Prompt Engineering for LLMs

What is prompt engineering?

Prompt engineering is the practice of designing the text you send to a large language model (LLM) so it returns the output you actually want. It spans the wording of a single question, the examples you include, the role and constraints you set, and how you chain several calls together.

Because LLMs respond to patterns in their input, small changes — an explicit format, a worked example, a clear constraint — often move quality more than a bigger model would.

Common techniques

• Instruction clarity — state the task, the audience, and the output format explicitly instead of hoping the model infers them.
• Few-shot examples — show one or two examples of the input→output you want; the model matches the pattern.
• Role and context — tell the model who it is and what it knows ("You are a GTM analyst…") to steer tone and depth.
• Constraints — bound length, format, and what it must not do; ambiguity is where models drift.
• Chaining — break a hard task into steps (draft → critique → revise) rather than asking for everything at once.

Why it matters for marketing

LLMs are now a discovery surface. Buyers ask ChatGPT and Claude "what tool does X?" and the model answers from what it has read. Understanding how prompts surface and cite sources is the foundation of AI search visibility — the emerging discipline of earning a mention when a model, not a search engine, is doing the recommending.
