Very difficult. It is not just technical but there are business reasons too. That said, it is possible to make drastic adjustments that help monetization, UX, and still have ads. I did that as a short-lived experiment for a very ad heavy mobile site (SFGate): Main points are here (not a ton of details) in this sanitized post-redaction deck: https://docs.google.com/presentation/d/12ds0b4nTxzcDy23te0Zmc9UOdx8HWsTf1UECwhxkNdo/edit https://docs.google.com/presentation/d/12ds0b4nTxzcDy23te0Zm... I had an extra labeling for non-ad sites so there was some distinction and would like to restore that. However look at El Diario - ads and number 1 spot! DotDash has numerous high performant sites (ThoughtCo etc) that have ads too.
