What is Answer Engine Optimization (AEO)?

Answer Engine Optimization (AEO) is the practice of getting your brand recommended by AI assistants (ChatGPT, Claude, Gemini and Perplexity) when buyers ask them what to choose. Where SEO competes for a ranking in a list of links, AEO competes to be named inside the answer itself.

Why AEO matters now

Search behaviour has shifted faster than most marketing plans have. Around 900 million people now use ChatGPT every week (OpenAI, via TechCrunch, Feb 2026), and when Google shows an AI summary, people click through to a website on just 8% of visits, down from 15% without one (Pew Research Center, 2025). In B2B, 45% of buyers said they used AI tools during a recent purchase (Gartner, 2025).

The practical consequence is simple: when the answer comes back as three names and yours isn't one of them, you never enter the consideration set. The buyer acts on what the assistant said, and you never see the visit you lost.

AEO vs SEO, what actually changes

SEO optimised a page to rank in a list the user then chose from. AEO optimises content so a model extracts and repeats it as the recommendation. The shift, in plain terms:

  • Keywords become questions, the exact way a buyer phrases it to an assistant.
  • Rankings become mentions and citations, are you named, and is your page cited as a source?
  • A blue link becomes a named recommendation, the assistant does the choosing.

SEO doesn't disappear, the pages an AI reads are often the pages that already rank. But the goal moves from “be on the page” to “be in the answer.”

How answer engines decide who to recommend

Four levers do almost all the work, and you control every one of them on your own site:

  1. 1

    Authoritative content that answers the question

    The single biggest lever. Publish the page that directly answers the buyer's question, in the format the question implies, a “best X for Y” query wants a guide that names the field, not a brochure. Write it so a model can lift a clear, correct answer from it.

  2. 2

    Structured data the model can read

    Schema.org markup (Organization, FAQPage) states your facts in a machine-readable form. FAQPage here exists to be extracted by LLMs, it is not about winning a Google rich snippet. State real facts; never invent ratings.

  3. 3

    Clean crawlability

    A sitemap and a robots.txt that allows the AI crawlers, GPTBot, ClaudeBot, PerplexityBot, are the load-bearing pair. An llms.txt file is low-cost hygiene that points them at your priority pages. If the bots can't read you, none of the above counts.

  4. 4

    Owned profiles, kept complete

    Claim and complete the profiles you genuinely control, G2, Trustpilot, LinkedIn, Crunchbase, Wikidata. You can't buy your way into editorial coverage, but you can keep your own entries accurate so the model has good facts to draw on.

How fast does AEO work?

Honestly, it depends on the engine. Retrieval engines (Perplexity, and the web-search modes of ChatGPT and Gemini) pick up new pages within days of crawling them. A model's built-in training memory only shifts when it's retrained, so some wins are quick and some build over time. The right move is to publish, then re-check the answers on a cadence to watch the recommendation move.

How to start

  1. 1

    Find out where you stand

    Ask the engines the exact questions your buyers ask, and see who gets named. You can't fix a gap you haven't measured.

  2. 2

    Publish the answer you're losing

    For each question you're absent from, publish the page that answers it best, sized to your brand.

  3. 3

    Make it readable, then measure

    Add the schema, keep the page crawlable, then re-check the answers to confirm the recommendation moved.

Frequently asked questions

Is AEO the same as GEO?

Largely, yes. Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are used interchangeably for the same goal: being recommended inside AI-generated answers. Some people reserve GEO for generative chat engines and use AEO more broadly, but the work is the same.

Does AEO replace SEO?

No. They overlap, the pages an AI cites are often pages that also rank well in Google, but the goal differs. SEO competes for a link in a list; AEO competes to be the named recommendation inside the answer. Most brands do both.

Can I pay to be recommended by ChatGPT?

No. There is no ad slot inside the organic answer. You earn the recommendation with content the model trusts and can read, on a site its crawlers are allowed to reach.

How do I know if AI already recommends me?

Ask the engines the questions your buyers ask, and read the answers. MentionLM does exactly this across ChatGPT, Claude, Gemini and Perplexity in about ten seconds, then shows who gets named instead of you.
