How to Use AI to Write Your Small Business Marketing Plan in One Afternoon
Most small businesses don’t have a marketing plan. Not because they don’t know marketing matters — but because writing one feels like a project that needs a consultant, a workshop, and a week of evenings they will never find. These five ChatGPT prompts produce every section of a complete, specific, one-page marketing plan in a single afternoon. No agency. No blank page. No marketing degree required.
A marketing plan is not a document you write once and file away.
It is a decision about who you are trying to reach, where you will find them, what you will say, and how you will know if it is working. Most small businesses make these decisions implicitly — through accumulated habit, gut feel, and reacting to what competitors seem to be doing. The result is inconsistent marketing that does not compound, spread too thin across channels that do not convert, and communication that speaks to no one in particular because no one has ever defined precisely who “particular” is.
ChatGPT cannot know your market better than you do. What it can do is take the knowledge you already have about your business, your customers, and your competitors, and organise it into a clear, structured plan that actually gets used. These five prompts do that, in order, in a single afternoon.
Prompt 1 — The Target Customer Definer
Marketing that tries to reach everyone reaches no one. The most important decision in any marketing plan is defining precisely who you are trying to reach — specifically enough that you could describe the person to a stranger and they would know exactly who you meant. Most small businesses have a vague sense of this but have never written it down clearly. This prompt does it properly.
You are a marketing strategy advisor helping a small business owner define their ideal target customer precisely. My business: [Business name], a [brief description — e.g. "sole trader plumber in Leeds" / "hair salon with 3 staff in Bristol" / "independent café in Manchester"] that has been trading for [X years]. My current customers (describe the typical person who buys from me): [Brief description — as rough as you like] My best customers (the ones I love working with and who get the best results): [Brief description — if different from above] Services or products I most want to grow: [e.g. "the colour services, not the basic cuts" / "commercial clients not domestic" / "walk-in coffee trade not table bookings"] Build me a specific, realistic ideal customer profile covering: 1. DEMOGRAPHICS — Age range, likely occupation, household situation, approximate income level 2. PSYCHOGRAPHICS — What they care about, what worries them, what they aspire to 3. THE TRIGGER — What specific event or problem causes them to search for a business like mine? 4. THE DECISION — What makes them choose one business over another? What are they really buying when they choose me? 5. WHERE THEY ARE — Where do they spend time online and offline? Where will marketing reach them? 6. WHAT PUTS THEM OFF — What would make them not choose me or a business like me? Be specific — avoid phrases like "men and women aged 25-65." Real profiles have real detail.
Prompt 2 — The Competitive Positioning Statement
Positioning is not about claiming to be “the best” — every business says that. It is about being the clearest and most specific about who you are for and what you do differently. This prompt produces a positioning statement you can use across your website, your quotes, and your marketing materials.
You are a brand strategy advisor helping a small business owner define their competitive positioning. My business: [Business name], a [brief description]. My target customer (from Prompt 1): [Copy the key points from the profile above] My main competitors: [Describe 2–3 main competitor types — e.g. "larger national chains like X", "cheaper local sole traders", "online alternatives that undercut on price"] What I believe makes my business genuinely different: [Be honest — not "great service" but specific things like "I use premium materials", "I guarantee my work for 12 months", "I only take 4 clients at a time so service is personal", "I respond to enquiries within 2 hours"] What I am NOT: [e.g. "I am not the cheapest option and I don't try to be" / "I am not a franchise with call centre service" / "I am not a volume business that rushes jobs"] Produce: 1. A ONE-LINE POSITIONING STATEMENT — For [target customer], [Business name] is the [category] that [benefit] because [reason to believe]. Fill this template with specifics from my information. 2. A 2-SENTENCE VALUE PROPOSITION — For use on my website homepage or in my quotes. Specific, credible, never uses the phrase "quality service." 3. MY SINGLE STRONGEST DIFFERENTIATOR — The one thing, stated in one sentence, that I should lead with in every piece of marketing. Why this one, not the others. Be honest: if my positioning is weak, tell me what to strengthen before we proceed to the marketing plan.
