Most 'audience' problems are creative problems — your CPM proves which

When CPA spikes, buyers blame the audience and rebuild targeting. Wrong half the time. Two metrics tell you where the leak is.

Diagnostic split (90 underperforming ad sets):
— High CPM + low CTR → creative problem (61% of cases)
— Low CPM + low CVR → landing page / offer problem (24%)
— High CPM + healthy CTR → genuine audience saturation (15%)

Most rebuilds touched targeting when the creative was the actual fault.

Fix: before rebuilding the audience, read CPM and CTR together. Fix in this order: creative → landing page → targeting. Targeting is the last suspect, not the first.

Read: rebuilding the audience to fix a weak hook is renovating the kitchen because the doorbell's broken.
