What it does

Write conversion-focused marketing copy for surfaces and audiences

Best for

Product marketer writing copy for sales funnel — produces outcome-focused copy that avoids adjectives, uses user language, and structures sections for conversion psychology (problem → solution → proof → CTA).

Inputs
  • · Surface (homepage, feature page, email, ad, onboarding, pricing)
  • · Audience type (new visitor, returning visitor, existing user)
  • · Conversion goal (sign up, upgrade, click through, understand feature, action)
  • · Positioning (target user, category, differentiator)
  • · Tone (formal, casual, technical, friendly)
Outputs
  • · Hero section copy (headline, subheadline, CTA, social proof)
  • · Problem section copy (pain points in user language)
  • · Solution section copy (2-4 capability blocks)
  • · Social proof section (testimonials, case study numbers, logos)
  • · Final CTA section
  • · Supporting copy (pricing, email subject, empty state, tooltip)
Requires
  • · Landing page pattern database (optional — via uiux tool)
  • · Brand voice guidelines (optional)
Preconditions
  • · Product positioning and messaging defined
  • · Target audience and intent clear
  • · Surface and goal specified
Failure modes
  • · Headline templates are generic ("specific > vague" rule is guidance, not guarantee)
  • · Doesn't A/B test copy variations — outputs single version per surface
  • · Social proof section is template format — requires real customer data to fill
  • · Doesn't account for regulatory/compliance copy (privacy, disclaimers)
Trust signals
  • · Step-by-step workflow (context → hero → problem → solution → proof → CTA → supporting)
  • · Headline rules (specific > vague, outcome > feature, user language, no common adjectives)
  • · Proof hierarchy (testimonials > case study numbers > logos > review aggregates)
  • · Section-level psychology (problem section uses 'you' language and specifics)
