My product: [DESCRIBE IN 2-3 SENTENCES — what it does, who it is for, what problem it solves]. My 3 buyer personas: Persona 1: [JOB TITLE, main pain, what they care about most], Persona 2: [JOB TITLE, main pain, what they care about most], Persona 3: [JOB TITLE, main pain, what they care about most]. Write landing page copy for each persona: 1) Headline that speaks directly to their specific pain (not generic), 2) One-sentence subheadline on the value, 3) 3 feature bullets framed around their priorities, 4) CTA text under 5 words. Do not use generic SaaS language. Each variant should feel written specifically for that person.
