Ad Creative Monitor — Catch Fatigue Early

Creative fatigue is the silent killer of ad accounts. CTR drops 0.1% per day, frequency ticks up, CPC quietly inflates — and by the time you notice in Ads Manager, you've burned through budget.

This skill watches for those signals daily and flags creatives that need rotation.
