How to Write Marketing Copy with Claude (Prompts)

Quick answer: To write marketing copy with Claude, brief it like you'd brief a real copywriter: who it's for, the problem, your offer, your real proof and the one action you want. Keep your voice guide in a project so it sounds like you, ask for a few angles before a full draft, then edit, check every fact and approve it yourself.

For years I wrote every email, every caption and every page on my own, usually late at night and usually rushed. Some of it was good. A lot of it never went out because I ran out of time. Today I talk and my assistant drafts, and nothing goes to a real person until I've read it and said OK.

That shift didn't happen because I found a magic prompt. It happened because I learned how to brief. So if you've been searching for how to write marketing copy with Claude, how to get AI marketing copy that doesn't sound robotic, or which AI copywriting prompts actually work for a small business, here's my process.

Can Claude write good marketing copy?

Yes, Claude can write good marketing copy when you give it a clear brief, your real voice and true details about your offer. Without those, it writes copy that is smooth, polite and easy to forget.

Anthropic's prompting best practices compare Claude to a brilliant new employee who doesn't know your norms yet. The more precisely you explain what you want, and why, the better the result. That's exactly how copywriting works with people too. A great copywriter who knows nothing about your customer will still miss.

What do you need before you ask Claude for marketing copy?

Before you ask Claude for marketing copy, you need a short copy brief: the one person it's for, the problem they feel, what you offer and what it costs, the proof you really have, the main objection and the one action you want them to take.

Here's the brief I'd fill out for any piece:

• Who: one specific person, not "small business owners."
• Problem: what they'd say about it in their own words.
• Offer: what they get, what it costs and how long it takes.
• Proof: real results, real reviews with permission, your real experience. If you don't have any yet, say so.
• Objection: the main reason they'd say no.
• Action: the one thing you want them to do next.

Keep that brief, your offers and your voice guide in one Claude project so you never paste them again. I show how in how to use Claude Projects for a small business. If you don't have a voice guide yet, build it first with how to create a brand voice with AI. It's the difference between copy that sounds like you and copy that sounds like everybody.

How do you write marketing copy with Claude step by step?

You write marketing copy with Claude by giving it your brief, asking for several angles first, choosing one, drafting one piece at a time, checking it against what makes an offer valuable and then editing and verifying every claim.

1. Share the brief. Paste it or point to it in your project.
2. Ask for angles, not a draft. "Give me five different hooks for this offer, each in one sentence, each from a different angle."
3. Pick one and draft. "Use hook three. Write a 150 word email in my voice. One call to action."
4. Run a value check. Alex Hormozi's value equation in $100M Offers is a helpful lens: dream outcome and likelihood of success on top, time and effort on the bottom. Ask: "Does this show the result, real proof, how fast and how easy? Where is it weak?"
5. Cut it down. "Cut this by 20 percent without losing the meaning."
6. Check the facts. "List every claim, number and promise in this copy." Then confirm each one yourself.
7. Read it out loud. If you'd never say it to a friend, change it.

What are good AI copywriting prompts for a small business?

Good AI copywriting prompts name the piece, the person, the length, the voice and the single action, and they tell the assistant what not to do. Here are five I'd start with, written for a Claude project that already holds your brief and voice guide.

• Home page headline: "Write ten home page headlines for the person in my brief. Under ten words each. Plain words. No hype."
• Follow up email: "Write a short follow up email to someone who asked about my offer last week but didn't buy. Warm, no pressure, one question at the end."
• Social post: "Turn this voice memo into a post that opens with a story, teaches one thing and ends with one question."
• Offer page section: "Write the 'Is this for you?' section of my offer page: four lines on who it's for and three on who it isn't."
• Ad draft: "Write three short ad drafts for this offer. Use only the proof in my brief. Mark anything you had to guess with [CHECK]."

How do you keep AI marketing copy honest?

You keep AI marketing copy honest by only using claims you can prove, never letting it invent reviews or results and never using pressure that isn't true. Faster writing doesn't change the rules.

The Federal Trade Commission's Advertising FAQ's: A Guide for Small Business lays out the basics: advertising must be truthful and not deceptive, you need evidence to back up your claims, and ads can't be unfair. AI doesn't know what you can prove. You do.

So these are my lines. No made up testimonials. No income or results promises. No "only three spots left" unless there really are three spots left. No countdown timers that reset. Proverbs says "Lying lips are an abomination to the Lord, but those who deal truthfully are His delight." I want my marketing to be something God delights in. And honestly, honest copy converts better with the kind of customers you actually want to keep.

How do you make copy from Claude sound less like AI?

You make copy from Claude sound less like AI by feeding it your real stories and phrases, banning the words you'd never use, asking for specifics instead of adjectives and editing the first and last lines yourself.

• Specifics beat adjectives. "Your site live on your own domain" beats "an amazing online presence."
• Stories beat claims. Give it a real moment from your week to open with.
• Keep a "never" list. Every overused word you hate goes in your voice guide.
• Vary the rhythm. Ask for some long sentences and some short ones. Like this.
• Own the first and last line. Those are the lines people remember, so write or rewrite them yourself.

This matters for search too. Google's Search team wrote in its guidance about AI generated content that it rewards helpful, original content however it's produced, and that using AI to game rankings breaks its spam policies. Your stories and your experience are what make a page worth ranking.

When the copy is ready, it needs a home. My guide on how to build a business with AI without being a tech person shows how the pages, emails and follow up fit together.

Frequently asked questions

Is it okay to use AI to write marketing copy?

Yes, as long as the copy is true and you stand behind it. Use AI to draft and edit, but check every claim, never let it invent reviews or results, and approve anything before it reaches a customer.

What is the best prompt for marketing copy?

The best prompt names the piece, the exact person it's for, the length, your voice and the one action you want. For example: write a 150 word email in my voice to someone who asked about my offer, with one call to action.

Can Claude write ads for my business?

Claude can draft ad copy from your brief and voice guide. You still need to check each claim, make sure you can prove it and follow the rules of the platform where the ad will run.

Will AI written copy hurt my website on Google?

Google has said it rewards helpful, original content however it is produced, and that using AI to manipulate rankings breaks its spam policies. Write to help real people and add your own experience.

Should I tell customers I use AI to write?

Many owners choose to be open about it, and I am. The bigger rule is that every word is true and approved by you. Your customers are trusting you, not the tool.
