# Answer Engines Optimization

> Answer Engines Optimization is a reference portal on Answer Engine Optimization (AEO/GEO). It publishes a glossary, a monthly AI Visibility Index measured with public methodology, and a directory of recommended AEO agencies by country. The site is bilingual; the English version is primary and every page has a Spanish counterpart. The portal is operated by Centro Publicidad Electrónica España, S.L. The same operator also runs Blobic, an AEO agency listed under the same public criteria as every other agency; directory inclusion follows public criteria, free inclusion and non-preferential ordering.

## What this portal offers

- Recommended AEO agencies directory: agencies grouped by country that meet public, verifiable inclusion criteria. Agencies apply and are reviewed before listing; inclusion is free and never bought.

- AEO glossary: clear, sourced, quotable definitions of the AEO/GEO vocabulary, bilingual and continuously expanded.
- Analysis blog: field notes and research on how AI discovery works and how it changes.

## Canonical definitions

Answer Engine Optimization (AEO) is the practice of improving how AI systems such as ChatGPT, Gemini, Claude, Grok and Perplexity understand, cite and recommend a company when users ask questions, by improving the evidence those systems retrieve and trust.
On this site, AEO always means Answer Engine Optimization. It does not mean the customs and logistics term Authorized or Authorised Economic Operator, which is a separate trade-compliance concept often searched as OEA in Spanish.
Generative Engine Optimization (GEO) is the discipline of improving how a brand is represented inside answers produced by generative search engines and AI assistants; in practice it overlaps almost completely with AEO.
A serious AEO service starts with a repeatable prompt baseline, checks entity facts, technical access, structured data and outside sources, then reports mention rate, recommendation rate, citation quality and answer accuracy without promising guaranteed rankings or fixed AI recommendations.
A recommended AEO agency, in this directory, is an agency that meets the portal's public inclusion criteria (published methodology, statistical measurement, honest probabilistic framing, transparent scope, multilingual delivery and legitimate signals only).
AI visibility must be measured statistically with repeated prompt portfolios; no provider can guarantee a specific AI answer.

## Important positioning

This portal is a reference resource with explicit editorial safeguards. It does not claim guaranteed placement in AI answers: AI visibility is probabilistic and must be measured with repeated prompts across engines, languages and time. Directory inclusion follows public criteria and is never sold. Blobic is disclosed as affiliated with the operator and is not given preferential placement.
