Answer engine optimization (AEO) is the work of making your firm one of the names an AI tool gives when someone asks it a question. Where traditional search optimization targets a list of links, AEO targets the single written answer that tools like ChatGPT, Google's AI results, and Perplexity produce.
How is the term used?
"Answer engine" covers any tool that replies to a question with a direct written answer: ChatGPT, Google's AI answers above the normal results, Perplexity, Gemini, and voice assistants. AEO is the umbrella term for making your business visible inside those answers.
In practice, AEO work for a law firm means publishing pages that answer real client questions directly, adding structured data (machine-readable labels on your pages), keeping the firm's details identical across directories and profiles, and earning mentions on the sources answer engines cite.
Why it matters for law firms
Clients increasingly ask AI tools "who should I hire" and act on the handful of names in the answer. A firm can rank respectably in traditional search and still be absent from those answers. AEO is the discipline of closing that gap, and its results are measurable: ask the tools your clients' questions and record who gets named.
