What problem does it solve?
You have a value prop and ad budget but no structured angles, hooks, or platform-safe copy variations to run meaningful tests.
Who is it for?
Indie SaaS marketers running $1k–$10k/month experiments who already know audience and offer but need creative velocity.
Skip if: Organic SEO long-form, brand manifestos without CTAs, or campaigns with zero positioning input—feed it audience, offer, and channel first.
When should I use this skill?
User requests Meta, Facebook, Instagram, or Google ad creative with audience, offer, budget, or keyword context.
What do I get? / Deliverables
You get multiple angle-labeled ad sets with compliant character counts, visual notes, and a recommended test order before spending.
- Angle-labeled ad variant sets with hooks and CTAs
- Platform-compliant headline and body copy
- Visual direction notes and recommended test order

Journey fit
Paid acquisition copy belongs when you are pushing the product into channels—not while you are still scoping core features. Distribution is the canonical shelf because output is campaign creative for Meta, Google, and similar performance channels.
How it compares
Use instead of one-shot chat ad paragraphs that ignore Meta 125/40/30 limits and skip systematic angle testing.
