How much does a animal niche website with 4M monthly visits make?

Paw My Gosh gets about 4M visits a month according to SimilarWeb. CPM would probably be around $1-2. So do they only make $4000 to $8000 a month? Am I missing something? Would think they make way more.

Then a site like ViralNova gets 8M according to SimilarWeb = around $8000 a month with $1 CPM. How does that make sense? They sold for $100M

I must be missing something.

these websites estimations are bullshit what comes to real stats/value so I wouldn't make predictions based on that.

Traffic estimations using free tools are never very accurate, especially when it comes to value. Only way to accurately know what they earn is to talk to the owner.
