      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.

              Does anyone know the linking of hashtags on Wix sites does it negatively or postively impact SEO. It is coming up as an error in site crawls 'Pages with 404 errors' Anyone got any experience please?

              Does anyone know the linking of hashtags on Wix sites does it negatively or positively impact SEO.  It is coming up as an error in site crawls 'Pages with 404 errors'  Anyone got any experience please? For example at the bottom of this blog post https://www.poppyandperle.com/post/face-painting-a-global-language the hashtags are linked, but they don't go to a page, they go to search results of all other blogs using that hashtag.  Seems a bit of a strange approach to me.

              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?

              Mobile site ranking instead of/as well as desktop site in desktop SERPS

              I have just noticed that the mobile version of my site is sometimes ranking in the desktop serps either instead of as well as the desktop site. It is not something that I have noticed in the past as it doesn't happen with the keywords that I track, which are highly competitive. It is happening for results that include our brand name, e.g '[brand name][search term]'. The mobile site is served with mobile optimised content from another URL. e.g wwww.domain.com/productpage redirects to m.domain.com/productpage for mobile. Sometimes I am only seen the mobile URL in the desktop SERPS, other times I am seeing both the desktop and mobile URL for the same product. My understanding is that the mobile URL should not be ranking at all in desktop SERPS, could we be being penalised for either bad redirects or duplicate content? Any ideas as to how I could further diagnose and solve the problem if you do believe that it could be harming rankings?

              Are robots.txt wildcards still valid? If so, what is the proper syntax for setting this up?

              I've got several URL's that I need to disallow in my robots.txt file. For example, I've got several documents that I don't want indexed and filters that are getting flagged as duplicate content. Rather than typing in thousands of URL's I was hoping that wildcards were still valid.

              Oh no googlebot can not access my robots.txt file

              I just receive a n error message from google webmaster Wonder it was something to do with Yoast plugin. Could somebody help me with troubleshooting this? Here's original message Over the last 24 hours, Googlebot encountered 189 errors while attempting to access your robots.txt. To ensure that we didn't crawl any pages listed in that file, we postponed our crawl. Your site's overall robots.txt error rate is 100.0%. Recommended action If the site error rate is 100%: Using a web browser, attempt to access http://www.soobumimphotography.com//robots.txt. If you are able to access it from your browser, then your site may be configured to deny access to googlebot. Check the configuration of your firewall and site to ensure that you are not denying access to googlebot. If your robots.txt is a static page, verify that your web service has proper permissions to access the file. If your robots.txt is dynamically generated, verify that the scripts that generate the robots.txt are properly configured and have permission to run. Check the logs for your website to see if your scripts are failing, and if so attempt to diagnose the cause of the failure. If the site error rate is less than 100%: Using Webmaster Tools, find a day with a high error rate and examine the logs for your web server for that day. Look for errors accessing robots.txt in the logs for that day and fix the causes of those errors. The most likely explanation is that your site is overloaded. Contact your hosting provider and discuss reconfiguring your web server or adding more resources to your website. After you think you've fixed the problem, use Fetch as Google to fetch http://www.soobumimphotography.com//robots.txt to verify that Googlebot can properly access your site.

              Does Bing ignore robots txt files?

              Bonjour from "Its a miracle is not raining" Wetherby Uk 🙂 Ok here goes... Why despite a robots text file excluding indexing to site http://lewispr.netconstruct-preview.co.uk/ is the site url being indexed in Bing bit not Google? Does bing ignore robots text files or is there something missing from http://lewispr.netconstruct-preview.co.uk/robots.txt I need to add to stop bing indexing a preview site as illustrated below. http://i216.photobucket.com/albums/cc53/zymurgy_bucket/preview-bing-indexed.jpg Any insights welcome 🙂

              Bing rank drop off for multiple sites

              Hi Mozzers, Seeing some wacky stuff going on on some sites I manage. In more than a few, the ranking on bing has dropped basically overnight from page one spots to not being found on the first 100 positions. Anyone else seeing similar results? Some of the sites are fairly new, some have been around for ages, some are wordpress, some are not. I've been searching for some news of a big change on bing, but keep reading about bing dropping the thin sites during black friday. In one example, I had the site set up in BWT for a while, and had a look at the data. The reports show that the pages are crawled, the index summary shows pages indexed, and there seems to be no crawl errors, but rankings are absolutely gone. Also, I can't see the sites in bing if I search "site:example.com" in bing. Here's 2 examples, the first would make sense since it's pretty thin as I havent added much content yet: http://homewindowtint.org but this one doesn't make sense to me. Sure there's a few errors, but to be dropped like a rock seems weird http://www.ahmedandsukaram.com
