An ad creative looked like a winner for three days, then collapsed after frequency and audience overlap rose.
Direct answer
The creative was not scaled further because the early win came from a narrow warm audience and did not hold under broader delivery.

- Checked contribution margin after the initial spike.
Result and lesson
The team avoided scaling into a fatigue curve and built a better creative testing rhythm.
FAQ
How long should a creative test run?
Long enough to see delivery beyond the easiest audience and enough conversions for a decision, not just one strong day.
What signals indicate creative fatigue?
Rising frequency, falling CTR, weaker new-customer share, CPA increase, and comments showing repeated exposure.
Should a false winner be deleted?
Not always. Keep the learning, extract the angle, and test variants with cleaner audience and budget controls.
