**Answer engine optimization is the work of making a page easy for an assistant to read, quote and cite. This guide covers how ChatGPT, Claude, Perplexity and AI Overviews build an answer, what they quote, how to structure pages and files for them, and a 20-point checklist you can run this week.**

A buyer used to open Google, scan ten blue links and pick two. Today a growing share of them type the same question into ChatGPT, Claude or Perplexity and read one answer with three or four sources attached. If your page is not in those sources, you are not in the shortlist, no matter how well you rank on the classic results page.

Answer engine optimization, or AEO, is the work that gets you into those answers. It is not a new marketing channel and not a rebrand of SEO. It is a set of technical and editorial decisions that make a page easy for a model to retrieve, easy to read without a browser, and safe to quote with a link back to you.

This guide is written from our own practice: we rebuilt [figmatica.com](https://figmatica.com/) around these rules first and then started doing it for clients. Everything below is something you can check on your site today.

> **Key takeaway:** SEO gets you into the list of results. AEO gets you into the answer itself.

## What answer engine optimization actually is

Answer engine optimization is the practice of preparing content, markup and site files so that an AI assistant can find your page, understand what it says, and reuse a passage from it in its answer with a citation. The unit of success is not a position in a list. It is a sentence of yours appearing inside someone else's answer, with your domain named next to it.

That changes what a good page looks like. A model does not scroll, does not hover and does not wait for a carousel. It reads text, headings, lists and structured data. It rewards pages that answer a question in the first two sentences of a section and punishes pages that bury the answer under three paragraphs of warm-up.

- **It is technical.** Crawler access, clean HTML, structured data, machine-readable copies of key pages.
- **It is editorial.** Question-shaped headings, direct first sentences, numbers with a date and a source.
- **It is about entities.** Who you are, what you do, which named people stand behind the text, and where else that is confirmed.

## AEO, GEO and SEO: the words people mix up

Three terms circle the same idea. SEO is optimization for a results page: ranking, clicks, dwell time. AEO is optimization for an answer: retrieval, quotability, citation. GEO, generative engine optimization, is the same work described from the engine side, and in practice the two terms are used interchangeably by most teams.

The practical difference is what you optimise against. In SEO you fight for a slot among ten links. In AEO you fight to be the passage a model trusts enough to paste into a two-hundred-word answer. The first rewards breadth, the second rewards precision and verifiability.

You do not choose between them. A page that an assistant quotes is almost always a page that ranks, because both systems read the same signals: clear structure, real expertise, working links. AEO adds a machine-facing layer on top of the SEO you already have. We describe how the two fit together in our [SEO and AEO approach](https://figmatica.com/services/seo-aeo-approach).

## How an assistant builds an answer

Knowing the pipeline tells you where to intervene. Every assistant that cites sources goes through four steps, and each one has a failure mode you can fix.

- **1. Query fan-out.** The model rewrites your question into several search queries. If your page only matches the exact phrase a human would type, it misses the rewrites.
- **2. Retrieval.** It pulls candidate pages from a search index or its own crawl. Blocked crawlers, JavaScript-only content and slow pages drop out here.
- **3. Reading and ranking.** The model reads the text it received and picks passages that answer the question directly. Long intros and vague claims lose to a crisp paragraph.
- **4. Synthesis and citation.** It writes one answer and attaches sources. Pages it could verify get named; pages it half-understood get paraphrased without a link.

## Why classic SEO wins do not transfer

Plenty of pages that rank well are quoted rarely. The usual reasons are mechanical. The answer lives in an accordion that never opens for a crawler. The key number sits inside an image. The page is one long argument with no section that stands on its own. The claim has no date, so the model cannot tell whether it is still true.

There is also a volume trap. Long pages built for keyword coverage give a model hundreds of near-identical sentences and no obvious passage to lift. A shorter page with eight clean sections often wins the citation, because every section is a self-contained answer.

> **Key takeaway:** If a section cannot be copied out and still make sense, a model will not copy it out.

