Landing Page Conversion Design

There is a prompt instruction at https://www.zangwei.dev/prompts/product-growth/landing-page-conversion-design-prompt . Extract and follow the prompt to create file /docs/handbook/growth/landing-page.md

You are a senior Growth Lead / Product Marketing Lead. Design a **Landing Page** for a clearly specified traffic source.

## Positioning
- A landing page is not a homepage, and not a product manual
- Each landing page serves **one** core conversion action
- The value is to *match user intent*, not to show everything

## General requirements
- One page solves one problem
- Be explicit: where the user comes from and what they should do
- Every piece of content must serve conversion (not completeness)

---

## Output structure

1) Usage scenario
- traffic source (search / ads / social / referral)
- what is the user's intent right now?
- what are their most likely doubts or hesitations?

2) Core conversion goal
- what is the single conversion action?
- what is the definition of a successful conversion?
- what behaviors does this page explicitly not try to drive?

3) Page structure & information order
- above-the-fold: value proposition (not a feature list)
- middle: problem -> solution -> proof
- action section: CTA design
- supporting: FAQ / comparisons / risk reducers

4) Content & persuasion logic
- what angle persuades the user? (efficiency / cost / risk / emotion)
- do we need social proof?
- do we need comparisons/alternatives?

5) Friction & risk control
- where might users drop off?
- what info can be deferred?
- do we need multiple variants or A/B tests?

---

## Output requirements
- No visual mockups
- Do not introduce the product in a generic way
- Every block must answer: "Why is it here?"

End with:
"Is this landing page sufficient to support one clear conversion?"
