Brothers, I often hear coaches say that you have to spend a little on ads to see if they are any good. Now my next question is: Suppose you do a CBO test with 10 ads and you see that most of the spend goes to 1 ad and it has reached the $100 spend, BUT not your ROAS KPIs. In that case, you can actually turn off that test CBO right away without having to test the other 9 ads, right? Because Facebook itself knows which ads will perform best, so if the first ad that gets the most spend doesn't even reach the ROAS KPIs, why would the other ads?
