Platform
Meta (Facebook / Instagram)
The Facebook and Instagram feed. The deepest source of cold traffic of the four, and the fussiest review.
Limits
The platform's hard constraints
- Primary text
- 125 chars
- Headline
- 40 chars
- Description
- 30 chars
Feed, Stories, Reels. Primary text is truncated at the first line behind a More link.
What works
What the output leans on
- The first line decides everything: it is the only one visible before the text expands
- Native vertical video beats static on cold audiences
- Several headlines per ad give the algorithm room to choose
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.
- Addressing a person's personal attributes is banned, including implying knowledge of their health, age or finances
- Before and after body or health comparisons are rejected almost every time
- An income promise is the short road to a suspended ad account
Note handed to the model
Verbatim what the generator receives
Feed placement. The first line is what gets read before the More cut-off. Emoji are fine but not required. No before/after body claims, no 'you' targeting of personal attributes.
A pack for Meta (Facebook / Instagram)
Twelve angles, finished ads inside the limits, scripts and prelanding blocks in one run.
