chouqfih Hi,
When looking at EPMV There are a number of things to look at to help troubleshoot.
1- You will want to think of any changes that happened around the time you noticed a change in EPMV.
New plugins?
Updates?
Theme Change?
All these may have an affect on your EPMV. Theme Change for example will cause the a new layout for the system to learn from so it would need to collect new data. Placeholders could remove or no longer show as the div they where in is no longer there, causing Earnings to drop.
This is usually one of the main reasons sites see EPMV changes. https://support.ezoic.com/kb/article/why-changing-your-theme-can-impact-revenue
If you update placeholders after a theme change it can take time to build the site revenue back up to what it was. https://support.ezoic.com/kb/article/do-i-need-to-do-anything-if-ive-already-changed-my-sites-wordpress-theme
2- Is the change that you are seeing to your EPMV happening just for you or globally?
Check out to see if your Earnings/EPMV follow the global trend: https://adrevenueindex.ezoic.com/
You can filter based on different locations for your traffic.
3- Have any changes been made to Ezoic in that time before that could have caused the drop?
Removing types of ads?
Putting Ad restrictions up?
Ads.txt changes?
4- Have you made changes to Marketing or SEO?
There are many factors that can affect Earnings. Looking at these can help identify what could be the cause. This is a helpful article covering these points: https://support.ezoic.com/kb/article/troubleshooting-epmv-changes
Your Account Manager Can go more in depth with you.
Its also worth noticing Ad rates are lower than previous years due to the climate at the moment, so this is another factor to keep in mind.
