Is publishing more content actually hurting your SEO?

Spent time auditing sites lately and kept finding the same uncomfortable pattern.

Turns out flooding a site with content before owning any topic is basically telling Google you're an expert in nothing specifically. The sites compounding fastest right now aren't publishing the most — they're publishing the least while covering their core topic more completely than anyone else. Depth beats volume every time and most people are still running the opposite play.

Anyone else finding that cutting content actually moved the needle more than adding it?
