Prompting Gemini well

Google publishes clear guidance on prompting Gemini, built around a simple, effective four-part structure. Learning it makes your results noticeably better — and it's just clear communication.

Google's four-part prompt formula. Google teaches four parts to a good prompt:

1. Persona — who Gemini should be, or who you are. 'You are a marketing analyst' or 'I'm a project manager.' This steers the tone and expertise.
2. Task — the specific action, with a clear verb. 'Summarize,' 'draft,' 'compare,' 'rewrite,' 'create a table.'
3. Context — the background, details, audience, and constraints. The more relevant context, the better.
4. Format — how you want the output structured. 'In a table with columns for X, Y, Z,' 'as a bulleted list,' 'a short email,' 'under 200 words.'

Google's own example: 'I'm a project manager (persona) and need to create a detailed project tracker (task) for a website redesign (context) in a simple table with fields for dates, status, and tasks (format).' Covering these four gets you a strong result.

Use natural language, be specific, iterate. Google's other tips: write naturally (like instructing a colleague), be specific with clear keywords, avoid jargon, break multi-part requests into separate prompts, and iterate — use each response to guide the next. Prompting is a conversation.

Ask for the persona, tone, and length you want. A practical Gemini note: recent Gemini tends to answer fairly concisely and directly by default. So if you want a specific voice, a warmer tone, or a longer, more detailed response, ask for it explicitly (this is the 'persona' and 'format' parts in action). Don't assume it'll be chatty or detailed unless you request it.

Reference your own data (@). As covered, in the Gemini app and Workspace you can '@'-mention your own Docs, Sheets, or emails to ground a prompt in your real content — a powerful way to give Gemini exactly the context it needs. And a handy trick: you can prefix a request with 'Make this a power prompt: [your prompt]' to have Gemini improve your prompt for you.

The takeaway: Google's guidance for prompting Gemini centers on a four-part formula — Persona (who Gemini is / who you are), Task (the specific action verb), Context (background, audience, constraints — more is better), and Format (how to structure the output). Covering these four gets strong results. Write naturally, be specific, avoid jargon, split multi-part requests, and iterate using each response. Because recent Gemini defaults to concise, direct answers, explicitly ask for a specific voice, tone, or longer detail if you want it (the persona and format parts). And use Gemini's data advantage — '@'-mention your own Docs, Sheets, or emails to ground prompts in your real content — plus the 'Make this a power prompt' trick to have Gemini improve your prompt.
