Use it when you are

  • Planning the next quarter's marketing for a small business or startup
  • Deciding which channels to drop when the team is spread too thin
  • Preparing a first strategy draft before a meeting with a founder, client or agency
  • Checking whether a revenue or lead goal is realistic for the budget available

Why this prompt works

Diagnosis comes before tactics

Most AI-generated marketing plans open with a list of channels. Requiring one named obstacle first, tied to a fact you supplied, gives every later section something to answer to. A plan built around a conversion problem looks very different from one built around an awareness problem, and the prompt makes the model commit to which it is.

Hard limits force choices

Strategy is mostly deciding what not to do. Capping channels at three, asking for one priority segment, and requiring two rejected channels with reasons stops the model from hedging across everything. The rejections are often as useful as the picks because they show the reasoning you can argue with.

Resources are treated as a constraint, not a footnote

Each channel has to be costed in money and weekly hours against the budget and team you entered. The prompt also gives the model explicit permission to say the goal is out of reach, which counters the tendency to produce an optimistic plan that quietly needs three times the staff.

Numbers can only come from you

Benchmarks and market-size figures are where invented statistics usually appear. The prompt bans them unless supplied and tells the model to write "baseline needed" where a number is missing, so gaps show up as gaps you can fill from your own analytics.

It ends with what could prove the plan wrong

Asking for the two riskiest assumptions and a cheap test for each turns the document from a finished-looking plan into a set of bets. That gives you a sensible first two weeks: run the tests before spending the larger part of the budget.

How to use it

  1. Write the goal as a single outcome with a number and fill in the real budget and hours available, even if they feel small.
  2. Under what you have tried, paste actual results from your analytics, ad accounts or email tool. Leave it blank if you have none; do not estimate.
  3. Run the prompt in a new conversation and read the diagnosis first. If the obstacle is wrong, correct it and ask for sections 2 to 8 again.
  4. Replace every "baseline needed" with your own figure, then ask the model to revise the objectives.
  5. Challenge one rejected channel if you disagree, giving your reason, and see whether the plan changes.
  6. Run the two assumption tests before committing the main budget.

Worked example

Scenario: An illustrative houseplant subscription business planning its next quarter with a small budget and a part-time founder.

Example: filled-in prompt
# Role
You are a marketing strategist who works with small teams and limited budgets. You choose a few things to do well instead of listing every available channel.

# Business facts
- Business and offer: Fernway, a subscription box of houseplants for apartment renters, $32/month
- Target customers: Renters aged 25-40 in large US cities, new to plant care
- Business goal for the period: Grow from 400 to 700 active subscribers
- Planning period: Next 90 days
- Budget and team: $2,500/month, one founder at 10 hrs/week plus a freelance designer
- Marketing tried so far and what happened: Instagram posts 3x/week (about 2,100 followers, few sign-ups); a referral offer that drives roughly a quarter of new subscribers; no email list activity
- Competitors or alternatives customers consider: Two larger plant subscription brands; buying plants at a local garden center

# Task
Build a marketing strategy for the planning period. Work in this order, because each step limits the next.

1. Diagnosis: in one short paragraph, name the main obstacle between this business and its goal (awareness, consideration, conversion, retention or pricing). Point to the fact above that supports it.
2. Priority segment: the one customer segment to focus on, and who you are deliberately not targeting this period.
3. Positioning: one sentence in the form "For [segment] who [need], [business] is the [category] that [difference], unlike [alternative]."
4. Objectives: two or three measurable objectives that ladder up to the business goal, each with its metric and how to measure it. Where I gave no baseline, write "baseline needed" instead of a number.
5. Channels: choose at most three. For each give why it fits the segment, the specific activity, the cost in money and weekly hours against the stated resources, and the earliest signal that it is working. Then name two channels you rejected and why.
6. Messages: three core messages, each tied to a customer need, with the proof the business must be able to show.
7. Action plan: split the planning period into three phases with tasks, owner role and deliverable.
8. Riskiest assumptions: the two beliefs this plan depends on most, with a cheap test for each.

# Constraints
- Use no market-size figures, industry benchmarks or conversion rates unless I supplied them.
- Mark anything you had to guess with [ASSUMPTION].
- The plan must fit the stated budget and team. If the goal is out of reach with those resources, say so plainly and propose a smaller goal.
- No advice that would apply to any business, such as "build brand awareness" or "post consistently".

# Output format
Use the eight numbered headings. Put channels and the action plan in tables. Keep the whole response under 900 words.

What a good response should contain

  • A diagnosis that picks one obstacle and cites a supplied fact, for example the gap between Instagram following and sign-ups
  • One priority segment with a clear statement of who is left out this quarter
  • No more than three channels, each with a dollar and hours cost that adds up to within the stated budget, plus two rejected channels
  • Objectives that say "baseline needed" where figures such as churn or site conversion were not provided
  • Two assumptions with small tests, such as whether the referral offer still performs when promoted more actively

Limitations and things to check

  • The model knows only what you type. It cannot see your analytics, margins or customer conversations, so the diagnosis is a hypothesis.
  • Cost and time estimates for channels are rough. Check them against real quotes and your own past spend.
  • It does not research competitors. Anything it says about them beyond what you supplied should be treated as a guess and verified.
  • A strategy this short leaves out execution detail. Use the channel-specific prompts to build out each chosen activity.

Frequently asked questions

How is this different from asking for a marketing plan?

A plan lists activities. This prompt asks for the reasoning that comes first: what is blocking growth, who to focus on and what to ignore. The action plan appears only in step seven, after those choices are made, so the activities follow from a stated diagnosis you can check.

What if I do not have any marketing data yet?

Leave the results field blank. The model is instructed to mark assumptions and to write "baseline needed" instead of inventing figures. Expect a plan weighted toward cheap tests in the first phase, and plan to rerun the prompt once you have a few weeks of real numbers.

Can I use it for a B2B company?

Yes. Describe the buyer and the buying process in the target customers field, including who else signs off on a purchase and how long a typical sale takes. Those two facts change the channel choices and the timing of the objectives considerably.
