One of the most common mistakes we see in Meta ad accounts is....Audience stacking.
Audience Stacking=combining multiple audiences (like interests, lookalikes, and retargeting) in the same ad set.
Here’s the problem: You’re testing too many variables at once. When performance is good (or bad), you have no idea which audience is driving it.
✅ If you want clear data, test each audience in its own ad set.That way, you’ll know what’s working and what’s just wasting spend.
