MOZ rankings HUGE drop to 1

[Torilion]

Hello,

My website's MOZ rankings dropped dramatically to DA 1 PA 1 MOZ rank 0 Backlinks 0. A problem seems that my backlinks are no longer recognised, as there are of course many backlinks active and not the 0 mentioned. Also, I recently experienced a big drop in Google SERP, only for my homepage (main keyword), not for subpages (longtail).

I don't know what might be the cause for the SERP and MOZ drop. The only thing I can think of is that the past months I first changed from http://www.mydomain to http://my domain and later to https://mydomain However this was done properly and added in Google search console. Also Google SC does recognise my backlinks still (eventhough most are to the old redirected http://www.mydomain version). Can this be the cause, or do you have any suggestions what might be the cause, or what I can do to find out? Obviously I am interested in finding out the reason for the big SERP drop as this might have to do with the same cause for the big MOZ drop. Thanks!

Hello Nicholas,

Thanks for your input. I think the rel canonical is set right as wel as 301s for the https migration.

However, this does point me to something maybe related: A while ago a tool suggested 'harmful dynamic content' was present, i.e. myhomepage/?p='largenumber' and this 14 times. On all these 14 url versions  my homepage dispayed. After consulting my website system's helpdesk I added 301s for these URLs to blogs, as it should have been caused by draft blogs.

However, I think this was totally wrong as I later found out adding /?p=anynumber is possible within the URL. So, basically I added 301s from home to subpages (i.e. blogs) and the problem I now have is poor SERP results for homepage (not subpages and not the blogs) and a huge drop in MOZ scores for this homepage. So, I disabled these 301s a month or so ago. What do you think?

Thanks!!

Hard to answer as there could be multiple issues with your domain changes.

I would definitely make sure everything is 301ing properly to your current website version. Also, maybe throw a "rel canonical" tag on the homepage so Google knows it is the "Master Version", although this may only matter if you copy and pasted from one domain that was already indexed to a new one.

Lastly, it sounds like the Moz OSE tool may have just had a glitch or is maybe not recognizing the 301 redirect to your new domain. I would check try the Moz OSE tool again, and also check out https://moz.com/learn/seo/redirection.
