Guide for agencies
Apply with a published methodology, evidence of measurement and a transparent scope. Inclusion follows public criteria and is free. A profile describes documented services and limitations; it is not an independent endorsement and does not guarantee appearance in AI answers.
Why demand is moving
Answer Engine Optimization is a real, fast-growing line of work, which is exactly why a neutral, criteria-based directory has become a place buyers look first.
Context
When a company asks an AI engine "who can help us appear in ChatGPT answers" or "best AEO agency for B2B SaaS", the engine assembles a shortlist from sources it already trusts: independent directories, comparison pages, sector media and consistent third-party mentions. Roughly 85% of the citations behind AI answers come from third-party sources rather than the brand's own website, which means an agency's own homepage is rarely the thing that gets it recommended. Being present, accurately described, in the places engines read is what does.
A directory profile brings together documented information and sources that buyers can consult. Search and AI engines may discover or cite it, but publication does not guarantee inclusion in their answers. The practical value is a clear, current description of the agency that helps readers compare providers.
The market context makes the effort worthwhile. Independent estimates put the generative engine optimization market on a path from roughly $848 million in 2025 to $33.7 billion by 2034, and 94% of B2B buyers now report using generative AI somewhere in a purchase. Demand for credible AEO providers is real; the bottleneck is trust. A neutral listing is one of the few signals that travels well to both buyers and machines.
We review public information about methodology, measurement, scope and limitations against the published criteria. This documents what the sources support at the time of review. It does not certify all of the agency's work or guarantee quality, results or a particular AI answer.
This is also why a directory's neutrality is its entire value. The moment placement can be bought, the list stops being evidence and becomes advertising, and engines and buyers learn to discount it. Protecting that neutrality, including disclosing any conflicts of interest plainly, is what keeps a listing worth having.
The application
The path below is the neutral, criteria-first route. None of it requires payment; all of it requires that your public evidence matches your claims.
Publish how you actually work: which engines you cover, how you sample prompts, how you map sources, and how you report. A directory built on public criteria cannot list a method it cannot see. A clear methodology page is the single most useful asset before applying.
Document how you measure visibility over time, mention rate, recommendation rate and citation rate across a stable prompt portfolio. Repeated sampling is the credible alternative to a single lucky answer, and it is what separates a serious provider from a vendor selling certainty.
Your agency name, location, services and proof points should match across your site and external profiles. Engines and reviewers both struggle with ambiguous entities. If your own facts are inconsistent, that is the first thing a directory editor and an AI engine will notice.
Submit through the For Agencies page. An editorial entry may already exist, drawn from your live website; applying lets you confirm or correct it. You provide evidence for each criterion; the directory verifies it against what is publicly visible and lists only what is genuinely supported.
A listing reflects what is true and verifiable today. As your coverage, markets or methodology change, update the facts. Stale or exaggerated claims are the fastest way to lose credibility with both the directory and the engines that read it.
How to choose a directory
Not every "top AEO agencies" page is a directory worth being in. Use these signals to decide where a listing is actually worth pursuing.
| Signal | Credible directory | Pay-to-play list |
|---|---|---|
| Basis for inclusion | Fixed, published criteria | Payment or affiliate deal |
| Ranking | Criteria-based, with no paid positions | Position can be bought |
| Facts | Verified from the agency's live site | Self-supplied marketing copy |
| Conflicts of interest | Disclosed plainly | Usually hidden |
| Guarantees | None; probabilistic by design | Often promises fixed placement |
The public criteria
These are the kinds of public, checkable signals a neutral directory looks for. They mirror what a careful buyer should check too.
A visible explanation of how the agency works across engines, sources and measurement.
Visibility tracked with repeated prompt sampling over time, reported as rates and trends rather than anecdotes.
Clear about what is and is not included, the pricing model, and the limits of what AEO can influence.
Frames outcomes as probabilities, with no promise of a specific AI answer or a fixed placement in an engine.
Definition
A factual record of an agency's documented AEO services and sources, reviewed against public inclusion criteria. Inclusion is free and is not an independent endorsement or guarantee of results.
The profile records what publicly available evidence supports and its limitations at the time of review. Service languages are descriptive information and play no part in inclusion. Every portal profile is available in English and Spanish, regardless of the languages in which the provider works.
Grow the business
A listing helps you get found; the work below is what keeps clients once an AI engine sends them your way.
Most agencies reach AEO from an SEO base. Layer answer-level measurement, entity consistency and source work on top of technically sound sites.
Track ChatGPT, Gemini, AI Overviews, Claude, Perplexity, Grok and Copilot, since referral share shifts between them quarter to quarter.
Show mention, recommendation and citation rates over time. Honest reporting is itself a differentiator in a market full of guarantees.
FAQ
Use the For Agencies page to apply under the public inclusion criteria. An editorial profile may already exist from your public website; applying lets you confirm or correct it. We review the supporting information and publish factual profiles without selling inclusion or position.
No. Inclusion is based only on fixed public criteria: a published methodology, statistical measurement, transparent scope and no guaranteed-placement claims. No position in the directory can be bought.
The operator, Centro Publicidad Electrónica España, S.L., also operates Blobic. That affiliation is disclosed. All agencies follow the same public criteria, inclusion is free and ordering is by country and name. A profile is not an independent endorsement or certification of the provider.
Guaranteeing a specific AI answer or fixed placement, buying reviews or fabricating mentions, hiding the method, or claims that do not match the agency's public evidence. AEO is probabilistic, so promises of certainty are treated as a red flag rather than a selling point.
There is no guaranteed timeline or effect. Engines may discover a profile, but whether they cite or recommend an agency depends on their systems and the question, session and time. Evaluate any observed change with repeated measurements; do not assume the listing caused it.
Next step
Agencies can apply under the public criteria. Companies looking for a provider can browse the directory of AEO agency profiles instead of being sold to here.
