What is answer engine optimization (AEO) for a startup — a plain guide

Search is changing under your feet. More people ask an AI a question and take its answer than scroll ten blue links. For a startup that means a new discipline sitting next to SEO: answer engine optimization (AEO) — making your company the answer that ChatGPT, Perplexity, Claude and Google’s AI Overviews actually give.

This is a plain guide. We run it on ourselves, so this doubles as a worked example.

SEO, AEO, GEO, AIO — how they differ

They stack; they are not synonyms.

• SEO — get indexed and ranked in traditional search results.
• AEO — be the answer: structure your content so an engine can lift a clean, correct answer straight from it.
• GEO (generative engine optimization) — get cited by generative chatbots when they compose an answer.
• AIO — show up in Google’s AI Overview, the box above the links.

A startup that only does SEO is optimising for the shrinking half of the funnel. AEO/GEO is the growing half.

Why startups should care now

The companies that get cited in AI answers early compound an advantage: every answer that names you is a recommendation you didn’t pay for. And because most startups do nothing here yet, the barrier is low. This is one of the rare windows where being small and moving early beats being big and slow.

How to start — the practical checklist

1. Publish machine-readable facts about your company. A consistent entity description everywhere, structured data (JSON-LD: Organization, FAQPage, Article), and an llms.txt file that tells AI crawlers what you are and where the good content is.
2. Write answer-first content. Lead with the answer, then explain. Use real questions as headings — the exact phrasing your customer would type. Engines match questions to answers; give them the match.
3. Be an entity, not just a website. Get listed on independent sources — a Wikidata entry, directories, profiles. Answer engines trust corroboration from places you don’t own. (Your own blog is necessary but not sufficient: it can’t vouch for itself.)
4. Keep it fresh and cite your sources. Recency and verifiable claims both raise the odds of being cited. Show your working.
5. Measure Share of AI Voice (SoAV). Pick the questions your customers ask, run them through each engine monthly, and record whether you’re cited. What you can’t measure, you can’t improve.

The honest part

AEO is not a switch you flip. It compounds over weeks as engines re-index and as independent sources accumulate. When we measured our own Share of AI Voice on our target questions, we started at zero — and we say so, because pretending otherwise would fail our own Truth-over-Performance rule. The point of measuring is to move the number, not to flatter it.
