No, 0 link, we always wait at least 6 months before building links. So it's 100% clean as far as links are concerned.
As far as articles quality is concerned, to be honest, out of my 40+ websites, this is certainly the one with the best possible content. Super informative, writen for the visitor with a huge KW research...
So confusing on why it dropped ...
What we notice :
- Less and less mobile friendly pages on GSC (whereas normal indexing is fine and 0 error).
- When I run checks of rendering on mobile from
https://search.google.com/test/mobile-friendly?id=IsNZ8bbGS0sZ5vC8t2VApg page des not look fine at all
- When I check site:monsite.com on google, it only shows a few pages (11 on 57)
....let's wait and see...
