How to Use ChatGPT for Social Media Posts: 15 Copy-Paste Prompts for Small Business

Why AI social posts sound like ads (and the 60-second fix)

You’ve seen them: “🚀 Elevate your experience! Unlock the magic of our amazing services! #blessed #smallbusiness #love.” Nobody stops scrolling for that. AI writes like that when it has to guess, so it fills the gaps with hype. The fix is to hand it the three things it can’t guess: your facts, your voice and one clear job for the post.

The easiest rule for posts people actually read: lead with something useful (a tip, a behind-the-scenes moment, an honest answer to a question you get a lot), and save the “book now” for the last line, or skip it.

Step 1: Set up your brand voice once (5 minutes)

Make one “Social posts” space that already knows your business. In ChatGPT that’s a Project:

1. Select New project in the sidebar and name it “Social posts.”
2. Open the project’s ••• menu, choose Project settings, and paste the voice card below into the instructions box. OpenAI says project instructions apply only inside that project.
3. Optional: add your menu, price list or service list as files. OpenAI lists 5 files per project on the Free plan and 25 on Go and Plus.

You write social media posts for [BUSINESS NAME], a [WHAT YOU DO]
in [TOWN]. Our customers are [WHO]. Our voice: [3 WORDS, e.g.
friendly, down-to-earth, a little funny].

Here are 3 posts that sound like us:
[PASTE 3 POSTS YOU OR A FAVORITE LOCAL BUSINESS WROTE]

Rules:
- Lead with something useful or interesting, not a sales pitch.
- Short sentences. Max 2 emojis and 3 hashtags per post.
- Never invent prices, sales, awards, reviews, customer quotes,
  numbers or results. If a fact is missing, write [CHECK].
- Never promise discounts, refunds or dates.
- Give me 3 options for every post, each a different angle.

Using Claude instead? Make a Claude Project and paste the same card into its instructions. Already set up a voice for emails? Reuse it: our email guide uses the same idea.

Step 2: A simple weekly plan (3 kinds of posts)

You don’t need a content calendar app. Rotate three kinds of posts and you’ll never stare at a blank box again:

Post on a schedule you can actually keep. Two or three good posts a week beat seven rushed ones.

Copy-paste prompts for social media posts

The 3 planning prompts are free here; Bot Club members get all 15. Paste these inside your “Social posts” project so the voice card is already loaded. Fill in the [BRACKETS].

Plan the week

1. Plan my next 7 days of posts for [PLATFORM]. Use the helpful /
behind-the-scenes / offer mix, max 2 offer posts. For each day give:
the idea in one line, the first sentence, and what photo I should take.
This week's news: [ANYTHING NEW, e.g. new item, holiday hours, event].

2. Interview me with 5 quick questions, one at a time, about what
happened at [BUSINESS] this week. Then turn my answers into 3
behind-the-scenes post ideas. Use only what I tell you.

3. List the 15 questions customers most often ask a [BUSINESS TYPE].
Mark the 5 that would make the most useful posts, and say why.

Make post pictures with ChatGPT Images

OpenAI’s help page says ChatGPT Images is available on all plans, including Free, on the web, iPhone and Android. Here’s how to use it for posts:

1. Ask in any chat (“Create an image of…”) or select More → Images. OpenAI says it can take a few minutes; you can keep chatting while it works.
2. Pick the shape. Use the aspect ratio picker, or say it in your prompt: square for feeds, tall 4:5 for Instagram, or 9:16 for Stories and Reels covers.
3. Start from a template. Open Images → Templates for starting points like posters, then fill in your details.
4. Edit one part. Select the image, use Select to highlight an area, and describe the change. OpenAI notes highlights aren’t always precise.
5. Fix up your own photo. Upload a real photo and describe the change, like a cleaner background. Every image you make is saved under Images, where you can copy, save or share it.

The rules: reviews, sponsored posts and fake followers

Social media marketing has a few legal lines, and AI makes them easy to cross by accident. Here’s what the FTC says, in plain English (not legal advice):

• No fake reviews or testimonials. The FTC’s rule on consumer reviews and testimonials took effect on October 21, 2024, and courts can impose civil penalties for knowing violations. Never have AI write a “customer” quote, and don’t put words in a real customer’s mouth.
• Don’t tie rewards to good reviews. The FTC says you can’t imply a review must be positive to get an incentive, and gives “Tell us how much you loved your visit… and get a $5 coupon” as an example of what not to say.
• Family and employee reviews need a clear disclosure of the relationship, like “my wife’s company.” The FTC says a disclosure at the start of a text post stands out.
• No fake followers. The rule covers buying fake indicators of social media influence (bot followers and the like) that you knew or should have known were fake.
• Got something free from a brand? If you post about a brand that paid you or gave you free or discounted products, say so right in the post, in plain words like “ad,” “sponsored” or “Thanks to Acme for the free product.” The FTC says not to bury it in a pile of hashtags or only on your profile page, and to put it in the video itself for video posts.

Privacy and good manners

• Ask before you post a customer’s name, photo or review. Use first names only.
• Never paste customer phone numbers, addresses, card numbers or passwords into an AI chat. No post needs them.
• Training setting: OpenAI says project content on Free, Plus and Pro may be used to train its models if Improve the model for everyone is on. You can turn it off in Settings → Data controls. More in Is my AI assistant safe?
• Read every post before it goes out. You’re the editor. AI can sound sure and still get a date or price wrong.

For freelancers and agencies: one project per client

Run social for other businesses? Make one Project per client with that client’s voice card, offers and banned words, so voices never mix. OpenAI says projects can be shared, so a client can review drafts inside the project (on Free you can share with up to 5 collaborators, on Plus and Go up to 10). More client-work ideas are on our page for freelancers and agencies.

When the posts still sound wrong

• Too salesy? Say: “Rewrite with zero sales words. Make the first line a tip a customer could use today.”
• Too many emojis or hashtags? Say: “No emojis. One hashtag, our town name.” Then put the limit in your voice card.
• Too long? Give a word limit (“under 40 words”), not “make it short.”
• Sounds like everyone else? Add one real detail only you know: a regular’s nickname, the street you’re on, what went wrong this morning.
• It invented something? Say: “List every fact in this post and where it came from.” Delete anything it can’t point to.
