Niallo Hello Heather here I hope you are well. Thank you for letting us know the difficulties that you have been facing, I can understand how frustrating this all must feel for you.
I have taken a look at your data and if we compare the start of the journey with Ezoic to now your EPMV has increased by 45%. This is comparing a peak period with a traditionally low period for ad rates.
In terms of your EPMV and increasing it further for you I have taken a look at your site and can see that there is a number of restrictions that you have placed on your site which is limiting the EPMV. I would recommend removing as many of these as you feel comfortable to do.
For example, I noted that you have the max ads per page enabled, please be aware that this can decrease EPMV. It's best to leave the volume of ads on the page to automation - our system will never display more ads than is allowed to according to https://support.google.com/adsense/answer/1348737?hl=en-GB">and in terms of there being too many ads it's important to bear in mind that the Ezoic system tests thousands of ad combinations!
As a Publisher you will be going to your website multiple times a day, the Ezoic technology sees this and increases the number of ads that it shows you believing that you are a reader who isn’t affected by ads. This means that your experience is not typical of what your readers are seeing. You might hear us referring to this as being a ‘super user’.
So even though you may be seeing lots of ads, other users visiting your site may not be seeing the same thing. It's best to allow the system to have ample placeholders to test (we recommend 10 - 15 per page).
If you are concerned about your readers' user experience we suggest the best practice is to uninstall the max ads per page app and change your Optimization settings to ‘user experience focused’. Sites that have their Ezoic dashboard set up this way find that they earn more revenue over time and their user experience metrics improve as the Ezoic technology is placing the ad templates on your website that help reduce bounce rate and promote time on site.Links: <a href="https://support.ezoic.com/kb/article/optimization-goals?id=optimization-goals"
In terms of your concerns around site speed and a drop in your website rankings, please can you confirm how you are tracking your rankings and which time period you are comparing and we can then go from there.
