All of a sudden (I think it has to do with the update of a WordPress plugin, but I am not sure) I found several crawl errors when checking the site health in Google Webmaster Tools.
Specifically, these are
Googlebot couldn't access the contents of this URL because the server had an internal error when trying to process the request.
At the same time, I observed that my keyword rankings have deteriorated drastically.
Since I didn’t change anything on my website, can it be due to these crawl errors?
I am desperate and would appreciate any help.
I have two websites with the main website in the root directory of my space and the WordPress blog in the WordPress directory.
The crawl errors relate to the main website (root directory).
No idea... Please help!
