What is answer engine optimization (AEO)? A practical guide for businesses.

You will see the same idea under several names. Wikipedia lists answer engine optimization as another term for generative engine optimization (GEO), alongside AI SEO and a few others, and its “Answer engine optimization” entry redirects to the generative engine optimization article. In practice, people use AEO for being the answer anywhere an engine replies directly: an AI summary, a featured snippet or a voice assistant.

For a business, the label matters less than the question underneath it: when someone asks about what you sell, does the answer include you, and is it right?

The broad pattern is similar everywhere: the engine finds candidate pages, picks the ones it will draw on, writes an answer and links some of its sources. The details are not. Each platform documents access in its own way, and none publishes exactly how it chooses which sources to cite.

The practical takeaway: access is documented and checkable, selection is not. So make sure each engine you care about can reach your pages, then make those pages the clearest, best-supported answer available.

For Google, the answer is refreshingly short. Its page on AI features and your website says there are no additional requirements or special optimizations for AI Overviews or AI Mode. A page needs to be indexed and eligible to show with a snippet. You do not need new machine-readable files, AI text files or special schema.org markup. The usual SEO fundamentals, such as crawlable pages, internal links, text content and structured data that matches the visible page, are what Google points to.

Headings that match the question

Write headings the way buyers ask: “How much does it cost to…” rather than “Pricing overview.” One question per section keeps each answer easy to lift out.

A direct answer, then the detail

Put the answer in the first sentence or two under the heading, in words that still make sense on their own. Then support it: the numbers, the conditions, the exceptions. Answer engines, voice assistants and skimming readers all reward the same structure. Our guide to voice search SEO covers the spoken version of this.

Structured data that matches the page

Schema markup helps machines read what a page is about, but Google says no special AI schema is needed and that structured data should match the visible text. Mark up what is on the page; do not mark up what is not.

The same facts about you everywhere

Your business name, what you sell, who you serve, where you work and your prices should read the same on your site, your Google Business Profile, directories and social profiles. When sources disagree, an answer engine has to choose, and it may choose wrong.

Mentions on sites people trust

Answer engines draw on the wider web, not only your site. Reviews, industry lists, partner pages, interviews and press all shape what gets said about you. Earn them; do not buy them.

Access for the engines you care about

• Check robots.txt for Googlebot, OAI-SearchBot and PerplexityBot, depending on where you want to appear.
• Check your firewall and bot protection too. Perplexity notes that sites using a web application firewall may need to allow its crawler explicitly.
• Keep training and search settings separate where platforms allow it. OpenAI and Perplexity both describe their search crawlers as independent of model training.

If you want help producing answer-ready pages at a steady pace, our content marketing team works that way.

Measurement is partly available and partly manual. Google includes AI features traffic in the Search Console Performance report, in the Web search type, with no separate AI report. OpenAI says ChatGPT adds utm_source=chatgpt.com to the links it sends, so those visits show up in analytics, according to its publishers and developers FAQ.

The rest is observation: a fixed set of buyer questions, checked on each platform on a schedule, with the date, the answer, whether you were mentioned, which pages were cited and whether the facts about you were right. Patterns across several checks are meaningful. A single answer is not.

Most of the work overlaps, which is good news: done well, the same page serves both. Our AI search optimization page explains how we approach the part that does not.
