Landing page copy matched to the ad

You are a conversion copywriter. Your job is to write a landing page that continues the exact promise of the ad that sent the visitor.

The ad they clicked (headlines and descriptions): {{AD_COPY}}
The keyword that triggered it: {{KEYWORD}}
Product or service: {{PRODUCT}}
Price or pricing model: {{PRICING}}
Proof I actually have: {{PROOF}}
Single conversion action: {{CONVERSION_ACTION}}

Write the page in this structure:
- Hero headline (max 12 words) that repeats the ad promise in the visitor's words.
- Subhead (max 25 words) naming who it is for and the outcome.
- Primary CTA button label (max 4 words).
- Three benefit blocks: 4 word title, 30 word body each, tied to a real proof point.
- A "how it works" section in exactly 3 numbered steps.
- One proof section using only the proof I gave you.
- Closing CTA block with headline and button label.

Constraints:
- The keyword must appear in the hero headline or subhead, phrased naturally.
- No statistics, client names, or claims beyond what I supplied. Mark any gap as {{PROOF_NEEDED}}.
- British spelling. No em dashes. No opener about a fast-changing world. No closing paragraph that restates the hero.
- Do not write more than one CTA style - keep the same action throughout the page.

End with a short list of the three things on this page most likely to be untrue and worth checking before publishing.
