      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.

              Crawl solutions for landing pages that don't contain a robots.txt file?

              My site (www.nomader.com) is currently built on Instapage, which does not offer the ability to add a robots.txt file. I plan to migrate to a Shopify site in the coming months, but for now the Instapage site is my primary website. In the interim, would you suggest that I manually request a Google crawl through the search console tool? If so, how often? Any other suggestions for countering this Meta Noindex issue?

              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

              Help Setting Up 301 Redirects from Coldfusion Site to Wordpress Site.

              I have created a new website and need to redirect all of the previous pages to the new one. The old website was built in coldfusion and the new site is built in wordpress. One of the pages I'm trying to redirect is www.norriseal.com/products.cfm to http://norrisealwellmark.com/products/. This is what I have in my .htaccess file <ifmodule mod_rewrite.c="">Options +FollowSymlinks
              RewriteEngine On
              RewriteBase /
              Redirect 301 /products.cfm http://norrisealwellmark.com/products/</ifmodule> The result of this redirect is http://norrisealwellmark.com/products.cfm How do I prevent the .cfm from appending to the destination URL?

              Lost with conical, nofollow noindex. Not sure how to use it on a dyanmic php site with multiple region select options

              I have a site with multiple regions the main page after a region is selected is login.php but the regions are defined by ?rid=11 , 12, etc. These are being picked up as duplicate content but they are all different regions. As i hired external php coders to develop most of the site I am scared to start meddling with any of the raw code and would like some advise on how to not show these as duplicate content. should i use noindex nofollow or connical? if Connical how do i set it up on the main login.php page? p.s. i am an extreme nube to seo

              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?

              Delete old site but redirect domain to a new domain and site

              I just have a quick query and I have a feeling about what the answer is so just wanted to see what you guys thought... Basically I am working on a client site. This client has a few other websites that are divisions of their company. However these divisions/websites are no longer used. They are wanting to delete the websites but redirect the domains to their name main website. They believe this will pass on SEO benefits as these old division sites are old and have a good PR and history. I'm unsure for DEFINITE, which way is correct?

              Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains

              Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's  pointing to the same IP address as our "preferred domain:"  for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP.  This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain.  We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w.  This seemed to help resolve the issue and moved hundreds of pages off the index.  However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain.  When you click on the link, it does redirect to the same page but under the preferred domain.  So the redirect is working and has been confirmed as 301.  But for some reason Google continues to crawl our site and index under this incorrect domains.  Why is this? Is there a setting we are missing?   These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing.  Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
