Optimising your marketing strategy with better AI prompts

The quality of AI output depends entirely on the input you provide. A poorly formulated prompt delivers generic results, while a sharp question can give you exactly what you are looking for. For entrepreneurs and marketers who want to save time and achieve better results, prompt engineering has become an essential skill.

Why prompt quality makes the difference

AI tools such as ChatGPT, Claude or Gemini are powerful, but they lack context and intuition. They interpret literally what you ask, without reading between the lines. A vague question delivers a vague answer. A specific, goal-oriented prompt generates output you can use directly.

“The quality of AI output depends entirely on the quality of the prompts you give — garbage in, garbage out applies here more than ever”

— Sam Altman, CEO OpenAI

The ROCKET formula for effective prompts

Instead of asking questions at random, use this structured approach:

• Role, Who should the AI be?
• Order, What needs to happen?
• Context, For whom and in what situation?
• Quality requirements, What specifications?
• Example, Give an example (optional)
• Tone, Which tone and style?

Example of the ROCKET formula in action

Poor: “Write a text about lead generation”

• Role: You are a B2B marketing consultant with 10 years of experience.
• Order: Write a practical guide of 800 words.
• Context: For Belgian SMEs in the technology sector that struggle with lead quality.
• Quality requirements: Use 5 concrete tactics, each with a practical example.
• Tone: Professional but accessible, avoid jargon.

“The difference between a good and bad AI result often lies in one or two words in your prompt — specificity is everything”

— Andrej Karpathy, Ex-Director of AI at Tesla

Advanced prompt techniques that work

1. Chain of thought prompting

Let the AI reason step by step by adding “think step by step”.

Example: You are an e-commerce consultant. A Shopify shop has 2% conversion but the sector average is 3.5%. Analyse step by step which factors could cause this and give 3 priority improvement actions.

For more tips about conversion optimisation, read our article about CRO in 2026 with AI and personalisation.

2. Few-shot prompting

Give examples of desired output.

Example: You are a copywriter. Write product descriptions in this style:

Example 1: “This organic coffee from Colombia awakens your senses. Each sip brings you the warmth of the Andean mountains.”

Example 2: “Handmade soap with lavender. Your skin feels soft, your bathroom smells like Provence.”

Now your version for: eco-friendly bamboo toothbrushes.

3. Persona prompting

Let the AI answer from a specific perspective.

Example: You are Emma, 34, marketing manager at a scale-up with 50 employees. You have a limited budget but need to show results. Which 3 marketing channels would you prioritise and why?

Common mistakes and how to avoid them

Mistake 1: Staying too general

Wrong: “Make a marketing plan”

Better: “Make a 90-day lead generation strategy for a B2B SaaS startup with €10k monthly budget”

Mistake 2: Not specifying output format

Wrong: “Give tips for SEO”

Better: “Make a checklist with 10 SEO actions for local businesses, each with expected impact (high/medium/low)”

For local businesses specifically, read our article about local SEO in Belgium.

Mistake 3: Forgetting context

Wrong: “Write a product launch post”

Better: “Write a LinkedIn post for the launch of our new CRM module, aimed at sales managers in the Benelux”

Mistake 4: Not planning iteration

Always start with “Version 1:” and ask for feedback to refine.

The RACE model for structured prompts

Another powerful method is the RACE model, specially developed for marketing prompts:

• Reach, Who do you want to reach?
• Act, What action needs to happen?
• Convert, What is the desired result?
• Engage, How do you keep attention?

Read more about this model in our article about the RACE model for ChatGPT prompts.

Prompt optimisation for different AI tools

ChatGPT-specific tips

• Use “Act as…” for role clarification
• Ask for source references with “Include sources”
• For creativity: increase temperature in settings

Claude advantages

• Excels in long documents and analysis
• Give more context, Claude can handle that better
• Ask explicitly for structure and formatting

Gemini strengths
