Common mistake

Opening the builder first and "figuring out copy later," which produces generic Sign up for updates pages with no magnet contract. Fix: do not touch layout until Step 1 gives you a single positioning line and a banned-phrases list. Treat the builder as assembly only starting in Step 4.

Before you start
  • Working title of the magnet and format (PDF / Notion / sheet / video)
  • One-sentence ideal reader
  • The single before→after transformation the asset delivers
  • Claude open in the browser
  • A fast one-page builder account (Carrd recommended; Typedream, Framer, or Webflow if you already use one)
  • One primary call to action chosen (download / get the link / book a short call)
1

Lock the magnet contract (no page copy yet)

Clarify what the magnet is, for whom, and what proof you can use—before any headlines or sections.

Exact action

Start a new chat in Claude. Paste this brief (replace the bracketed parts with your real details): --- MAGNET TITLE: [title] FORMAT: [PDF / Notion page / sheet / short video / other] IDEAL READER: [one sentence — who they are + situation] BEFORE → AFTER: [what they have now → what they will have after using your asset] WHAT THIS IS NOT: [topics or promises you will not make] TRAFFIC: [cold / warm / referral-heavy] PRIMARY CTA: [pick ONE: get the download link / get the template / book a 15-min fit call / other — name it] --- Then send this instruction verbatim: "Do NOT write hero headlines, subheads, or any section copy yet. Using only the brief above, output exactly these three items: (A) One positioning line, max 140 characters, that states what they get and for whom. (B) Five banned vague phrases I must not use anywhere on the landing page (examples to avoid: 'valuable insights', 'level up', 'unlock your potential', 'skyrocket', 'game-changer'). (C) Three proof substitutes I can use honestly without testimonials — e.g. methodology note, explicit scope of what's inside, or what kind of result is realistic. No invented metrics or client names." Keep this chat open — you will reuse it in the next two steps.

You can read the positioning line aloud and a stranger would know what they get and who it is for. The transcript still has zero hero copy, bullets, or FAQ text.
Claude wrote headlines, hero copy, or full sections. Start a fresh message: "Reply with (A) positioning line, (B) banned phrases, (C) proof substitutes only. No section copy."

Map the section stack and first-pass on-page copy

Turn the contract into one Markdown draft: full single-scroll structure with two headline variants and word budgets.

Exact action

In the SAME Claude chat as Step 1, send: "Using the positioning line, banned phrases, and proof substitutes from your last reply (reference them as 'the positioning line', 'the banned list', and 'the proof substitutes' — do not paste them back in full), draft a single-scroll landing page for this lead magnet. Structure — use ## Markdown headers for each section: 1. Hero — headline + subhead + primary button label. Two headline variants: (A) direct outcome, (B) specific curiosity. Each subhead must repeat the reader and the mechanism (the asset format). 2. What you'll get — 5–7 bullets. 3. Who it's for / who it's NOT for — two short lists. 4. How it works — exactly 3 numbered steps from opt-in to outcome. 5. Mini-FAQ — exactly 3 Q&As. 6. Final CTA — same primary CTA as the brief, plus recommended form fields (default: first name + email only). Add an HTML comment per section with a word budget, e.g. <!-- hero ~40 words -->. Obey the banned list. No fake testimonials, borrowed logos, or made-up statistics." Wait for the full Markdown draft before continuing.

Every section from hero through final CTA exists in one Markdown doc; CTA wording matches the single primary CTA you chose in Step 1.
It reads like a SaaS homepage (feature grids, multiple unrelated CTAs, "solutions" jargon). Re-prompt: "Single reader, one asset, one CTA — remove nav-style patterns and anything that isn't one vertical scroll."

Compress, de-hype, and emit paste-ready blocks

Rewrite for scan-friendly, honest copy and labeled blocks—ready for your builder—including meta title and description.

ClaudeFreeOpen Claude
Exact action

In the SAME Claude chat, send: "Rewrite the landing draft above into paste-ready blocks. Rules: - Paragraphs: max 2 sentences each. - Bullets: each starts with a verb or a number. - Remove hype adjectives and anything on the banned list from Step 1. - No fabricated metrics, awards, or client quotes. Output ONLY these labeled blocks (use the exact label on its own line before each block): HERO SUBHEAD BULLETS WHO_FOR WHO_NOT_FOR HOW_IT_WORKS FAQ CTA_BUTTON FORM_LABELS THANK_YOU META_TITLE META_DESCRIPTION THANK_YOU = 2 sentences after opt-in plus one honest next step (e.g. check email, whitelist sender). META_DESCRIPTION max 155 characters. In FORM_LABELS, recommend first name + email only unless my original brief required more fields." Copy the output to a scratch doc, Apple Notes, or Google Doc for Step 4.

Each labeled block is short enough to paste without heavy editing; reading it aloud sounds human, not launch-week hype.
Wall of text or repeated superlatives. Re-prompt: "Cut 30%; replace vague adjectives with specifics; keep the exact labels."
4

Assemble the page in the builder (mobile first)

Paste blocks into a one-page site, set meta fields, wire the form, and fix mobile before desktop.

CarrdFree tierOpen Carrd
Exact action

In Carrd, start a new single-page site (or a blank one-page layout). 1. Top-down, paste your labeled blocks: hero, bullets, who / not-for, how-it-works, FAQ, final CTA. 2. Add a Form element for capture. Wire submissions to the destination you already use (Carrd notifications, Mailchimp, Kit, etc.). Match field labels to FORM_LABELS. 3. Set page title to META_TITLE and meta description to META_DESCRIPTION. 4. Use one primary button style for the main CTA. 5. Open mobile preview FIRST. Fix headline line breaks and any horizontal scroll before polishing desktop spacing. 6. Set the post-submit / thank-you state to show your THANK_YOU copy (inline, modal, or redirect). If you already use Typedream, Framer, or Webflow instead of Carrd, do the same assembly there — still one scroll, one primary CTA.

One vertical scroll tells the whole story; the form is easy to find; mobile preview has no horizontal scroll; a successful submit shows your thank-you copy.
Form never tested or thank-you missing. Do not continue to Step 5 until a test submit completes and you see the success state.

Publish, test submit, and draft the first outreach email

Go live, verify with a real test opt-in, then generate a short honest launch email in Claude.

Carrd + ClaudeFreeOpen Carrd + Claude
Exact action

1) In Carrd: publish, copy the public URL, and open it in a private/incognito window while logged out. 2) Submit a test opt-in with a disposable label (e.g. you+magnettest@yourdomain) so you can confirm delivery or your ESP inbox. 3) In Claude (new message is fine), paste the live URL and one sentence stating whether traffic will be mostly cold or warm. Ask verbatim: "Write 3 email subject lines and one email body (max 90 words) announcing this lead magnet to my list. Honest tone — no fake waitlists, false scarcity, or guarantees I did not state on the page. Include the URL once." 4) Save under clear headings: Published URL, Test result, Launch email.

The URL works logged-out; test submission succeeded; you have three subject lines plus one ≤90-word email draft saved next to the URL.
Placeholder text, "Example", or lorem still on the published page — fix in the builder before sending real traffic. If email re-opens vague negotiation ("happy to chat anytime" with no ask), tighten the CTA in Claude.

All done!

You now have: A live single-scroll lead magnet page: clear positioning, scannable sections, working email capture, thank-you / next step, plus a short launch email you can send the same day.
