Unfortunately, Ezoic isn’t always at liberty to discuss review processes as there are elements of our approval process which are proprietary.
What we can say is sites have to have great quality traffic and highly engaging original content. As we are Google Certified Publishing partners sites we work with must also follow all Google content, behavioural and traffic quality policies - you can find more about those here.

We’re very grateful for your understanding in this matter, and sincerely wish you the best in your future endeavours.
