How to Identify Creative Fatigue
Creative fatigue shows up in your metrics as a combination of falling CTR, rising CPC and CPM, declining ROAS, and increasing frequency (the average number of times each person has seen your ad). When frequency exceeds 3-4x for prospecting campaigns or 8-10x for retargeting, fatigue is likely setting in. In Meta Ads Manager, monitor the 'Frequency' column alongside CTR and cost metrics. A sudden performance decline across an ad set that was previously working well is a classic fatigue signal.
