Hi @Raheel - hope you're keeping well!
Looks like the new site that was just approved, ad*********k.com, only has three placeholders on the entire site.
We'd highly suggest adding more placeholders to increase competition for ad space on your site and allow the Ad Tester system to work properly and test locations on your site.
However, the reason why the site isn't currently showing ads is because the site's using an incompatible caching element on the site. We can see that Ezoic versions aren't able to show to visitors, due to 'edge' caching being enabled.
Any edge/page-level/browser/HTML caching needs to be disabled, they will stop Ezoic from being able to optimize the site properly.