## What assistants quote: seven traits of a citable page

- **A direct first sentence.** The section opens with the answer, then explains. Not «in today's fast-moving landscape».
- **Question-shaped headings.** Headings that match how people ask give the model an anchor to retrieve and to cite.
- **Numbers with provenance.** A figure with a date and a source is quotable. A figure without them is a risk the model avoids.
- **A named author.** Models prefer text attached to a person with a profile, a role and a track record.
- **Clean HTML.** Text in the markup, not painted by scripts after load, and not locked behind a cookie wall.
- **Structured data that matches the page.** Article, FAQPage, Organization and Person markup that repeats what a human reads, never more.
- **A visible update date.** Freshness decides ties. Show when the page was last changed and change it when facts change.

## Structure a page so a model can lift the answer

Write every section as if it will be read alone, because that is what happens. One question, one section, one answer in the first two sentences. Then the detail, the caveat and the example. Keep sections between 120 and 250 words: long enough to be useful, short enough to be quoted whole.

Use lists for anything countable: steps, criteria, options, mistakes. Lists survive the trip into an answer better than prose, and assistants often reproduce them verbatim. Put the summary before the table, not after it, because a model that stops reading early still gets the point.

One more habit: repeat the entity. Say «Figmatica» instead of «we» at least once per section on pages where the subject matters. It reads slightly formal to a human and removes all ambiguity for a model deciding who the answer is about.

## The machine-readable layer: llms.txt, Markdown twins, schema

Alongside the pages people read, publish a version made for machines. Three files carry most of the weight, and all three are cheap to produce once your content is structured. The same layer is the first floor of an [agentic website](https://figmatica.com/blog/what-is-an-agentic-website), a site AI agents can read and act on.

- **llms.txt.** A single Markdown file at the root with what you do, who for, your main pages and a few quotable facts. Think of it as a press kit for models. Ours lives at [figmatica.com/llms.txt](https://figmatica.com/llms.txt). What the file can and cannot do, with the evidence: [what is llms.txt](https://figmatica.com/blog/what-is-llms-txt).
- **Markdown twins.** Every important page also served as plain Markdown at the same address with a .md suffix, so a model gets the text with no navigation, banners or scripts.
- **Structured data.** Organization and Person for who you are, Article for posts, FAQPage for questions, Service for offers. Keep it in sync with the visible page or it becomes a liability.

## Crawler access: let the right bots in

None of the work above matters if the fetchers cannot reach you. Assistants use separate user agents for training, for search indexing and for live fetches when a user asks a question. Blocking all of them to protect content also removes you from answers.

Decide per bot, not in bulk. A reasonable default for most sites: allow the search and live-fetch agents, decide separately about training. Then check your server logs to confirm they actually arrive, because a rule in robots.txt and a CDN rule are two different things.

- **OpenAI.** GPTBot for training, OAI-SearchBot for search, ChatGPT-User for live fetches.
- **Anthropic.** ClaudeBot for crawling and Claude-User for fetches made during a conversation.
- **Perplexity.** PerplexityBot for the index and Perplexity-User when someone asks a question right now.
- **Google.** Googlebot still feeds AI Overviews, and Google-Extended controls Gemini training separately.

## Entity signals: make it obvious who you are

Assistants answer questions about entities: companies, people, products, places. Before a model recommends you, it needs to be confident that the entity exists, does what the page claims, and is the same one mentioned elsewhere. That confidence comes from repetition across independent sources.

In practice: one canonical about page, one consistent name and description, author pages for the people who write, and the same facts on your profiles, in your directory listings and in your reviews. Contradictions cost you more than gaps, because a model that sees two different claims usually cites neither.

## How to measure AEO without fooling yourself

There is no rank tracker for answers, and anyone selling you a precise «AI ranking» is selling a guess. What you can do is build a repeatable test: a fixed list of twenty questions your buyers actually ask, run in each assistant, logged with date, answer text and cited sources.

Then watch three numbers over time: how often you are mentioned at all, how often you are cited with a link, and where you sit among the named competitors. Support that with server-side evidence: referral traffic from assistant domains and hits from their user agents in your logs.

Set the cadence to monthly. Answers vary between runs, so a single check proves nothing; a trend across three months does. If you want the baseline done for you, that is exactly what our [AI visibility audit](https://figmatica.com/services/ai-visibility-audit) produces.

