Mediation Still Pending?
The approval process for AdSense can take some time. If you have signed up and joined our AdSense Certified Partner Program, do not worry if the app is still pending. If you have not already applied for the program, contact your Ezoic representative. AdSense Mediation will remain pending until one of our Ezoic representatives sends you an individual AdSense invite link.
So, if you haven't received one of these yet, please reach out to your Ezoic representative, and they'll be able to provide you with one!
Even then, AdSense can remain pending until your AdSense account competes with and wins against the Ezoic Ad Exchange.
