bazulinigor Have you made any changes to the site e.g. changed theme since the decrease in EPMV? As I mentioned, changes to EPMV are expected on a daily basis.
Additionally, adding placeholders isn't about increasing the total number of ads, as our AI will leverage that, but more about improving the AI testing so the ads that do show return more revenue. I suggested adding more mid-content ads/placeholders as if you view the site in mobile, there certainly could be more ads as the sidebar/siderail ads won't show to those users. Mobile traffic also tends to make less revenue too, so its important that Ezoic can test effectively on your site
