Analyse Meta Ads frequency (impressions per unique reach) and correlate with conversion rate to recommend frequency caps per campaign objective. Identifies the inflection point where additional impressions stop driving conversions and start burning budget on overexposure. Meta-specific — complements meta-ads-deep-audit's creative fatigue findings with a concrete cap number. Activate when the user says "frequency cap", "audience saturation", "frequency too high", "overserving ads", "frequency recommendations", or asks how often the same person should see an ad.
