The Best Prompt for Copywriting
The best prompt for copywriting separates deciding what to say from deciding how to say it. This one has the model write a short message strategy first: the value proposition and the beliefs a buyer needs before acting, each matched to proof you supplied. It then writes the page block by block in that order. You get labeled page copy, three alternative headlines and a list of claims that still need evidence.

# Role You are a conversion copywriter. You decide what a page has to say before you decide how to say it, and you treat every claim as something a skeptical buyer will test. # Brief - Page type: [Page type] - What is being offered: [What is being offered] - Who the page is for: [Who the page is for] - The one action the page should get: [The one action] - Hesitations I hear from buyers: [Buyer hesitations] - Voice: [Voice] # Proof I can stand behind <proof> [Proof you can stand behind] </proof> # Task Work in two stages and show both. Stage 1: message strategy (keep it short) - What this reader already knows and wants when they land on the page, and what they are comparing the offer against. - The value proposition in one sentence: who it is for, what they get, and why this offer rather than the alternative. - The three or four things the reader must believe before they act, in the order they need to hear them. Match each belief to an item of proof above, or mark it UNSUPPORTED. Stage 2: page copy Write the page top to bottom, one block per belief, in that order. Include: - A headline and subheadline that state the offer and who it is for. A visitor who reads nothing else should know what this is. - Body sections that lead with the outcome for the reader, then the feature that produces it. - Each hesitation answered at the point on the page where it would come up, not saved for an FAQ. - One primary call to action, repeated with the same wording. Button text names what happens next. - A short line near the call to action that reduces risk, only if the brief supports it. # Constraints - Use only the proof supplied. No invented testimonials, customer names, numbers, guarantees, awards or deadlines. Where proof is missing, write [PROOF NEEDED: what would work here]. - No urgency or scarcity I did not give you. - Prefer the specific claim to the superlative. If a sentence could sit on a competitor's page unchanged, rewrite it or cut it. - Write the way this audience talks about the problem. Leave out category jargon they would not use themselves. # Output format 1. Message strategy. 2. Page copy, each block labeled with its purpose (for example Hero, Problem, How it works, Proof, Objection, Call to action). 3. Three alternative headlines, each taking a different angle, with the angle named. 4. Gaps: every UNSUPPORTED belief and [PROOF NEEDED] marker, and what I should collect to fill it.
Use it when you are
- Writing a landing page or homepage for a product or service launch
- Rewriting a sales or pricing page that describes features but gives no reason to act
- Drafting sign-up or demo-request page copy for a designer to lay out
- Checking whether you have enough proof to support the claims you want to make
Why this prompt works
Strategy is a visible first stage
Asked for landing page copy directly, a model reaches for a familiar hero, three benefit cards and a testimonial strip. Making it state the reader's starting point, the value proposition and an ordered list of beliefs first means the page structure comes from this buyer's reasoning. Because the stage is shown, you can disagree with the logic before judging the wording.
Beliefs are matched to proof, one by one
A claim with nothing behind it is where copy turns into puffery. Pairing each belief with a supplied proof item, or the label UNSUPPORTED, exposes the weak points in your offer as well as the draft. The gaps section then tells you what to go and collect, which is often more useful than the copy.
Hesitations are handled where they arise
Objections saved for an FAQ at the bottom get answered after the reader has already left. Instructing the model to address each hesitation at the point it would come up places reassurance next to the claim that triggers the doubt, the way an experienced salesperson handles it in conversation.
The competitor test filters out generic lines
The rule that a sentence must be rewritten or cut if it could sit on a competitor's page unchanged gives the model a concrete check for specificity. It works better than asking for copy that is unique, because it describes how to tell and what to do about it.
How to use it
- Describe the offer in plain terms, including price or terms if the page will show them.
- List buyer hesitations in the customers' own words. Pull them from sales calls, support tickets or reviews rather than guessing.
- Paste only proof you could show a lawyer: documented numbers, testimonials with permission, real guarantees.
- Read stage 1 before the copy. If the belief order is wrong, say which belief should come first and ask for the page to be rewritten.
- Go through the gaps list and decide for each item whether to collect the proof or drop the claim.
- Put the final copy into your page layout and read it on a phone; cut any block that does not earn its screen.
AI model compatibility
| Model | Status | Notes |
|---|---|---|
| ChatGPT | Expected to work | Ask for stage 1 on its own first if you want to approve the belief order before any copy is written, then reply with any changes and ask for stage 2. |
| Claude | Expected to work | Proof is wrapped in XML-style tags so it stays distinct from the instructions, in line with Anthropic's prompting guidance. Add customer quotes inside the same tags. |
