Build a Realistic 90-Day Marketing Plan From Zero, Solo, on a Small Budget
Most marketing plans read like an agency wrote them for a five-person team: three videos a week, daily content, ads running across four channels at once. A solo operator running their own business burns out on that plan in three weeks and quits. The real problem was never the ambition, it's building a rhythm you can actually sustain for 90 days with the capacity you really have. This prompt builds a plan from zero around a channel mix, a weekly action list, and clear criteria for when to say 'this isn't working, I'm cutting it' versus 'this is working, keep going,' all sized to what one person can genuinely pull off. It doesn't shrink an agency plan down, it builds the plan up from your actual capacity.
You're a growth advisor who builds realistic marketing plans for solo businesses. Your job isn't handing me an agency plan, it's building one sized to my real capacity (time, budget, skill) that I can genuinely sustain for 90 days: a channel mix, a weekly action list, and clear measurement and cut criteria. The plan should build a rhythm I can actually finish, not a fantasy. Use the following information: - Business / product: [what you sell, what you do] - Monthly marketing budget: [amount, can be zero] - Hours per week you can give to marketing: [hours] - Skills you have: [strong at writing, visuals, or video; what you're weak at] - Current state: [no customers yet, a few, repeat customers] - Your goal: [where you want to be after 90 days] - Anything you already tried that didn't work: [briefly, if any, so it doesn't get suggested again] RETURN THE OUTPUT IN THIS EXACT ORDER, WITH THESE EXACT HEADINGS: ═══ CHANNEL MIX ═══ Recommend 2-3 channels based on my stated skills and time (organic social, email, small-budget ads, marketplace SEO, etc.). Justify why you picked these channels, don't propose a mix that exceeds my capacity. If I mentioned something I already tried that didn't work, don't suggest it again. ═══ DAYS 1-30: FOUNDATION ═══ A weekly action list for the first 30 days (2-4 concrete items per week). State clearly what this period is for, and why jumping to testing before the foundation is set would be premature. ═══ DAYS 31-60: TEST ═══ A weekly action list for the second 30 days. Explain what I'm testing in this period and how it differs from the first period. ═══ DAYS 61-90: DOUBLE DOWN ═══ A weekly action list for the third 30 days. Explain how to scale up whatever worked in the first two periods, and why deepening what's already working beats starting a new channel in this window. ═══ MEASUREMENT CHECKPOINTS ═══ State the 2-3 metrics I should check at the end of every 30 days (sales, followers, email list growth, etc.). Name which metric to track, not a made-up target number. ═══ CUT AND CONTINUE CRITERIA ═══ Give clear criteria for when to cut a channel and when to put more resources into it. State why quitting too early and pushing too long are both risky. RULES: - No made-up growth numbers, no fake "you'll hit X sales in 90 days" promises. - Actually fit the plan inside the stated time and budget capacity, don't hand back an agency-scale plan. - Keep the channel count low, limited to what one person can genuinely manage. - If a method was already tried and failed, don't suggest it again, explain why a different approach is needed instead. - Write in clear, actionable, direct English.
How to use it
- Write down your business, your real monthly budget, the hours per week you can give to marketing, and the skills you actually have (can you write, can you shoot video) with total honesty. Overstate your capacity and the plan will wear you out, so keep it real.
- Run the prompt and get the 90-day plan. Read the first two weeks especially carefully and ask yourself if it's genuinely doable; if not, lower your weekly hours input and rerun it.
- Put the plan straight into your calendar and check the measurement checkpoints at the end of every week. If a channel hits the cut threshold, actually cut it. If a channel hits the double-down threshold, shift your resources into it.
Example / tip
Input: business is a handmade jewelry shop selling on Etsy. Budget is $100 a month. Weekly time is 6 hours. Skill is decent phone photography, weak video editing. The AI output puts the first 30 days into Etsy SEO and organic Instagram, the second 30 days into a small-budget Meta test, and the third 30 days into doubling down on whichever channel won. Every week gets 2-3 concrete actions, and by the end of week 4 the plan states exactly which metric to check and the threshold for continuing versus cutting.
Usage example
Copy the prompt as is, fill in the bracketed fields for your own business, and paste it into ChatGPT or Claude. The more concrete your input, the more useful the output. Take the first draft, ask for a one-sentence fix on whatever you don't like, then give it a final pass in your own voice.
When not to use it
This prompt is built for small-budget, solo operations; if you're running a multi-person marketing team or working with a real budget, this plan will hold you back unnecessarily, so scale up your inputs and rerun it.
Output quality checklist
- Do the weekly actions actually fit inside the stated time budget, or does it still read like an agency plan.
- Are the measurement checkpoints and cut/continue criteria concrete, or vague.
- Does the channel mix genuinely match the skill set stated (strong at writing vs. strong at video).
