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.
Hereâs the problem: Youâre 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, youâll know whatâs working and whatâs just wasting spend.
