I am new to Facebook Ads. I have run some push ads campaigns in the past and it is easy to optimize them using tracking tools because you know which Zone ID is giving you conversions.
My Question is how to go about optimizing Facebook Ads CPA campaigns. You cant put conversion pixel on Offer's thank you page as you don't have any control over them.
So visitor clicks on the ad and goes to landing page -> From their visitor goes to CPA campaign. So in this scenario how do I know what audience is performing well and what audience is giving me conversions?
