How to Write AI Prompts for Local Business Website Copy

Ask an AI tool to "write a homepage for a plumber" and you'll get copy that could belong to any plumber in any city. Words like "elevate," "seamless," and "your trusted partner" show up, and nothing sounds like the actual business. The fix isn't a magic prompt. It's giving the AI real details, clear rules, and one section to write at a time. This guide shows you how.

Why AI website copy comes out generic

AI only knows what you tell it. When the prompt is vague, it fills the gaps with safe, average wording, and sometimes with made-up details like years in business or customer reviews. Generic copy usually comes from three missing pieces:

• Real facts: services, neighborhoods, hours, what makes the business different.
• A real audience: who calls them and what those people worry about.
• Rules: tone, length, reading level, and words to avoid.

If you need a prompt for building a whole site, see how to write a prompt for an AI website builder. This guide focuses only on the words on the page.

How to write AI prompts for local business website copy

1. Build a fact sheet first

Before you prompt anything, write down what's true about the business:

• Business name, city, and the neighborhoods or towns they serve.
• Main services or menu items, in the owner's own words.
• Hours, how customers book or order, and the main phone or booking link.
• Anything real that sets them apart: family-owned, same-day service, a signature dish, languages spoken.

In Locasly, the prospect panel already has the basics from Google Maps, like name, address, category, and rating. You can also use Prompt for any LLM builder to generate a copy-paste prompt for v0, Lovable, Bolt, or ChatGPT, then add your fact sheet to it.

2. Describe the customer, not just the business

Tell the AI who reads the site and what they want. "Busy parents nearby looking for a quick weeknight dinner" gives much better copy than "customers." Add one or two common questions or worries, like price, wait time, or parking.

3. Set the voice with rules and an example

"Friendly and professional" fits thousands of businesses, so it doesn't help much. Instead, give clear rules:

• Short sentences, plain words, about a 6th-8th grade reading level.
• A banned list: "elevate," "unleash," "seamless," "nestled," "in today's fast-paced world."
• One or two sentences the owner actually wrote, like a Facebook post or a reply to a review, so the AI can match how they talk.

4. Ban invented facts

This is the most important rule. Tell the AI to use only the facts you gave it. If something is missing, it should write a placeholder like [NEED FACT: years in business] instead of guessing. No made-up reviews, awards, prices, or stats.

5. Prompt one section at a time

Hero, services, about, call to action, and FAQ each have a different job. Asking for them one by one gets more focused copy, and you can give each a word limit.

You are writing website copy for a local business. Use ONLY these facts.
If something is missing, write [NEED FACT: ...]. Do not invent reviews,
awards, prices, or numbers.

Business: Rosa's Taqueria, a family-owned taqueria in Merced, CA
Serves: downtown Merced and nearby neighborhoods
Known for: handmade tortillas, al pastor, breakfast burritos
Hours: 7am-9pm daily. Order: walk-in or phone.
Customers: students, families, people on lunch break
Owner's voice: "Come hungry. We make the tortillas every morning."

Write the homepage hero section:
- 3 headline options, under 8 words each
- 1 subheadline, under 20 words, that mentions Merced
- 1 button label
Rules: short sentences, 6th grade reading level, no "elevate",
"unleash", "seamless", "nestled", or "culinary journey".

The business above is made up for this example. Swap in your own client's real details.

6. Ask for options, then pick and mix

Ask for two or three versions of headlines and CTAs. It's easier to choose and combine than to fix one weak draft. For services, ask for one short paragraph per service that answers "what is it, who is it for, and what happens next."

7. Write the FAQ from real questions

Give the AI the questions customers actually ask the owner, and ask it to answer using only your facts.

Using only the facts above, write short answers (under 40 words each)
to these customer questions:
1. Do you take orders over the phone?
2. Do you have vegetarian options?
3. Is there parking nearby?
If a fact is missing, write [NEED FACT: ...] instead of guessing.

8. Fact-check and edit before it goes live

Read every line against your fact sheet. Fill in or delete each placeholder, cut the first sentence if it says nothing, and read the copy out loud. Then have the owner approve it. They'll catch details you can't. If the copy needs changes after it's on the site, use follow-up prompts to edit the AI-generated website.

FAQ

Which AI tool is best for website copy?

Most chat-based AI tools can write good copy if the prompt has real details and rules. The input matters more than the tool.

How long should homepage copy be?

For most local businesses, keep it short: a headline, a one-line subheadline, a few short service blurbs, a short about section, and a clear call to action.

Can I use AI-written reviews or testimonials?

No. Only use real reviews from real customers, with permission. Tell the AI never to write testimonials.

Can Locasly write the copy for me?

Locasly's AI Website Generator drafts a full website mockup for a prospect, and you can use a custom prompt. You can also generate a copy-paste prompt for other AI builders. Either way, add real details and check the copy before it goes live.
