I have received the following message from MOZ on a few of our websites now Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster. I have spoken with our webmaster and they have advised the below: The Robots.txt file is definitely there on all pages and Google is able to crawl for these files. Moz however is having some difficulty with finding the files when there is a particular redirect in place. For example, the page currently redirects from threecounties.co.uk/ to https://www.threecounties.co.uk/ and when this happens, the Moz crawler cannot find the robots.txt on the first URL and this generates the reports you have been receiving. From what I understand, this is a flaw with the Moz software and not something that we could fix form our end. _Going forward, something we could do is remove these rewrite rules to www., but these are useful redirects and removing them would likely have SEO implications. _ Has anyone else had this issue and is there anything we can do to rectify, or should we leave as is?

When I crawl my site as a root domain, I get more errors is my campaign than when I set my site as a sub domain. Which one is the correct way: root domain or subdomain. My site is www.aa-rental.com
