It's clear that audience fatigue is a significant issue, but what's often overlooked is the role of creative fatigue in campaign performance. I've seen campaigns where frequency was high, yet performance remained stable for an extended period, simply because new creatives were being tested and rotated regularly. The moment creative testing stopped, the audience suddenly became fatigued, and performance dropped. Rotating creatives and building variations around a winning campaign has been a game-changer for me, and it's helped to mitigate the effects of audience fatigue. By doing so, I'm able to keep my campaigns fresh and prevent creative fatigue from setting in. This approach has performed noticeably better than trying to scale a single winning campaign aggressively.
