Hi pauseweb,
Thanks for reaching out.
I’m not sure if I understood you correctly. According to my understanding, you have 20 websites, and on these websites, the delivery of ads was limited.
Advanced Ads, unfortunately, does not have a magic button to identify the cause of this. However, we often hear about such cases, mostly due to invalid traffic or click fraud.
AdSense itself offers some information about this. Please log in to your AdSense account and navigate to the Policy Center. You may find reasons why you are affected by this action and why the limit has been set there.
Advanced Ads Pro provides an option to stop loading AdSense ads for specific users who have reached a definable click limit. This click fraud protection can help you avoid issues with your account.
I hope your limit will be lifted quickly, and the ads will come back. If not, here are some other networks you might want to test.
Best regards,
Joachim
