      Hi guys!

      I keep reading conflicting information on this and it's left me a little unsure. Am I right in thinking that a website with a subdomain of shop.sitetitle.com will share the same robots.txt file as the root domain?

        That's about as comprehensive an answer as I could have hoped for. Thanks Ryan, really appreciated.

          Mostly no.  I say 'mostly' because a lot of times when you look at a site using www and no-www if both of those work they're almost always pulling files from the same location (hence the warnings around duplicate content), so both www.domain.com/robots.txt and domain.com/robots.txt are going to work.  This is the dominant example of a subdomain sharing a robots.txt file. However, on domains that are set up as their own subdomains they have different robots.txt.  Take a look at the many differences between subdomain1-1000.wordpress.com/robots.txt vs wordpress.com/robots.txt.  If you set up a subdomain that isn't just a reflection of your root domain, then you'll need to create a robots.txt file as well. Cheers!

            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!

            Robots txt. in page with 301 redirect

            We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? Thanks

            Blocked jquery in Robots.txt, Any SEO impact?

            I've heard that Google is now indexing links and stuff available in javascript and jquery. My webmastertools is showing that some links are blocked in robots.txt of jquery. Sorry I'm not a developer or designer. I want to know is there any impact of this on my SEO? and also how can I unblock it for the robots? Check this screenshot: http://i.imgur.com/3VDWikC.png

            Guys & Gals anyone know if urllist.txt is still used?

            I'm using a tool which generates urllist.txt and looking on the SEO Forums it seems that Yahoo used to use this. What I'd like to know is is it still used anywhere and should we have it on the site?

            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.

            Do knowledge base plugins on a subdomain have seo benefit?

            Hi SEO Moz, We want to use a knowledge base plugin (cheaper & faster than building it ourselves) where we can have Q&As for our website. We want this to help with our SEO by adding in our keyterms that we want to rank for. We've looked into TenderApp & Get Satisfaction which look like good solutions - however, as they're both on a sub-domain do we get any seo benefit from this? When people link to our knowledge base, will this help our website at all - or is the benefit going to go to TenderApp/Get Satisfaction? For instance - Our website URL is http://widget.products.com The KB URL is http://widgetsupport.products.com If the above plugin is not a good solution, is there anything else that is better? Any help will be greatly appreciated!! Thanks.

            Allow or Disallow First in Robots.txt

            If I want to override a Disallow directive in robots.txt with an Allow command, do I have the Allow command before or after the Disallow command? example: Allow: /models/ford///page* Disallow: /models////page

            How to move my blog from subdomain to subfolder?

            Not an unusual situation, I have a blog on blog.domain.com it has quite a few blog postings.  The platform is old and will be scrapped, but the blog content itself is going to be moved to domain.com/blog. The current process is we are manually listing all linked to/content pages and we are going to 301 redirect them to their counterparts on the new blog.  This is going to be a tedious process. A) Is there any way to automate the moving of the blog? B) What is the best way to do the massive 301 redirect, php headers, .htaccess?  Should we move the individual pages with redirects, or redirect the domain in the .htaccess (this will be very difficult to match all the titles and file structure)?
