AEO meaning

AEO here means Answer Engine Optimization.

The acronym is ambiguous across industries, so this portal states its scope explicitly for readers, search engines and AI agents.

Answer Engine Optimization

In digital visibility, AEO is the practice of making a source easier for answer engines to understand, verify, cite and recommend when users ask direct questions.

Not customs AEO

AEO can also refer to Authorised Economic Operator in customs and logistics. That is a separate trade authorisation topic; this site covers Answer Engine Optimization for AI search and answer engines.

If you searched for AEO

Choose the right path for your intent.

AEO can mean learning the concept, measuring AI visibility, or finding an agency. This site separates those needs so the answer is more useful and verifiable.

I want to understand AEO

Start with the definition of Answer Engine Optimization, how it differs from SEO and GEO, and its limits: no rankings or recommendations can be guaranteed.

I want to measure AI visibility

Use our guides and tool profiles to compare mentions, citations, recommendations and sampling methods. The public index is paused.

I want to evaluate agencies

Review the directory and public criteria before talking to providers, without paid placements or artificial promises.

What you will find here

Four resources, one criteria-based 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.

Agency directory

Agencies that meet public AEO criteria, grouped by country. Agencies apply and are reviewed before listing.

Tools catalogue

Documentary profiles of AI visibility software and hybrid services, with sources, coverage and limitations.

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 limit bias

Built to be cited, not to sell.

An answer engine only cites sources it can trust. This portal keeps its authority by making its criteria, operator and directory disclosures visible.

Criteria, not opinions

Directory inclusion follows public, verifiable criteria. Listing is earned by meeting them, never bought.

Measurement, not screenshots

Our guides distinguish mentions, recommendations and citations, and ask for dated, comparable observations. The paused public index is not a current source of measured results.

Disclosure, not favoritism

The operator-affiliated Blobic listing is marked as such. No agency can buy placement or preferential treatment; ordering is by country and name.

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?

A bilingual reference portal with agency profiles, tool research, guides, glossary and blog. The public AI Visibility Index is paused. The operator also operates Blobic; directory inclusion is not an independent endorsement.

What does AEO mean on this site?

On this site, AEO means Answer Engine Optimization: the discipline of making a brand, product or expert source easier for answer engines and AI assistants to understand, cite and recommend. It is different from the customs acronym AEO, which can mean Authorised Economic Operator.

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; operator-affiliated entries are disclosed.

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, rather than inferred from a single screenshot. Our public index is paused.
