What is Answer Engine Optimization, and is it worth paying for?

Why does AEO matter now?

Search behaviour changed faster than the agency industry did. People increasingly ask an assistant for a recommendation instead of scrolling a results page, and the assistant answers with a handful of named businesses. If you are not one of them, the visit never happens — there is no page two to be on.

Two honest caveats, because you will see wilder numbers quoted. The often-repeated claim that AI traffic converts 4× to 23× better than organic comes from single-company funnels; the only multi-site study that screened its sample and controlled for outliers found a median of 1.26×. And AI is still only 0.2–3% of sessions. It is growing fast and it converts somewhat better — it is not yet a flood.

The last two rows of the table are the real commercial story. Three times as many people say this matters as have any way of knowing whether it is working for them.

How is AEO different from SEO and GEO?

They are three names for overlapping work, aimed at different outcomes. SEO earns a position in a list of links. AEO and GEO (generative engine optimization, the term used in the 2024 academic research) earn a mention inside an answer. In practice AEO and GEO are the same job; the difference from SEO is what you measure.

The research behind the GEO name tested which edits make a page more visible in generative answers. Adding statistics, quotations and cited sources raised visibility by up to 40%, while keyword stuffing did not help. It was a lab study on 2023–24 engines, so read it as direction rather than a guaranteed number.

What makes an AI assistant cite a business?

AEO overlaps with SEO but is not the same job. Ranking is about being the best result for a query; being cited is about being the most quotable source for an answer. In practice that means:

• Schema markup on every page — the single clearest technical signal, and pages that carry it are 78% more likely to be cited
• Question-shaped headings with the answer in the first two or three sentences, because that passage is what gets extracted
• Concrete numbers, tables and dates rather than adjectives — assistants quote specifics and skip marketing language
• Third-party mentions, which drive citations 6.5× more than your own site does; listicles, directories and LinkedIn matter more than another blog post
• An llms.txt file pointing assistants at your most useful pages
• Crawler access actually allowed — a surprising number of sites block GPTBot by default and never notice

That third-party figure is the one most agencies get wrong. If someone proposes an AEO programme consisting entirely of on-site work, they have misread where citations come from.

What does a measured AEO result look like?

A count with its denominator, taken with web search switched on. These are two sites we build and run, checked against the questions their buyers actually type:

The gap between the two is the point. A local service with a clear answer to a narrow question gets named most of the time; a consumer brand in a crowded category gets named some of the time. Anyone who promises a citation rate before measuring your starting point is guessing.

How do you start AEO in two weeks?

• Day 1: check robots.txt allows OAI-SearchBot, GPTBot, PerplexityBot and Bingbot — many sites block them without knowing
• Day 2: write down the 20 questions your buyers ask before choosing someone like you, in their words
• Day 3: ask ChatGPT and Perplexity each question with web search on, and record who gets named — that is your baseline
• Days 4–8: rewrite your five most important pages so each opens with a two- or three-sentence answer to one of those questions
• Days 4–8: add Organization, FAQ and Service or LocalBusiness schema, and validate it
• Days 9–12: get listed where assistants look — industry directories, review sites, a LinkedIn company page
• Day 14: confirm in Search Console that the rewritten pages are indexed, then re-run the 20 questions monthly

How much does AEO cost?

There is no established price anchor at the small-business end yet, which is exactly why quoted prices vary by an order of magnitude for work described in identical language.

How can you tell whether an agency can really do AEO?

Ask one question: "Can you show me, today, whether ChatGPT currently mentions my business — and can you show me that again next month?" It is a hard question to bluff. Measuring it means repeatedly querying the assistants, recording what came back, and tracking the change over time.

• If the answer is a slide about "AI-first content strategy", they are selling SEO with a new label
• If the answer is a screenshot of one lucky query, they have no measurement, just an anecdote
• If they can hand you the tracked queries and the history, they have built something

Is AEO worth paying for?

Honestly: for some businesses, not yet. If almost nobody asks an assistant for what you sell, spend the money elsewhere and revisit in a year. AEO earns its place when your buyers research before choosing — professional services, considered purchases, anything where someone asks "who's good at X near me" before picking up the phone.

What is not defensible in 2026 is paying for visibility work that nobody measures. That was tolerable when the only channel was Google and rankings were at least checkable. It is not tolerable now that a growing share of demand is decided inside a conversation you cannot see.
