Claude for Landing Pages: Briefs, Copy Variants, and Page QA

This guide covers making landing pages with Claude, not Claude's own homepage. Claude handles three jobs here: a one-page brief (offer, audience, proof, main objection, one CTA), section copy plus 2–3 variants per element with one hypothesis each, and a pre-launch QA pass. You bring the offer, the proof, and the test tool. Claude can't run your test or pick the winner. Hub → Claude for growth. Voice → Claude for copywriting.

When to use Claude for landing pages / when not

Use Claude when you have a real offer and a named conversion goal. Good fits:

• a new offer or product page that needs a structured brief before anyone writes copy
• a hero/CTA refresh on an existing page
• a small variant set for a test you've already planned in your own A/B tool
• a QA pass the day before launch: claims, message match, CTA count, placeholder links

Don't use Claude when:

• there's no real offer, proof, or audience yet (Claude will fill gaps with plausible fiction)
• the page makes regulated claims (health, finance, legal) and you skip human or legal review
• you expect it to pick the winning variant or predict a conversion rate
• the real job is building and deploying the page. That's a different guide: Claude Code for your first website.

Landing page jobs map — brief, variants, QA

Bridge: message match connects this page to the ads guide (creative) and the copywriting guide (voice). If the ad promises "set up in 5 minutes" and the hero says "enterprise-grade onboarding," fix that before any variant test.

Workflow — ship one landing page in 8 steps

1. One goal, one CTA. Write the conversion action in one line (book a demo, start trial). Can't? Stop here.

2. Page brief. Offer, audience, the proof you hold (customer quotes with permission, real numbers, logos you're allowed to show), the main objection, and a must-not list. Missing proof → [GAP], never a filler.

3. Section skeleton. Hero → problem → solution → proof → objections → CTA. Cut sections the brief can't support.

4. Draft inside the brief. Claude writes each section from brief facts only, plus your voice notes.

5. Variants with hypotheses. 2–3 per hero headline and CTA. Each one states what it changes, why it might work, and what result would prove it wrong.

6. Message-match check. Compare the page against the ad or email that sends traffic. Fix the promise before testing wording.

7. Page QA. Claims needing proof, CTA count, jargon, placeholder or broken links, scannability of copy on a narrow screen, alt-text gaps you can see in the copy.

8. Human ship + test in your own tool. Output stays a draft until someone signs off. Your A/B tool runs the test.

Prompts (≥3 copy-paste)

Full cards live in our local prompt pack. For broader marketing prompt specs, see Claude prompts for marketing.

1. Page brief builder

You are a landing page brief builder. Build ONE page brief from PROVIDED inputs only.
REQUIRED: Offer; Audience; Conversion goal (one action); Proof I hold (or "[GAP]"); Main objection; Must-not list (or "none"); Traffic source (or "[GAP]").
STEPS: Restate the goal in one line → emit brief: offer · audience · promise · proof · objection + answer · single CTA · must-not → list every missing field as [GAP] and ask me for it.
RULES: Never invent testimonials, logos, customer counts, stats, or conversion numbers. One CTA only. Do not write page copy yet.
OUTPUT: brief | [GAP] questions | next action.

2. Hero + CTA variants, one hypothesis each

You are a landing page variant writer. From the APPROVED brief and current hero/CTA, write 3 variants for the hero headline and 2 for the CTA.
For EACH variant give: the copy · the single thing it changes (angle, specificity, objection, audience word) · hypothesis ("If we..., then... because...") · falsifier (what result in my test tool would show it's wrong).
RULES: Use only facts in the brief. No invented proof or urgency. No predicted conversion rates or "this will win." Keep the promise consistent with the traffic source.
OUTPUT: variant table | open questions | which variant to test first and why (reasoning only, no forecast).

3. Pre-launch page QA

You are a landing page QA reviewer. Review the PROVIDED page copy against the brief, proof list, link list, and traffic-source copy.
CHECK: (1) every claim → matching proof item or flag [NEEDS PROOF]; (2) message match: ad/email promise vs hero, offer, CTA; (3) CTA count and consistency; (4) jargon or undefined terms; (5) placeholder text, TODOs, lorem, or links marked # / example.com; (6) scannability: paragraphs over 3 lines, headings that don't say anything; (7) image references with no alt text in the copy.
RULES: Don't rewrite the whole page. Patch only failing lines, labeled DRAFT. Don't invent proof to make a claim pass. Don't estimate conversion impact.
OUTPUT: pass/fail checklist | patches | blockers before ship | "Do not ship without human review."

Agent block — landing-page operator

Paste into a Project's custom instructions, a Claude Code agent, or a system prompt:

You are the landing-page operator for this Project.

MATCH each request to one job: page-brief | section-copy | variants | message-match | page-QA.
REQUIRE offer, audience, single conversion goal, proof list, main objection. Missing → [GAP]; ask, don't fill.
WRITE copy only inside an approved brief. One CTA per page.
EVERY variant states one change, one hypothesis, one falsifier.
NEVER invent testimonials, customer logos, stats, ratings, or conversion numbers.
NEVER predict which variant wins or estimate lift. The user's test tool decides.
FLAG claims you can't trace to the proof list as [NEEDS PROOF].
ROUTE voice/tone work → /guides/claude-for-copywriting. Ad creative → /guides/claude-for-ads. Building/deploying the page → out of scope.
END every deliverable with: "Draft. Do not ship without human review."

Skills path — landing-page-qa stub

There's no official Anthropic skill for landing page QA as of 2026-10-05, so there's no install id to give you. Once you run the QA prompt every week, package it as a thin personal skill. Our outline (kept local, not published) covers inputs, the seven-point checklist above, and a fixed pass/fail output. It's a starting structure, not a tested package.

Stack glance

• Chat: one-off briefs, a quick variant set, a QA pass on pasted copy.
• Projects: put the offer doc, proof list, voice card, and past page briefs in knowledge so every request starts from the same facts. This is where the agent block lives.
• Claude Code: only if you're also building the page in a repo (first website guide).
• Skills: the landing-page-qa stub above, once the checklist stops changing.

Pitfalls + quality bar

• Variants without hypotheses. Five headlines with no stated reason teach you nothing, even if one "wins." Claude generates fast; you constrain.
• Too many CTAs. Book a demo, start trial, download PDF, and newsletter on one page = no clear goal.
• Invented proof. "Trusted by 10,000 teams" that nobody can source. Flag it, delete it.
• Ad/page mismatch. Testing wording on a page whose promise doesn't match the ad.
• Treating Claude output as results. A hypothesis isn't data. Only your test tool produces results.
• Skipping legal review on regulated or comparative claims.

Quality bar before ship: a brief existed before copy · one CTA · every claim maps to a proof item you hold · every variant has a hypothesis and a falsifier · message match checked · human sign-off.

FAQ

Can Claude write a landing page?

Yes, the copy and structure, inside a brief you supply. You own the proof, the offer details, and the final call.

Can Claude A/B test my landing page?

No. It drafts variants and hypotheses. Your testing tool runs the experiment and measures it.

How is this different from the copywriting guide?

This page treats the landing page as one unit: brief, section copy, variants, page QA. Claude for copywriting covers voice and copy drafts in general.

Should I use Claude Code for landing pages?

Only if you're also building the page. For the code side, start with Claude Code for your first website.

Can Claude predict which variant will convert best?

No. It can say why a variant might work and what would prove it wrong. It has no access to your traffic or conversion data.
