I see a lot of threads and questions from publishers in the community saying that site EPMV is too low, or publishers expect to be earning more revenue from ads. While there are a variety of things that go into this (good ad setup with Ezoic, traffic quality, niche, main geos, browser type etc.), I often find that publishers would benefit greatly from diving into Big Data Analytics to understand what drives revenue and what actions to take based on their specific data rather than general theories.
I encourage all publishers to review this interactive article which will help provide valuable insights on what drives EPMV.
