<objective> Write marketing strings for landing pages, SEO meta tags, social cards, and paid ads. Output: structured copy ready to drop into design / CMS / ad platform.
Use when the user wants marketing-facing prose: a hero section, feature blurbs, pricing-page descriptions, SEO meta titles/descriptions, Open Graph card text, Google/Facebook/LinkedIn/X ad copy, FAQs for a marketing site. Not for product UI strings — that's `microcopy`. Not for release notes — that's `release-notes`. Not for viral social posts — that's `viral-text`.
This skill does NOT:
</objective>
Read the brief (product, audience, value prop) → identify what surface needs copy (hero / feature / SEO meta / ad) → apply the right formula → respect platform char limits → strip marketing hype → return paste-ready copy.
1. **Get the inputs.** Product name + one-line description, target audience, primary value prop, top 1-3 differentiators, competing products (for positioning). If user didn't provide, ask the bare minimum and pick sensible defaults for the rest.
2. **Identify the surface.** See `references/surfaces.md`:
3. **Apply the formula for the surface.** See `references/hero-formula.md` for hero; `references/feature-blocks.md` for features; `references/seo-meta.md` for SEO/OG/Twitter; `references/ad-copy.md` for paid ads.
4. **Respect char limits.** Each platform truncates differently — see `references/char-limits.md`.
5. **Apply universal rules.** Plain language, specific value, no marketing hype, action-oriented CTAs. See `references/banned-patterns.md` for what to strip.
6. **Run `writer` final pass.** Marketing copy passes through writer for anti-neuroslop + typography cleanup. Marketing context allows ONE intensifier per copy block (vs zero in dev docs), but everything else still applies.
**Delete the water, not the function.** The CTA, the offer, the price, the deadline, the link and the contact are the working parts of a landing page — writer's default treatment is deletion, and here that would strip exactly what makes the page earn. Treat them by replacement or simplification instead. A cleaner hero with no offer has stopped doing its job. After the pass, verify every functional element of the draft survived, at least one instance of each. See `forbidden-substitutions.md` in the `writer` skill.
7. **Output.** One or multiple strings depending on surface. For ads — usually multiple variants (3-5) for A/B testing.
