AEO in one line

SEO tries to win a place in a list of links. AEO tries to be the answer: your brand named in the text, and your page linked as the source.

How AI engines pick what to say

ChatGPT, Claude, Gemini, Perplexity and Google's AI features search the web while they answer, read a handful of pages and write from them. So AEO has two halves:

  1. Be readable. The engines' crawlers must be allowed in, by your robots.txt and by your CDN, and your content must be in the page's HTML without JavaScript.
  2. Be in the sources they read. Your own pages, and the third-party pages the engines keep citing for your category: GitHub lists, Reddit threads, roundup articles, directories, videos.

How to measure it

Pick the questions your buyers ask at each stage, from "how do I…" to "is X free", run them on each engine, and count two rates:

RateWhat it counts
Mention rateAnswers that name your brand
Citation rateAnswers that link a page on your site

Keep the questions fixed and re-run them every few weeks. Answers change from run to run, so compare rates, not single answers. Our own AI visibility baseline shows the method with real numbers.

Doing it with Manifold

Your agent can run any question on ChatGPT, Claude, Gemini, Perplexity, AI Overviews and AI Mode with aeo_run_ai_answers, at 27 credits a question on the five default engines, and see every brand named and every page cited. aeo_search_prompts shows questions people already ask the engines, and aeo_get_site_readiness checks for free whether the crawlers can read your site.

Where to go next

Questions people ask

Is AEO the same as GEO?

In practice, yes. Both name the work of showing up in AI-generated answers. GEO comes from a 2023 research paper; AEO is the term more marketers use.

How is AEO different from SEO?

SEO aims for a high position in a list of links. AEO aims for a mention or a citation inside the answer. The two overlap: AI engines search the web while they answer and often cite pages that already rank.

How do I measure AEO?

Pick the questions your buyers ask, run them on each AI engine, and count how often your brand is named and your site is cited. Re-run the same questions every few weeks and compare the rates.

What is the first AEO fix?

Make sure the AI crawlers can read your site: robots.txt and your CDN must let them in, and your key content must be in the HTML without JavaScript.
