How to use ChatGPT for marketing: practical prompts and examples
Kahu team·Updated 1 Oct 2026·7 min read
ChatGPT is most useful for marketing when you give it your real material: who your customers are, what you sell, how you sound and what you want people to do. Ask it for several options, pick one, and edit. Use it for first drafts, variations and research summaries, and keep a person checking facts, prices and promises.
Give it a brief first
Most weak AI copy comes from a weak prompt. Save a short brief and paste it at the start of each chat, or store it in a project.
- What you sell, in one sentence.
- Who buys it and what problem they have.
- Three phrases you would use and three you never would.
- Your prices, service area and booking method.
- The one action you want readers to take.
Prompts that work
- 1Ad headlines“Using the brief, write 10 Google Ads headlines under 30 characters for people searching for [service] in [town]. Vary the angle: speed, price, trust, result.”
- 2Social posts“Turn these job notes into three Instagram captions: one short, one story-led, one with a question. End each with how to book.”
- 3Follow-up emails“Write a friendly follow-up for a quote sent five days ago. Under 80 words. No pressure. Offer a quick call.”
- 4Landing page“Draft a landing page for [offer]: headline, three benefits, what happens next, and an FAQ of five real objections.”
Edit like an editor
Read every draft as if a customer wrote in to complain about it. Remove anything you cannot back up. Replace general claims with specifics: a suburb, a turnaround time, a real result. If it would fit any business in your industry, it is not finished.
Where ChatGPT is weaker
- Current prices, rules and platform limits, which change faster than its knowledge.
- Knowing what worked for your business before, unless you tell it.
- Judging what is true about your competitors.
Frequently asked questions
Will Google penalise content written with ChatGPT?
Google’s guidance focuses on whether content is helpful and original, not how it was produced. Thin, mass-produced pages are the problem.
Can ChatGPT run my social media?
It can draft and plan. Posting and replying still benefit from a person who knows the customers.
Is the free version enough for marketing?
For drafts, often. Paid plans add higher limits, file uploads and projects that remember your brief.
