. What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had? I am not sure how this works or if there is a best practice way to do this. Thanks Gareth
