Today morning i got the email from Google web master account,it said Googlebot can't access your site.How to clear this error?
You should check source code of your website first, it'd be a chance to have noindex and nofollow tag into your robots and googlebot meta tags.
Thanks for sharing your views AB
Check if you block any page with your robot txt file or onsite robots code.
There also one more possibility if your website down then bots don't crawl you website for this contact your hosting support.