Prompt 3 — The Channel Prioritiser
The most common marketing mistake small businesses make is spreading too thin — trying to be active on Facebook, Instagram, LinkedIn, TikTok, Google, and email simultaneously, doing all of them poorly. Two to three channels done consistently beat ten channels done intermittently every time. This prompt recommends the right 2–3 channels for your specific business, customer, and available time.
You are a marketing strategy advisor helping a small business owner choose the right 2–3 marketing channels for their business. My business: [Brief description] My target customer (from Prompt 1): [Key points from the profile] My positioning (from Prompt 2): [Key points] My marketing budget: £[X] / $[X] per month (or "zero — organic only") Time I can commit to marketing: [e.g. "1–2 hours per week" / "30 minutes per day" / "I want to batch it — one morning per week"] What I have tried before: [e.g. "Facebook page but posting inconsistently" / "nothing yet" / "paid Facebook ads once, didn't work well"] My goal for the next 6 months: [e.g. "more enquiries" / "more awareness in my local area" / "more repeat business from existing customers"] Recommend my 3 marketing channels. For each channel: 1. Why this channel for my specific business, customer, and goal 2. What success looks like in 6 months on this channel (realistic, not aspirational) 3. Minimum viable commitment — what I need to do to make this channel work without burning out 4. One mistake to avoid on this channel Then give me a 5th channel to add in 12 months' time once the first three are established. Be honest: if a channel I have tried has not worked, tell me why rather than just recommending I try harder.
Prompt 4 — The 90-Day Content Calendar
The single biggest barrier to consistent marketing is not running out of content ideas — it is the paralysis of starting from scratch every week. A 90-day content calendar eliminates that paralysis. This prompt produces 13 weeks of content themes and specific post ideas for your chosen channels, based on your target customer, your positioning, and your business.
You are a content marketing advisor helping a small business owner build a 90-day content calendar. My business: [Brief description] My target customer: [Key points from Prompt 1] My channels (from Prompt 3): [Your 2–3 chosen channels] My posting frequency: [e.g. "3 times per week on Facebook and Instagram" / "once per week email newsletter and daily Instagram Stories" / "2 times per week across all channels"] Build a 90-day content calendar (13 weeks) covering: - One WEEKLY THEME for each of the 13 weeks — specific to my business type and audience, not generic marketing themes - For each week: 3 specific post ideas that match the theme — one educational, one engagement-driving, one commercial (promotes a service or offer) - For each post idea: a SPECIFIC OPENING LINE that could be used as the first sentence or hook Additional requirements: - Include 2 seasonal hooks relevant to my business type across the 90 days - Include 2 "transformation/showcase" post ideas — before/after, case study, or result posts - Include 1 "behind the scenes" post idea per month Do not use generic content marketing themes like "Motivation Monday" or "Throwback Thursday." Every theme and post idea should be specific to my type of business and my specific target customer.
Prompt 5 — The One-Page Plan Assembler
This final prompt pulls everything together into a single, clean, one-page marketing plan you can save, print, or share. The goal is a document you will actually use — short enough to be on one page, specific enough to guide real decisions, and clear enough that you could hand it to someone else and they would understand your marketing strategy immediately.
You are a marketing strategist helping a small business owner assemble a one-page marketing plan from the work we have done in this session. Using everything we have established in this conversation — the target customer profile, the competitive positioning, the chosen channels, and the content calendar themes — produce a ONE-PAGE MARKETING PLAN with the following sections: BUSINESS: [Name and one-line description] TARGET CUSTOMER: [2–3 sentences — the most important insights from the profile] OUR POSITION: [The one-line positioning statement and our single strongest differentiator] OUR CHANNELS: [The 3 chosen channels with the minimum viable commitment for each] WHAT WE WILL CREATE: [The 3 content types we will produce, with the weekly cadence] OUR 90-DAY FOCUS: [The single most important marketing priority for the next 90 days] HOW WE WILL MEASURE SUCCESS: [3 specific metrics we will track — not vanity metrics] WHAT WE WILL NOT DO: [2–3 specific marketing activities we are deliberately avoiding to stay focused] Format this as a clean, structured document I can save as a PDF or print. One page. Plain language. No marketing jargon. This should be a document I refer to every Monday morning, not one I file away and forget.
