How to Write Better AI Prompts: 7 Principles That Work

Oct 3, 2026 2 min read

The difference between a disappointing AI answer and a great one is usually the prompt. You don't need special tricks, just a few principles applied consistently.

1. Start with the goal

Say what you're trying to achieve, not just what you want written. “Write a LinkedIn post” is a task; “Write a LinkedIn post that gets hiring managers to message me about product design roles” is a goal.

2. Give context

The AI doesn't know your business, audience or situation unless you tell it. Who is this for? What do they already know? What's the background? A few sentences of context can transform the result.

3. Assign a role

“Act as an experienced recruiter” or “You are a patient maths tutor” sets the expertise and tone in one line.

4. Specify the format

Tell it exactly what you want back: a table with three columns, five bullet points, under 150 words, a subject line plus the email body. Format instructions are among the easiest wins.

5. Show an example

If you have a sample of the style you like, include it. Examples communicate tone and structure better than any description.

6. Set constraints

Say what to avoid: jargon, clichés, invented statistics, anything longer than a page. Constraints focus the output.

7. Iterate

Treat the first answer as a draft. Ask for changes: “shorter”, “more specific”, “give three alternatives”, “make the opening stronger”. Then save the improved prompt for next time.

A simple template

Act as [role].
Goal: [what you want to achieve].
Context: [background and audience].
Task: [what to produce].
Format: [length, structure].
Avoid: [constraints].
