Platform
TikTok
Vertical video with sound on by default. Advertising that looks like advertising does not work here at all.
Limits
The platform's hard constraints
- Primary text
- 100 chars
- Headline
- 40 chars
- Description
- 40 chars
In feed, full screen vertical video. The ad text competes with the video itself.
What works
What the output leans on
- A spoken tone and a first person camera rather than a studio look
- The first three seconds with no logo and no intro
- Short text: it is a caption for the video, not the ad itself
Review
What the policy pass catches
These rules are given to the model in the prompt, and the policy pass goes over the finished copy in a separate call.
- Banner aesthetics are recognised instantly and destroy watch time
- Unlicensed music takes the video down regardless of the copy
- The audience skews younger: promises and pressure work worse than demonstration
Note handed to the model
Verbatim what the generator receives
Sound-on, native-first. The ad text competes with the video, so it should be short and spoken-sounding. Avoid anything that reads like a banner.
A pack for TikTok
Twelve angles, finished ads inside the limits, scripts and prelanding blocks in one run.
