CBO Plays Favorites!
Posted by on February 15, 2021 at 8:14 pmCBO Campaign with 2 Ad Sets
Ad Set One = 1% lookalike
Ad Set Two = 2% lookalike
The CBO constantly picks the 2% as the better performer and funnels the budget into this ad set…
Problem is, both audiences perform almost identical, with CPA varying only $0.50 cents between them.
So my “worse-performing” ad set always hits learning limited (28 events max)
​
Without raising the budget, what can I do here to keep my 1% out of learning limited?

Min and max spends at the ad set level.
Edit: I’ll also add, who cares ? If your 2% performs almost identically do your 1% then your test is over – just run the 2% LAL, it’s more scalable. Then test a 3 or 5% against that.
