This is going to sound really strange as I'm not very technically minded and I don't have all that much information to give. But I really need some help with this if someone is able to ...
I've been looking after a client's website, basically just doing a bit of SEO here and there, they are away at the moment so I don't have contact with them or their developers but something has gone wrong on their site. The other day my search query data from webmaster tools suddenly stopped working. No rankings have dropped and I'm still getting traffic data in analytics but nothing for impressions, or CTR in webmaster tools. It's completely flat-lined.
I resubmitted the site for verification in webmaster tools but this seemed to have no effect. Now, this is where my knowledge of things starts to fade - there are a lot of pages blocked by robots.txt (webmaster tools reports 10,000). The site is a movie streaming site so I can understand there are quite a few pages they want to block. I'm not sure if this is the problem as I was getting the webmaster tools data fine for months and nothing has changed in the robots.txt that I know of.
Another thing that might be an issue is that the entire site is https. I'm assuming that the http version redirects to the https because the https is the only one that is indexed. I'm confused though as all of the backlinks point to the http version. And I've just realised that they don't even have a sitemap! Also, the robots.txt is called [mysite.com...] The more I read about this stuff the more I realise how much of a mess this site is. The main thing I need though is for the search query data to start coming through again and I can deal with the rest later. It's really strange because everything was working fine before and now it has suddenly stopped and I don't think any changes have been made.
Does anyone have any suggestions about how I can get this working again? Any help would be much appreciated. And, remember - I'm not all that familiar with coding!
