Fatigue Detector

Doctrine

"CTR down, CPM up, must be fatigue" is the most common misdiagnosis in ads. Sometimes it is the auction, the season, or a broken pixel. The two-condition rule cuts false alarms: an ad is fatigued only when frequency > 4.0 AND CTR is down 30%+ from its own baseline. Post-Andromeda, ad lifespans compressed and fatigue scales with spend more than with days, so small budgets fatigue slower than the "20 new ads a month" crowd claims. The owner's version of this pain: "the exact same ads that cost $6.85 a lead now cost $30.90."

When to use

• A previously-working ad got expensive.
• Before killing anything: impatience kills more winners than fatigue does.
• Needs a Meta Ads MCP, read access.
