Attention over time
Predicted viewer attention for every second, normalized to this ad's own range — the same chart every PreTestAds report gets. How to read it
What the curve says it does well
- Attention builds to a mid-video peak at 20.1s — the classic shape of top performers in this set, which mostly earn their biggest moment after the setup.
Where it slips
- The open is quiet relative to what comes later (first-3s average 32/100). On a paid placement that's swipe risk before the good part arrives.
- Predicted attention crashes at 34.2s and stays low — the spot to study for what loses the room (a slow beat, a repeated shot, dead air).
- Attention is mostly gone by the CTA window (final-third average 26/100) — whatever the offer is, few predicted viewers are around to see it.

What the ad actually says — auto-transcribed. Useful for studying how the script maps to the attention curve above.
So many of you want to know what the rain cloud humidifier sounds like, so I will play it for you at the end. I just want to point out a few details. So there are three levels of intensity for the dripping water and you can make it, you know, fast, medium, or low. You also have the ability to dim the light, I think like three settings, and then you can also run the drips with the light completely turned off. So here it is running with the light turned off. It also has a feature where it will cycle through the different colors. So I'm going to stop talking and just let you listen to the raindrops while it cycles through.
