Interesting example, @cyrusshepard. The others mentioned in the <#C05VC65A8D8|> channel are de-indexed and seem like a manual penalty that will take them to zero without intervention.
This site is clearly losing their top listings. I checked a good 30+ both for featured snippets/page two listings and they are no where to be found. It seems like the kinds of pages that would be described as AI.
However, they seem ok for brand and other reasonable terms (e.g., "actionable reporting" - #2) still ranking quite well.
Also, somewhat interesting is the Help subdomain (albeit incredibly small) is up slightly during the same two day period on ahrefs.
Based on this single site and a cursory glance compared to the other sites called out on socials that have been de-indexed, there is a nuance between punishing a site and suppressing "unhelpful" content.
Curious to see more results like this to better understand the distinction -- purely as an SEO detective (not because I'm guilty of anything).
