That assumes two things: 1. That such a tool couldn’t be limited to the big players (it could) and 2. That “small sites trying to run ads to get by,” aren’t part of the problem.

These sites are all pretty much designed (poorly) around their ads, which limits their usefulness. Have you tried looking up recipes online? A bread recipe with 5 ingredients is 30 pages long!!!
