What is answer engine optimization (AEO)?

Answer engine optimization (AEO), explained

An answer engine responds with an answer instead of a list of links: Google's featured snippets and "People also ask" boxes, voice assistants, and AI systems like ChatGPT, Perplexity and Google's AI Overviews. AEO is the work of becoming the page such a system quotes. You can't mark a page up as a featured snippet; Google says its systems decide whether a page would make a good one.

AEO and GEO overlap so much that many people use the terms interchangeably. If there's a difference, it's emphasis: AEO is about the answer itself (can a system lift a short, correct, self-contained reply from your page?), while GEO is about being retrieved, trusted and cited by generative systems, including how the rest of the web describes you. Google's own AI guide (May 2026) names both labels and calls optimizing for generative AI search "still SEO". Our guide to GEO covers the research behind the tactics.

The habits are cheap. Put the question in a heading, in the words people use. Answer it in the first one or two sentences below, so it still makes sense if quoted alone. Then add detail for readers who want more. Use real HTML lists for steps and tables for comparisons, and keep one idea per section. These are writing heuristics, not documented ranking factors: Google says you don't need to write in a specific way for its AI features, and that clear paragraphs, headings and text-based content help readers.

Markup isn't the strategy. FAQ rich results stopped appearing in Google Search on May 7, 2026, and HowTo rich results went in 2023. Google says its AI features need no special schema.org markup. Use structured data if it describes the page honestly, but don't expect it to get you quoted.

The trade-off is real: a quoted answer can satisfy the searcher without a click. In practice, AEO works best for questions where a short answer leads to a bigger need, like "what is llms.txt" leading to "generate one for my site". To see whether assistants name you, let our AI visibility checker ask four buyer questions about your site.

Why it matters for founders

Answer-first writing can make one page work for classic search, featured snippets and AI assistants. It costs only editing discipline, and readers who skim benefit too.

Example

Under the heading "Does llms.txt help Google rankings?", the first line reads "No. Google says Google Search ignores llms.txt files." That sentence is easy for a snippet or an assistant to quote, with a link back.

Common mistakes

• Long preambles before the actual answer.
• Answers that only make sense with the paragraph above them.
• Relying on FAQ or HowTo markup for visibility Google no longer gives it.
• Answering questions nobody asks. Check People also ask and your Search Console queries first.
• Creating a page for every possible phrasing of a question. Google says doing that mainly to manipulate rankings or AI responses is scaled content abuse.
