Answer engine optimisation (AEO): a practical guide

What is answer engine optimisation?

Answer engine optimisation is the practice of writing and structuring content so it can be used as the direct answer to a question. An answer engine is anything that returns an answer rather than a list of links: the featured snippet at the top of Google, the People Also Ask box, a voice assistant reading a reply aloud, or an AI tool writing a response.

AEO is more granular than SEO. SEO works page by page to earn a ranking. AEO works question by question, on the wording and structure of individual passages, so that one paragraph or list on your page becomes the one that gets picked.

It also overlaps with GEO. GEO is about whether AI assistants mention your brand at all. AEO is about whether your specific answer is the one they use. The same answer-first writing helps with both.

How do answer engines pick an answer?

Each surface works slightly differently, and none of them publish the full rules. What they share is a preference for passages that answer the question directly, match the way it was asked, and come from a page that already ranks reasonably well for that query.

Featured snippets and People Also Ask are usually drawn from pages on the first page of results. Voice assistants often read out a featured snippet or a short passage from a high-ranking page, so they favour answers that make sense spoken aloud. AI answers retrieve several pages and combine them, which rewards clear, self-contained statements that agree with other good sources.

• Featured snippets: one passage, list or table shown above the results.
• People Also Ask: related questions that expand into short answers, each linking to a source.
• Voice assistants: a single spoken answer, usually short.
• AI answers: a written response built from several retrieved pages, sometimes with citations.

How do you find the questions your buyers ask?

Start with the questions people already bring to you, then check which of them have search demand. Guessing is the most common mistake. Teams write answers to questions they find interesting rather than the ones buyers type or say.

Collect from several sources, group the questions by intent, and keep the ones with either real search demand or real sales value. A question that comes up on every sales call is worth answering even if search tools show little volume for it.

• Search Console: filter queries for question words such as what, how, why, can, does and which.
• People Also Ask: search your main topics and note the questions Google expands, and the ones that appear when you open them.
• Sales call notes and transcripts: the questions prospects ask before they buy.
• Support tickets and chat logs: the questions customers ask after they buy.
• Reviews and forums: the words buyers use when they describe the problem.

How do you write an answer-first page?

Put the question in a heading, phrased the way people ask it. Then answer it in the first sentence underneath, plainly and completely enough to stand on its own. Only after that add the context, conditions, examples and detail.

A useful test is to read the first sentence out of context. If someone heard only that sentence, would they have the answer? If it starts with background, a story or a sales line, rewrite it so the answer comes first.

Keep the direct answer short, usually one or two sentences. Use the key term from the question in the answer, define it if needed, and avoid hedging that hides the point. The detail that follows is where you show depth and earn trust.

Which content formats get chosen as answers?

Match the format to the question. A "what is" question wants a definition. A "how do I" question wants numbered steps. A "which is better" or "how does X compare" question wants a table. A "what are the options" question wants a short list.

Use real HTML structure for these formats: proper heading tags, ordered and unordered lists, and table elements rather than images of tables. Machines read the structure, not the visual layout.

• Definitions: one sentence that names the term and says what it is, then a sentence on why it matters.
• Numbered steps: one clear action per step, in the order someone would do them.
• Tables: side by side facts for comparisons, with clear column headings.
• Short lists: options, types or factors, each item a few words to one sentence.

How do you do FAQ pages and FAQPage schema properly?

Answer each question once, in the one place it belongs, and link to that answer from elsewhere. A thin FAQ block repeated across ten pages splits attention and gives answer engines no clear source. A question about pricing belongs near pricing; a question about setup belongs on the setup page.

Write FAQ answers the same way as any other answer: direct first sentence, then detail. Keep them current. An FAQ that still describes last year's process does more harm than having no FAQ.

FAQPage schema marks up which text is the question and which is the answer. Google shows FAQ rich results for very few sites now, so do not add it expecting extra space in the results. It still helps machines parse the page, as long as the marked-up text matches what is visible.

How do you measure AEO?

Pick a set of target questions and check them on a regular schedule. For each one, record whether a featured snippet or People Also Ask entry appears, whose site holds it, and whether AI answers for the same question use your wording or cite your page.

Pair that with Search Console data for the same queries: impressions, clicks and average position. A snippet you win should show up as more impressions and often a change in clicks. Track monthly, adjust answers that are not being picked up, and add new questions as sales and support surface them. WhiteThread runs this tracking as part of its AEO work, but a simple spreadsheet is enough to start.
