Everyone talks about testing hooks, rewriting copy, or tweaking the first 3 seconds when CTR drops and CPMs spike. But audio fatigue has been a massive overlooked lever for me.
On a couple of e-comm/DTC accounts, we had winning creatives hit a wall last month. Instead of scrapping them or ordering new shoots, we ran an isolated test:
- Kept the exact same footage and visual hooks
- Completely swapped the background music
We ditched the robotic corporate loops and tested authentic indie tracks. The result? The same visuals saw a 15-20% CTR bump, and CPAs dropped back into profitable territory. It felt like the audio swap shifted the pacing and served the ad to a fresh pocket of the audience that had tuned out the old version.
Are you treating audio as a systematic variable in creative testing, or is it just an afterthought during editing? Curious how others manage sound design at scale.
