Writing Your First Prompt
A "prompt" is simply the instruction or question you type to ChatGPT. The quality of your prompt directly impacts the quality of the response.
Bad prompt: "Write something about marketing."
Good prompt: "Write a 300-word LinkedIn post about why small businesses should invest in content marketing in 2026. Use a conversational tone and include 3 actionable tips."
The key difference? Specificity. Tell ChatGPT the format, length, tone, audience, and topic.
5 Prompting Techniques That Work
- Be specific — Include details about format, length, tone, and audience
- Give context — "I'm a freelance designer pitching to enterprise clients..."
- Use role-playing — "Act as a senior marketing strategist with 15 years of experience..."
- Iterate — Ask ChatGPT to revise, expand, or adjust its response
- Use examples — "Here's an example of what I'm looking for: [example]"
