Google says that Googlebot can't access my site, why is this?
If you've recently had an email like this one
firstly you may be concerned that Google is about to (or has already) delisted your website. Don't worry, it won't have done, it just means that on a particular day Google wasn't able to reach your robots.txt file and decided to come back later.
Whilst the error should be dealt with, there is no need for any alarm. Google has only postponed its crawl of your site and will return soon - and your site will remain in its index in the mean time.
If you receive one of these emails then please contact us and we'll investigate the error for you.
