If your site is eligible for a re-review there will be a reapply option showing in your monetization tab in your dashboard.
If there is not reapply option then it is likely your site is not approved due to one of these common reasons:
Adult / Sensitive Content
Download / Streaming Websites
As a Google certified publishing partner, Ezoic must uphold the same content policies even though your status with Ezoic is not tied to Google. Unfortunately we cannot provide specific information on why your site wasn’t approved for Ezoic’s platform.
For additional information, please see the Ezoic Platform Requirements and Google Content Policies.
