Creative Frameworks
The Hook-Insight-Offer structure (Meta / TikTok)
- Hook (line 1): pattern interrupt, specific pain, or bold claim
- Insight (line 2): why this matters / the turn
- Offer (line 3): what to do next with a specific incentive
The Match-the-Intent structure (Google)
The ad must match the search query. If someone searches "crm for small business":
- Headline 1 includes "crm for small business"
- Headline 2 = differentiator
- Headline 3 = CTA or offer
- Description = proof + benefit
The B2B structure (LinkedIn)
- Intro: name the audience, name the outcome
- Headline: specific result
- Description: proof + CTA
Output Format (per platform)
## [Platform] Ad Set — [Product / Campaign]
**Audience:** [targeting notes]
**Offer:** [incentive]
**Landing page:** [url]
### Variant A — [Angle name]
- **Primary text / Intro:** "[copy]" (X/125 chars)
- **Headline:** "[copy]" (X/27 chars)
- **Description:** "[copy]" (X/27 chars)
- **Angle:** [what this variant is testing — pain, status, curiosity, social proof]
### Variant B — [Different angle]
...
### Variant C — [Different angle]
...
### Creative brief
- Visual: [describe — single image, carousel, UGC-style video, animated]
- Hook second: [first 3s of video or headline of static]
- CTA button: [Shop Now / Learn More / Sign Up / Download]
Always ship at least 3 variants per platform testing different angles. Ad platforms learn fastest when fed multiple creatives.
Testing Matrix
| Variable | Test |
|---|
| Audience | Broad vs lookalike vs interest vs retargeting |
| Angle | Pain vs outcome vs identity vs status |
| Hook type | Question vs claim vs story vs stat |
| Creative | Static vs video vs UGC vs animated |
| CTA button | Learn More vs Sign Up vs Get Offer |
Only test one variable at a time — changing creative and audience together gives you no learning.
Policy Checklist (review before shipping)
If a claim is even slightly borderline, flag it explicitly in the output rather than shipping it and risking account suspension.
Pre-flight
- Offer / product / price
- Target audience
- Platform(s)
- Landing page URL
- Any existing winning ads to preserve angles from
- Brand voice (load BRAND-VOICE.md if present)
Quality Bar
- Count the characters. Never ship copy over the limit.
- Never copy the organic social copy into ads — they're different mediums.
- Never promise what the landing page doesn't deliver. Mismatch tanks Quality Score on Google and Relevance Score on Meta.
- Each variant must test a distinct angle — "Variant B: same message, different emoji" is useless.
