Exactly, this is the point.
When you have little traffic and make little, with Ezoic (if approved) you have to understand that you will make even less as you'll share earnings with another company.
While many users think of this as an easy way to get in with ad networks, without increasing traffic this is a way to even lower earnings.
Ezoic is for those who have steady traffic and revenue but wants to squeeze more, without diving into ad operations which is a very difficult process.
Working in Ad Ops field I can tell that hiring Ad Ops expert would still be better as you would have a personal expert working on your site vs Ezoic working with dozens of sites without special attention for yours.
