NHG Hello Heather here I hope you are well. I have taken a look at your Ezoic dashboard and can see that there has been a number of things that has happened which is impacting your EPMV.
The first which is impacting all sites is the economy and wider concerns, this article explains more about this https://www.ezoic.com/why-ad-rates-are-so-low-in-q4-2022-and-q1-2023/
Looking at your sites traffic it has declined and alongside this an increase in returning visitors. This has led to a drop off in user experience metrics as your readers are returning to pages that they have read before and just updating themselves on the information that they need rather than reading the whole article that they may have done previously. This gives Ezoic less time to monetize this traffic and means that advertisers may have already placed the ad that they wished to in front of this reader previously.
There is a heavy number of restrictions on your site which is impacting the EPMV potential. As a first step to resolving this I would recommend working through the advice here in Urgent revenue issues https://pubdash.ezoic.com/ezoicads/adpositions/recommendations
If you have any questions as you work through them please do let me know, I'd be happy to help further.
