Hi prezla, thanks for reaching out.
Do I understand correctly that you are using different ad networks and/or other monetization strategies and would like to find out which one works best?
On the first glance, I see a few potential issues you might want to address.
First of all, you should be careful with sticky ad positions. AdSense doesn’t allow them unless you have their explicit consent.
I know you rather want to increase your revenue, but on that top position, ads are covering too much space, which normally doesn‘t result in more clicks and might give your site a bad rating when it comes to Chrome’s ad filtering.
It also looks like your mobile site is actually loading desktop ads, but not delivering them, which could also result in a penalty by AdSense or another ad network. You can use the “device” condition in Advanced Ads to remove these ads on mobile.
I am not sure if there is more potential for your site using ad networks anymore. Did you ever consider selling ads directly?
Let me know if you have a question regarding my remarks.
Thomas
