What’s a Prompt? AI Prompts Explained

The instruction, question or input given to a generative AI model to produce a response.

Definition

A prompt is the text, question or instruction you give a generative AI model — such as ChatGPT, Gemini or Claude — to get a response. It can be a single question or a detailed brief with context, examples and the format you want, and its quality largely determines the quality of the output.

Prompt examples

  • Simple: “What is a meta description?”
  • With context: “I run a dental practice in Leeds. Suggest five blog topics patients search for before booking Invisalign.”
  • With format: “Summarise this article in three bullet points under 20 words each.”
Five cards showing the parts of an effective AI prompt: role, task, context, examples and format
Not every prompt needs all five parts, but adding context and format usually improves results dramatically.

What makes a good prompt

  • A clear task — say exactly what you want done.
  • Context — audience, goal, background and constraints.
  • Examples — show the style or structure you expect.
  • Output format — length, tone, bullet points, table or JSON.
  • Iteration — refine based on the first answer rather than expecting perfection immediately.

The practice of designing prompts to get reliable results is called prompt engineering.

Types of prompts

  • Zero-shot — a task with no examples.
  • Few-shot — a task with a handful of examples to copy.
  • System prompt — background instructions set by an application that shape every response.
  • Multimodal prompt — combines text with images, audio or files.

Why prompts matter for marketing and SEO

People increasingly research products by asking AI assistants instead of typing short keywords into Google. Those prompts are longer, more conversational and more specific: “which CRM is best for a 10-person sales team that uses Gmail?” rather than “best CRM”. For businesses this means:

  • Content should answer full, specific questions, not just match keywords.
  • Brands need to be mentioned and trusted across the web for AI tools to recommend them.
  • Tracking which prompts mention your brand in ChatGPT, Gemini, Perplexity and Google AI Overviews is becoming a core part of generative engine optimisation (GEO).

Prompting techniques that improve results

  • Be specific: define audience, goal, constraints and length.
  • Provide source material: paste the brief, data or page content you want used.
  • Show examples of the output style you want (few-shot prompting).
  • Break complex tasks into steps and ask for one step at a time.
  • Ask for options and then refine the best one.
  • Request a check: ask the model to flag assumptions or missing information.

Prompt mistakes to avoid

  • Vague requests with no context or audience.
  • Trusting statistics or facts without verifying them against sources.
  • Pasting confidential customer data into tools without approval.
  • Publishing AI output without expert review and editing.
  • Asking for too many unrelated tasks in one prompt.

How businesses can track prompts about their brand

Create a list of prompts buyers might use, such as “best accountant for small businesses in Manchester” or “[your brand] reviews”. Test them monthly in ChatGPT, Gemini, Perplexity and Google AI Mode, and record whether your brand appears, how it is described and which sources are cited. Improvements to content, reviews and third-party coverage can then be measured over time. Our GEO playbook explains this process.

Prompts vs search keywords

Search keywordAI prompt
Typical length2–5 wordsOften a full sentence or paragraph

ContextLittlePersonal details, constraints, preferences
Expected outputList of linksA complete answer or recommendation
Follow-upsNew searchContinues in the same conversation

A reusable prompt template

You are a [role]. Your task is to [task] for [audience]. Context: [background, goal, constraints]. Use this information: [source material]. Output: [format, length, tone]. Before answering, list any assumptions or missing information.

Saving tested templates for recurring tasks, such as briefs, ad copy or report summaries, makes AI output more consistent across a team.

Frequently asked questions

What is a prompt in AI?

A prompt is the input you give an AI model, such as a question or instruction, that tells it what to generate.

What is prompt engineering?

Prompt engineering is the skill of writing and structuring prompts, with clear tasks, context, examples and formats, to get accurate and useful AI output consistently.

How are AI prompts different from search keywords?

Prompts are usually longer and conversational, often include personal context, and expect a complete answer rather than a list of links.

What is a good prompt?

A good prompt gives the AI a clear task, relevant context, any examples or source material and the output format you want. Specific prompts produce more accurate and useful results than short, vague ones.