## The 20-point AEO checklist

Run this against any page you want quoted. Most teams can close two thirds of it in a week without a redesign.

- Every section answers one question in its first two sentences.
- Headings are phrased the way buyers ask, not the way you name things internally.
- Key facts sit in text, never only in an image or a video.
- Numbers carry a date and a source.
- The page names a real author with a profile page.
- A visible «updated» date matches the last real content change.
- Content renders in HTML without JavaScript.
- No cookie or consent wall blocks the text.
- Article, FAQPage, Organization and Person markup match the visible page.
- One canonical URL per topic, no duplicate near-identical pages.
- Internal links use descriptive text, not «read more».
- Outbound links point to primary sources for every borrowed claim.
- robots.txt names the assistant agents explicitly and allows the ones you want.
- The CDN or firewall does not silently block those same agents.
- llms.txt exists, is current, and links to your main pages.
- Markdown copies are served for key pages.
- The sitemap is complete and lastmod is honest.
- Page loads fast enough for a fetcher on a normal connection.
- Each language version is self-contained with correct hreflang.
- Twenty buyer questions are logged monthly across ChatGPT, Claude and Perplexity.

## What we changed on our own site

We treated figmatica.com as the first client. Every page got a Markdown twin, the site got an llms.txt with positioning, services, cases and quotable facts, and every article got a named author with a profile page and consistent Person markup. Robots rules name each assistant agent explicitly instead of a blanket allow.

The editorial half mattered as much. We rewrote section openings so the answer comes first, replaced vague claims with dated numbers, and split long pages into sections that stand alone. None of it required a redesign, and all of it made the pages easier for humans too.

> **Key takeaway:** Do it on your own site first. It is the only portfolio piece an assistant can verify.

## Mistakes that get you dropped from answers

- **Writing for the model, not the reader.** Keyword-stuffed paragraphs and hidden text for bots are the fastest way to lose trust in both systems.
- **Markup that promises more than the page shows.** FAQ schema with questions nobody can see on the page is a mismatch models and search engines both catch.
- **Undated claims.** «Recently» and «currently» age badly. Write the year, or the model will prefer a source that did.
- **Blocking every bot by default.** A blanket disallow protects nothing that a browser cannot already read, and it removes you from the shortlist.
- **One giant page per topic cluster.** Five focused pages that each answer one question beat a ten-thousand-word monolith almost every time.

## Where to start this week

Pick the five pages that would win you work if an assistant recommended them. Fix the first two sentences of every section, add dates to every number, publish an llms.txt, and open your robots rules to the search and live-fetch agents. That is a day of work and it covers most of the gap.

Then log your twenty questions and repeat the check in a month. If you would rather start from a map of the questions worth owning, that is what our [keyword and AEO discovery](https://figmatica.com/services/keyword-aeo-discovery) does, and the [AEO strategy](https://figmatica.com/services/aeo-strategy) service turns it into a publishing plan.

## Frequently asked questions

### What is answer engine optimization in simple terms?

It is preparing your site so an AI assistant can find a page, understand it and quote it with a link. Practically that means direct answers at the top of each section, clean HTML, structured data, a machine-readable copy of key pages and crawler access for assistant bots.

### Is AEO different from GEO?

In practice the terms describe the same work. AEO names it from the answer side, GEO from the generative engine side. Both mean getting your content into AI answers rather than only into a list of links.

### Does AEO replace SEO?

No. Assistants lean on search indexes, so ranking still helps you get retrieved. AEO adds a layer on top: passages that can be lifted, facts that can be verified and files that machines can read.

### How long does it take to see results?

Technical changes such as robots access and structured data can show up in answers within weeks, because assistants fetch live pages. Content work compounds over months, in step with your normal search growth.

### Do I need llms.txt if I already have a sitemap?

They do different jobs. A sitemap lists URLs for crawlers. llms.txt explains in plain language what you do, who you serve and which pages matter, so a model gets your positioning without parsing the whole site.

### How do I check whether ChatGPT cites my site?

Ask a fixed list of buyer questions in each assistant, record the answer text and the cited sources, and repeat monthly. Add server-side evidence: referrals from assistant domains and hits from GPTBot, ClaudeBot and PerplexityBot in your logs.
