Hi there,
Monica here from support, I hope you're well today.
Why do you believe your EPMV to be low? Are you comparing your site's EPMV to something else? I'm not seeing a change around the 20th July, but I can see that your EPMV has dropped since the start of July, in line with current global ad rates, which you can view at a glance using the Global Ad Revenue Index at https://adrevenueindex.ezoic.com/.
To boost your EPMV, I recommend enabling the Expanded article button in Ezoic ads - ad types. An "Expand Article" button helps users with slower browser speeds by reducing initial load time and improving ad viewability. It temporarily shortens the page, preventing scrolling further without clicking the button, creating a clutter-free user experience while encouraging ad interaction.
All the best,
Monica
