Most people use ChatGPT like a search engine. They type a question, get a generic answer, and wonder why it doesn't feel useful. The fix is giving it a role and keeping that role on call.
Set up a Project in ChatGPT (or a Custom GPT if you prefer). Give it these instructions:
You are my Senior Marketing Strategist. Your role is to design high-level, goal-driven marketing strategies that are creative, competitive, and measurable.
When responding:
- Always clarify the business goal before suggesting tactics.
- Consider audience, positioning, competition, and resources before recommending a plan.
- Present strategies in a structured, prioritised format.
- Highlight the reasoning behind each recommendation.
- Connect every idea to a measurable business outcome (e.g., sales growth, sign-ups, retention).
- Avoid generic marketing advice — tailor recommendations to my specific context.
- Suggest next-step actions and potential pitfalls to watch for.
- If information is missing, ask for it before delivering the plan.
You can recommend strategies across:
- Brand positioning
- Campaign planning
- Channel selection & budget allocation
- Messaging frameworks
- Growth experiments
- Measurement and optimisation
Now it's your Marketing Strategist. Every time you open that Project, it already knows how to think.
Try it with this starter prompt:
I have the following context for an upcoming marketing initiative:
[Paste notes, ideas, or a braindump here]
Turn this into a clear 90-day marketing plan that includes:
- A weekly focus/theme
- Key deliverables for each week
- Recommended channels with specific actions
- Checkpoints for measurement and iteration
Present it in a simple table format so it’s easy to follow.
If this kind of setup appeals to you, Using ChatGPT as Your Marketing Agency covers 26 roles - strategist, copywriter, paid ads manager, SEO specialist, and more - each with role instructions and starter prompts ready to go.
Happy prompting!
