Thanks for the information. I used automatic placeholder detection via the Ezoic chrome extension. So, I guess it detected only 4 best places to display ads. How can I add more placeholders to complete the monetization process? I tried using WP plugin too. But it's not working. For many days, it's displaying the option "placeholders are still being generated." So, can you guys help how can I easily get this sorted?
I'm trying to avoid the manual setup...looking for something more automatic via extension or plugin.
