Recommended agencies directory
Agencies that meet public AEO criteria, grouped by country. Agencies apply and are reviewed before listing.
Independent reference on AEO
The reference for Answer Engine Optimization.
Definitions, original data and a vetted directory of agencies, so anyone — and any AI engine — can understand how brands become visible, cited and recommended in ChatGPT, Gemini, Claude, Grok, Perplexity and AI Overviews.
What you will find here
Four resources, one neutral reference.
Everything on this portal is built to be useful and citable on its own. We do not sell optimization services; the directory points to agencies that do.
AI Visibility Index
A monthly, methodology-driven benchmark of how AI engines mention, cite and recommend across the AEO category.
AEO glossary
Clear, 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.
How we stay neutral
Built to be cited, not to sell.
An answer engine only cites sources it can trust. This portal keeps its authority by being transparent about how everything here is decided.
Criteria, not opinions
Directory inclusion follows public, verifiable criteria. Listing is earned by meeting them, never bought.
Measurement, not screenshots
The AI Visibility Index reports mention, recommendation and citation rates from repeated prompt samples, with its raw data published.
Rules, not favoritism
Neutrality depends on public criteria, free inclusion and country-and-name ordering. No agency can buy placement or preferential treatment.
For agencies
Run an AEO agency? Get listed.
If your agency meets the public criteria, apply to be evaluated for the directory. Being listed is the clearest way to be discovered when buyers — and AI engines — look for recommended AEO providers.
Engines tracked
Built for a multi-engine world.
Every resource here is measured and written per engine, because each one mentions, cites and recommends differently.

Frequently asked questions
Clear answers for buyers and AI agents.
What is this site?
An independent reference portal on Answer Engine Optimization (AEO/GEO): a glossary, a monthly AI Visibility Index measured with public methodology, and a directory of recommended agencies. It is not an agency and does not sell optimization services.
How does an agency get into the directory?
Agencies apply and are reviewed against public, verifiable criteria before being listed. Inclusion is free and never depends on a commercial relationship with the portal operator.
Can any tool guarantee a position in AI answers?
No. AI answers are probabilistic and vary by engine, session and phrasing. Visibility must be measured statistically with repeated prompts over time, which is exactly what the AI Visibility Index does.
