nickCC Ah that's great news that you have a meeting in place.
I have taken a look at your account and some of the things that I have noticed are:
1) that the pages that I have checked have a poor ad placeholder set up with ad placeholders missing or multiple ad placeholders of the same name on them.
2) the ad revenue index is lower in March than it was in February this will be impacting all sites globally you can see the ad revenue index here https://adrevenueindex.ezoic.com/ and this blog post walks you though what is happening with ad rates industry wide over the last 6 months https://www.ezoic.com/why-ad-rates-are-so-low-in-q4-2022-and-q1-2023/
3) I noticed that you aren't currently using Flickify videos on your site, these can help with your revenue, your standing with Google and your sites user experience metrics https://pubdash.ezoic.com/flickify/terms-of-use
4) In terms of what is happening with the Premium upgrades that you are seeing here https://premium.ezoic.com/premium/premium-messages these upgrades are based on your overall Ezoic revenue (this doesn't include Premium or Mediation) with the increase in traffic to your site this is increasing your revenue and so the Premium levels are increasing. The increasing Premium levels helps you to get more money back for your investment that you make.
