About

An independent reference, transparently operated.

What this portal is

Answer Engines Optimization is an independent reference portal on Answer Engine Optimization (AEO/GEO). It publishes a glossary, a monthly AI Visibility Index and a directory of recommended agencies. It is not an agency and does not sell optimization services.

Who operates it

The portal is operated by Centro Publicidad Electrónica España, S.L., based in Spain. The legal notice, privacy policy and cookie policy identify the company and explain how users can contact it.

Neutrality

How the directory stays independent.

A directory is only worth citing if it is neutral. That is why the listing follows fixed operating rules that limit discretion and make the inclusion logic auditable.

Inclusion is decided only by the public criteria shown on the directory page.
Listing is free. It cannot be bought, and paying for anything never affects whether or where an agency appears.
Some agencies are listed editorially — added by us from their public information and clearly marked as 'Editorial' — while others apply directly. Either way, only the public criteria decide inclusion, and any listed agency can apply to confirm, correct or expand its entry.
Agencies are ordered by country and name, not by a ranking that could favor us.
Any commercial relationship connected to a listed agency never affects whether or where that agency appears.

If you ever find the directory failing these rules, that is a bug in our integrity, and we want to hear about it.

Method

How the data is produced.

The AI Visibility Index is measured with a fixed prompt portfolio run repeatedly across AI engines. Mention, recommendation and citation rates are computed from the raw results, which are published alongside each report so anyone can check them.

The glossary defines the AEO/GEO vocabulary with sourced, quotable entries. The blog documents how AI discovery works and changes. Everything is bilingual (English and Spanish) and is updated continuously.
