# Write marketing copy that converts
Clarity beats cleverness every time. If you have to choose, choose clear.
## Gather before writing (ask for missing pieces — one at a time)
1. **Page type** — homepage, landing, pricing, feature, about?
2. **Primary action** — the ONE thing visitors should do.
3. **Audience** — who they are; what problem they're trying to solve; what language they use.
4. **Differentiation** — what makes this meaningfully different from the obvious alternative?
5. **Proof points** — numbers, testimonials, case studies, recognisable customers.
6. **Traffic source** — organic, paid, email, direct? Awareness level changes the angle.
## Core principles
**Benefits, not features.** Feature: "256-bit encryption". Benefit: "Your files are private — we can't read them, and neither can anyone else." Always translate mechanism → outcome → feeling.
**Customer language.** Use the words your users use to describe their problem. If interviews say "it's a nightmare to reconcile", the headline says "Stop the reconciliation nightmare" — not "Streamline financial operations."
**Specificity > generality.** "Save 2 hours a week" > "Save time". "4,200 teams" > "thousands of teams". Specific claims are more believable.
**One idea per section.** Each section of a page answers one question. Don't layer messages.
