<b>CPM jumped overnight? Diagnose before you panic-cut.</b>
CPM spiked 40%, I almost killed everything → ran the checklist instead:
— Audience too narrow → broaden
— Frequency climbing → refresh creative
— Seasonal auction heat (holiday) → wait it out
— Relevance score dropped → new angle
It was frequency. Fixed in 10 min. CPM is a symptom, not a verdict. Find the cause before you torch the campaign.