| Gemini | Expected to work | Keep the two stages and the output format as written; Google's guidance recommends clear structure and explicit output instructions. |
“Expected to work” means the prompt uses plain, model-independent structure and has been reviewed for that — not that it has been run on that model. A model is marked Tested only when a test record is published below.
Worked example
Scenario: A fictional payroll product for restaurants preparing a trial landing page. The inputs are illustrative.
# Role You are a conversion copywriter. You decide what a page has to say before you decide how to say it, and you treat every claim as something a skeptical buyer will test. # Brief - Page type: Landing page - What is being offered: Tallyroll: payroll software built for restaurants. Handles tip pooling, split shifts and staff who work at more than one location. $6 per employee per month, no setup fee. - Who the page is for: Owners of independent restaurants with 15 to 60 staff who currently run payroll themselves or through a bookkeeper - The one action the page should get: Start a 30-day free trial - Hesitations I hear from buyers: Switching mid-year is a mess. Will it really handle our tip pool rules? I already pay my bookkeeper for this. - Voice: Plain and direct # Proof I can stand behind <proof> - Imports year-to-date payroll history from a spreadsheet during setup - Tip pooling rules configurable by role and by shift - Integrates with two named point-of-sale systems (to be listed) - Testimonial with permission from a cafe owner: 'Payroll used to be my Sunday night. Now it is about twenty minutes.' - 30-day trial, no card required </proof> # Task Work in two stages and show both. Stage 1: message strategy (keep it short) - What this reader already knows and wants when they land on the page, and what they are comparing the offer against. - The value proposition in one sentence: who it is for, what they get, and why this offer rather than the alternative. - The three or four things the reader must believe before they act, in the order they need to hear them. Match each belief to an item of proof above, or mark it UNSUPPORTED. Stage 2: page copy Write the page top to bottom, one block per belief, in that order. Include: - A headline and subheadline that state the offer and who it is for. A visitor who reads nothing else should know what this is. - Body sections that lead with the outcome for the reader, then the feature that produces it. - Each hesitation answered at the point on the page where it would come up, not saved for an FAQ. - One primary call to action, repeated with the same wording. Button text names what happens next. - A short line near the call to action that reduces risk, only if the brief supports it. # Constraints - Use only the proof supplied. No invented testimonials, customer names, numbers, guarantees, awards or deadlines. Where proof is missing, write [PROOF NEEDED: what would work here]. - No urgency or scarcity I did not give you. - Prefer the specific claim to the superlative. If a sentence could sit on a competitor's page unchanged, rewrite it or cut it. - Write the way this audience talks about the problem. Leave out category jargon they would not use themselves. # Output format 1. Message strategy. 2. Page copy, each block labeled with its purpose (for example Hero, Problem, How it works, Proof, Objection, Call to action). 3. Three alternative headlines, each taking a different angle, with the angle named. 4. Gaps: every UNSUPPORTED belief and [PROOF NEEDED] marker, and what I should collect to fill it.
What a good response should contain
- A one-sentence value proposition that names restaurant owners and the tip and shift problem, not payroll software in general
- An ordered list of beliefs such as: it handles tips correctly, switching mid-year is manageable, it is worth the cost next to a bookkeeper, with the last likely marked UNSUPPORTED
- The mid-year switching worry answered next to the setup section using the history import, not in a closing FAQ
- The cafe owner's quote used word for word and no additional testimonials
- A gaps list asking for proof such as time or cost comparisons against a bookkeeper

Limitations and things to check
- The model cannot know which message will convert. Treat the headlines and belief order as hypotheses to test with real traffic.
- Claims about pricing, guarantees and results may carry legal requirements in your industry. Have them reviewed before publishing.
- It writes words, not layout. A designer still needs to decide hierarchy, imagery and what fits above the fold.
- If your stated objections are guesses, the copy will answer the wrong worries. Customer language makes the largest difference to the result.

Frequently asked questions
What if I do not have testimonials or numbers yet?
Say so in the proof field and list what you do have: how the product works, a trial, a refund policy, your own background. The prompt will mark the remaining beliefs UNSUPPORTED and suggest what to collect. A page that is honest about being new usually reads better than one propped up by vague claims.
Does this work for long sales pages as well as short landing pages?
Yes. The belief list sets the length: a low-cost, low-risk offer may need three blocks, while an expensive or unfamiliar one needs more beliefs established and more proof. Choose the page type that fits and let the strategy stage determine how many sections follow.
How is this different from the ad copy prompt?
Ad copy has to earn a click in a few words and a fixed format. Page copy has room to build a case and answer doubts. Use this prompt for the page the ad leads to, and keep the promise in the ad and the page headline consistent.
