Blog posts automatically getting excluded from GSC

I don’t know why but for some reason every day some of my posts are getting excluded from Google search. Any reason why?

FYI, I’m using DGO as host and Ezoic as Display Ads.

Such case happens when page content is very thin or almost duplicate.

But what if they were ranking for like last 3-4 months and suddenly this happens? I’m 100% sure it’s not duplicate content and 1200+ words don’t sound thin content right? :wink:
