AI Social Media Plan for Small Business: A 30-Day Content Calendar and Copy-Paste Prompts

Most small-business owners don't run out of things to post about. They run out of time to decide what to post, write it and remember to publish it. Free AI tools such as ChatGPT, Google Gemini and Microsoft Copilot can take most of that work off your plate: they can turn one short description of your business into a month of post ideas, draft captions in your voice, reshape one post for several platforms and help you read your results. This guide gives you a simple 30-day plan, a ready-made calendar and the prompts to fill it in about an hour a month.

Short answer: write a short business brief once (what you sell, who to, where, your tone and what's coming up this month), paste it into an AI assistant and ask for a 30-day plan of about three posts a week across four content pillars: teach, show, prove and offer. Then batch-write the captions in one sitting, add your own photos, schedule the posts, and spend 10 minutes a week replying to comments. AI drafts; you check every fact, price, offer and photo before anything goes out.

Replace anything in [brackets] with your details. The prompts work in the free versions of the main AI assistants.

What AI does well in social media, and what it doesn't

Step 1: Write your business brief (once)

Everything AI writes for you is only as good as what you tell it. Write this brief once, save it in a note on your phone, and paste it at the start of every planning session. Many AI assistants also let you save instructions or memory so you don't have to paste it every time.

Business brief template:

"Business: [name], a [type of business] in [town/area, country]. We sell: [main products or services, with price ranges]. Our best customers are: [who they are and what they care about]. What makes us different: [2–3 true facts, e.g. same-day call-outs, 15 years' experience, family-run]. Tone: [friendly and plain / professional / playful]. Words we never use: [list]. Platforms: [e.g. Instagram, Facebook, LinkedIn, TikTok, Google Business Profile]. This month: [launches, offers with exact terms and end dates, events, holidays, quiet days we want to fill]. Goal this month: [e.g. more bookings for Tuesdays / enquiries for a new service / reviews]."

Be specific about the goal. "More followers" is hard to act on. "Five more bookings on quiet weekdays" gives the AI something to plan around.

Step 2: Pick four content pillars

A content pillar is a theme you come back to every week, so you never start from a blank page. Four pillars work for almost any small business:

The split is a starting point, not a rule. If you only ever post offers, people tune out. If you never post offers, people don't know they can buy. Adjust it after your first month based on what got comments, messages and bookings.

Step 3: Your 30-day calendar (ready to fill in)

Three posts a week is realistic for most owners and enough to stay visible. Use the same days every week so it becomes a habit. Here's a 12-post calendar built on the four pillars. Add a quick story or status update on other days if you have something to show.

Fill in the details with prompt 1 below, then write the captions with prompts 3 to 10.

The prompts

Plan the month

1. "[Paste business brief.] Create a 30-day social media plan with 3 posts a week on Monday, Wednesday and Friday, starting [date]. Use four pillars: teach (useful tips), show (behind the scenes), prove (real results and reviews) and offer (what we sell). Give each post a date, pillar, platform, format (photo, carousel, short video or text), a one-line idea and the photo or video I need to take. Put it in a table. Don't invent offers, prices or customer stories: write [placeholder] where I need to add real details."
2. "Here are the 20 questions customers ask us most: [list]. Turn each one into a teach-post idea with a hook (the first line people see) of under 10 words."

Write the captions

3. "Write the caption for post [number] in the plan. Start with a hook of under 10 words, keep it under [80/150] words, use short lines that are easy to read on a phone, and end with one clear call to action: [book via link / send us a message / visit us at address]. Use our tone from the brief."
4. "Give me 5 different hooks for this post and say which type each one is (question, bold statement, number, mistake, before-and-after): [post idea]."
5. "Rewrite this caption so it sounds like me talking to a regular customer, not like an advert. Remove any clichés like 'elevate', 'unlock' or 'game-changer': [paste caption]."
6. "Write a carousel post (6 slides) on [topic]: a slide-1 headline under 8 words, 4 slides with one tip each in under 20 words, and a last slide with a call to action. Then write a short caption to go with it."
7. "Write a 30-second video script for [topic] that I can film on my phone in one take at [place]. Include what to show in each shot, what to say, and on-screen text. No music or trends I'd need to licence."
8. "Give me a list of 10 photos I can take this week at [business] that would work for the posts in my plan. For each one, say the angle, the light and what should be in the frame."
9. "Write the offer post for [offer], including the exact terms: [price, what's included, start and end date, any conditions]. Don't add anything I haven't listed, and don't use 'limited time' unless I've given an end date."
10. "Suggest 5 to 8 relevant hashtags for this post: a mix of local ([town]), industry ([industry]) and topic tags. Avoid very broad tags with no connection to my customers."

Reuse one post across platforms

11. "Turn this Instagram caption into: a Facebook post, a LinkedIn post in a more professional tone, a Google Business Profile update under [100] words with a [Book/Call/Learn more] button idea, and a WhatsApp Status line. Keep the facts exactly the same: [paste caption]."
12. "Turn this blog post or FAQ answer into 3 short social posts, each with a different hook: [paste text]."
13. "Turn this customer review into a 'prove' post idea. Quote it word for word, don't change or add to it, and suggest a photo to go with it: [paste review]. (I'll ask the customer before using their name.)"

Engage and reply

14. "Write 5 friendly replies to positive comments on our posts that don't all sound the same. Each under 20 words."
15. "A customer commented this on our post: [comment]. Draft a short, calm public reply and a suggested private message to sort it out. Don't admit fault or promise a refund; I'll decide that."
16. "Write 5 questions we can ask our followers in posts or stories to get comments, related to [topic/season]. Avoid anything that asks for personal information."

Seasonal and local posts

17. "List holidays, school-holiday periods, local events and seasonal moments in [country/region] between [dates] that are relevant to a [type of business]. Mark anything you're unsure of so I can check the date."
18. "Write 3 post ideas for [event or season] that link to what we sell without being pushy."

Review the month with your numbers

19. "Here are last month's posts with reach, likes, comments, shares, saves, link clicks and messages for each: [paste table from your platform's insights]. Which pillars and formats did best? Which 3 posts should we make again in a different way? Keep it to 5 bullet points."
20. "Based on this review, update next month's plan: keep the same days, but shift the mix of pillars and formats towards what worked. Show what you changed and why."
21. "Here are the messages and enquiries we got this month and which post each came from, where we know: [paste]. Which posts actually brought in customers, rather than just likes?"

Industry starters

22. Trades and home services: "Write 4 teach posts for a [plumber/electrician/builder] in [area] about problems homeowners can spot early, each ending with 'Send us a photo and we'll tell you if it needs a call-out.'"
23. Salons and beauty: "Write a week of posts for a salon launching [service]: one explaining what it is, one behind the scenes, one answering 'how long does it last?' and one booking post with our link."
24. Restaurants and cafés: "Write 3 posts for our weekly special, [dish, ingredients, price, days available]. Use only the ingredients I list and don't make health claims."
25. Coaches, consultants and professional services: "Turn these 3 lessons from client work into LinkedIn posts, without naming clients or sharing any detail that could identify them: [lessons]."

Step 4: Batch, schedule and step away

The time-saver isn't the AI alone. It's doing the month's work in one or two sittings instead of deciding what to post every morning.

1. Plan (15 minutes): run prompt 1 with your brief and edit the plan.
2. Write (20 minutes): draft all 12 captions with prompts 3 to 10, then read each one aloud and fix anything that doesn't sound like you.
3. Shoot (20 minutes): take the photos and short videos from your shot list in one go, in good daylight.
4. Schedule (10 minutes): load the posts into a scheduler. Meta Business Suite is free for Facebook Pages and connected Instagram accounts, and lets you schedule posts between 20 minutes and 29 days ahead, according to Meta's help page on scheduling posts for your Facebook Page. Its "Active times" option shows suggested times to post. For other platforms, check the platform's own scheduling feature or a scheduling tool's free plan.
5. Engage (10 minutes a week): reply to comments and messages. Scheduling saves time, but people still expect a person to answer.

Because Meta Business Suite only schedules up to 29 days ahead, it's easiest to schedule the month in one sitting at the start of each month.

The rules AI can't follow for you

• Check every fact. Prices, offer terms, dates, opening hours, phone numbers and links must be checked against your own records before posting. AI can repeat out-of-date details or invent plausible ones.
• Only real reviews and results. Never let AI write testimonials, invent customer stories or "results" you can't back up. Quote real reviews word for word, and ask before naming or tagging a customer.
• Get permission for photos of people. Ask customers and staff before posting photos or videos of them, and be extra careful with children. Never post anything showing customer addresses, number plates, documents or screens with personal details.
• Don't paste customer data into AI tools. Your business brief needs facts about your business, not customer names, phone numbers or messages. Remove personal details before you paste comments or enquiries into a prompt.
• Disclose paid and gifted posts. If you pay or gift something to someone in exchange for a post, advertising rules in many countries (for example the FTC in the US and the ASA in the UK) require the post to make that clear. Check the rules where you trade.
• Be careful with AI images. Don't use AI-generated pictures that look like your real food, work, premises or results. Some platforms also ask you to label realistic AI-generated images or video; check each platform's current rules.
• Competitions and giveaways have rules. Platforms have their own promotion rules and some countries regulate prize draws. Check both before you run one.
• Don't copy. Don't ask AI to reproduce another business's posts, or to use music, logos or characters you don't have rights to.

A 60-minute monthly routine

1. Update your brief with this month's offers, events and goal (5 minutes).
2. Review last month with prompts 19 to 21 (10 minutes).
3. Plan, write, shoot and schedule the month as in Step 4 (about 45 minutes, plus 10 minutes a week to reply).

Frequently asked questions

Can ChatGPT make a social media plan for my business?

Yes. ChatGPT, Gemini or Copilot can turn a short description of your business into a 30-day plan with post ideas, formats and captions in a few minutes. The quality depends on what you tell it, so give it a brief with what you sell, who your customers are, your tone, this month's offers and one clear goal. Then check every fact, price and date before you post.

How often should a small business post on social media?

There's no single right number, but posting consistently matters more than posting a lot. Three posts a week on the same days is a realistic starting point for most small businesses and easy to plan in one sitting. After a month, look at which posts brought in messages and bookings and adjust from there.

What should a small business post on social media?

Use four simple themes, or content pillars: teach (useful tips that answer customer questions), show (behind the scenes and your team), prove (real reviews and results, with permission) and offer (what you sell and how to buy). Rotating them keeps your feed useful without becoming one long advert.

Is it OK to use AI-written captions?

Yes, as long as what they say is true and they sound like you. Edit each draft, check every fact, price and date, and remove phrases you would never say. Don't let AI write reviews or customer stories, and be careful with AI-generated images that could be mistaken for your real work or products.

Can I schedule a month of social media posts for free?

Often, yes. Meta Business Suite lets you schedule Facebook Page posts and connected Instagram posts for free, up to 29 days ahead. Many other platforms and scheduling tools have free options with limits, so check the current free plan for each one you use.

How do I know if my social media plan is working?

Look past likes. Each month, note how many messages, enquiries, bookings or sales came from social media, and which posts led to them. Paste your numbers into an AI assistant and ask which pillars and formats worked best, then shift next month's plan towards them.
