New abbreviations are appearing rapidly in the field of visibility, and AEO is the most confusing of the bunch. Not because the concept is complicated, but because the abbreviation was already taken in the Netherlands before the marketing world started using it.

01 / the confusionTwo meanings of the same abbreviation

Let's clear up the confusion first. In the Netherlands, AEO has for years been the abbreviation for Authorised Economic Operator: a customs status with a certificate and a licence, for companies trading internationally. According to our keyword analysis from August 2026 (DataForSEO), "aeo" is searched around 1,300 times a month in the Netherlands, and those searchers mostly mean the customs status: the search results are led by Customs itself.

The marketing term is younger and smaller. "Answer engine optimization" is searched around 140 times a month and "what is aeo" around 90 times, with mixed intent. If you're looking for information about the customs certificate, you're in the wrong place here and are best off going to Customs. If visibility in AI answers is what interests you, read on.

02 / definitionWhat AEO means in marketing

An answer engine is any system that returns not a list of links but an answer: the AI block above Google's search results, and assistants such as ChatGPT, Perplexity and Claude. Such a system assembles its answer from passages it can read and cite. AEO is the discipline of getting your page to supply that passage.

In practice, AEO focuses on a handful of recognisable measures: your customer's question verbatim in the heading, the complete answer right in the first paragraph, passages that are readable on their own without the rest of the page, and a frequently asked questions block with real questions and complete answers. What AEO is not: a trick or a shortcut. An answer engine copies what is readable and credible, and that starts with content that genuinely answers the question. What that adds up to across all platforms together, we describe in what AI visibility is.

03 / the listAEO alongside GEO alongside SEO

The three abbreviations largely describe the same work from a different angle:

AEO and GEO overlap so strongly that in practice you can treat them as synonyms; the difference lies mainly in who uses the term. Both build on the foundation of SEO: a site that isn't technically readable ends up in no answer at all. Exactly how that relationship works is set out in what GEO is and how it differs from SEO.

AEO, GEO and AI-SEO are three names for the same discipline: making sure the machine's answer is your answer.

04 / the evidenceDoes it work, and how do you know

The effect of this kind of measure has been measured. Princeton's GEO study (KDD 2024) compared optimisation methods and found that citing sources increases visibility in AI answers by around 40 per cent, adding statistics by 37 per cent, and quoting experts by 30 per cent. The same study measured that stacking keywords actually decreases visibility by around 10 per cent. Solid answers, then, demonstrably beat tricks.

For your own site, a study from the literature proves nothing yet. Only measurement does that: recording in advance which search queries you want to be visible for, establishing where you stand now, and re-measuring monthly with the same method. The setup of that yardstick is worked out in how you measure AI visibility.

05 / the limitWhen AEO isn't your priority

If your customers don't come in through online searching or comparing, an answer engine changes little about your inflow, and you can safely leave this topic alone. The same applies as long as your site doesn't yet answer your customers' basic questions: an answer engine can't copy something that isn't there. Start with those pages instead, and come back to this afterwards.
