If your brand is invisible in ChatGPT, Perplexity, or Gemini answers for your category, you likely need an AEO agency, not another tracking tool. The difference between the two is the difference between seeing the problem and fixing it. This guide covers how we evaluated the top generative engine optimization agencies, who made the list, and the questions to ask before hiring.

What Is an AEO Agency, and Why Are Brands Hiring One Now

An AEO agency manages the work of earning organic citations in AI-generated search answers. That includes tracking visibility across AI engines, optimizing content for extractability, building entity clarity, and connecting AI search performance to business outcomes.

AEO vs. SEO vs. GEO: What Is Actually Different

SEO earns rank position in Google and Bing. GEO (Generative Engine Optimization) earns citations in AI-generated answers. AEO (Answer Engine Optimization) is used interchangeably with GEO in most contexts. 

All three share foundational work (content quality, structured data, authority building), but GEO and AEO add a measurement layer (tracked prompts, citation rate, share of voice) and an optimization layer (extractability, entity clarity) that traditional SEO does not cover.

Signs Your Brand Needs AEO

You may need an AEO agency if:

• Your brand has zero citations in ChatGPT, Perplexity, or Gemini when someone asks about your category

• Competitors appear in AI-generated recommendations, and you do not

• Your SEO metrics are stable, but you are losing market share to brands that show up in AI conversations

• Your team does not have the infrastructure to track AI visibility across multiple platforms

How We Evaluated the Best AEO Agencies

We evaluated based on four criteria that separate agencies with real GEO capability from those that relabeled existing services.

Criteria

• Citation tracking depth: does the agency track citations across ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews, and Copilot, with multi-sample runs per prompt?

• Managed execution vs. self-serve: does the agency ship the content, technical, and authority work that moves citation rates, or does it only provide a dashboard?

• Revenue attribution: can the agency connect AI search visibility to actual revenue through GA4, Search Console, or CRM integration?

• Platform coverage: does the agency optimize for all major AI engines, or only Google AI Overviews?

The Best AEO Agencies and Platforms

A quick look at the agencies and platforms helping brands track and improve visibility across AI search.

Passionfruit: End-to-End Managed SEO and AEO

Passionfruit runs SEO and GEO as one system with proprietary tracking, in-house expert execution, and keyword-level revenue attribution. The four-channel system covers Google, AI engines, community (Reddit), and programmatic as one motion rather than separate workstreams.

Proof points include 500+ brands, $1B+ revenue driven, 10.5M AI search traffic, and case study results like +23% AI revenue in 30 days and +257% US organic revenue month-over-month. The full results library is in the case studies section.

Where Passionfruit is strongest: end-to-end execution under one owner, revenue-by-keyword attribution (described on the site as first of its kind), and proprietary tracking through Passionfruit Labs.

Profound: Enterprise AI Visibility Intelligence

Profound is an established AEO platform, strongest in enterprise-scale AI visibility tracking with deep prompt analysis and competitive intelligence. Best for large organizations that need extensive monitoring across AI engines. Profound is a tracking and intelligence platform, not a managed execution service, so teams using it need a separate workflow for the content and technical work.

AthenaHQ: AI Search Monitoring and Optimization

AthenaHQ offers dedicated AI visibility monitoring with prompt tracking, competitive analysis, and citation monitoring. Best for teams that want a focused AEO platform without the scope of an enterprise tool. Like Profound, it is primarily a measurement platform.

Peec AI: AI Visibility Analytics

Peec AI provides AI visibility tracking with a clean interface designed for marketing and SEO teams. Strong on citation insights, competitor comparison, and trend reporting. Best for teams new to AI visibility tracking who want an accessible entry point. It does not include managed execution.

Scrunch AI: Enterprise GEO

Scrunch AI focuses on generative engine optimization and brand intelligence at enterprise scale. Strong on AI visibility monitoring and competitive tracking. Best for organizations with larger GEO and AI visibility requirements. Its enterprise orientation may be more than smaller teams need.

BrightEdge: Enterprise SEO Expanding into AI Search

BrightEdge comes from enterprise SEO and has added AI visibility tracking to its existing content intelligence platform. Best for large organizations already using BrightEdge for SEO who want AI search data in the same system. Its AI features are an extension of an SEO platform rather than a purpose-built AEO system.

Questions to Ask an AEO Agency Before Hiring

A few practical questions can help you understand what an agency actually handles beyond the reporting dashboard.

Do They Track Citations Across All Major AI Engines?

Ask specifically which platforms they monitor. ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews should all be covered. Ask how many times per cycle they run each prompt. Single-sample checks are unreliable.

Do They Tie AEO Work to Revenue, Not Just Visibility Scores?

Visibility metrics matter, but they are not the bottom line. Ask for a specific example of how AEO work was connected to revenue or pipeline. If the answer stops at citation rate, the measurement may not match your business goals.

Is This a Managed Service or a Self-Serve Dashboard?

This is the single most important question. A managed service ships content, technical changes, and authority work on your behalf. A self-serve dashboard shows you the data and leaves execution to your team. Both are valid. The wrong choice is buying one while expecting the other.

AEO Agency vs. Self-Serve AEO Tools: Which Fits Your Team

If your team has in-house GEO expertise and needs measurement data, a self-serve AEO tool is the right fit. If your team needs the content, technical, and authority work executed on their behalf, an AEO agency or managed partner handles both measurement and action.

The choice is not about which model is better. It is about whether you need analytics or execution, or both.

Your First Move

Identify whether your brand appears in AI-generated answers for your category. If it does not, determine whether the gap is in content extractability, entity clarity, structured data, or off-page authority. That diagnostic tells you whether you need a tracking tool, a managed partner, or both.

Frequently Asked Questions

What Is the Best AEO Agency for Small Businesses?

Small businesses benefit most from an agency that includes both tracking and execution, because they typically do not have the internal team to act on tracking data alone. Look for managed services with month-to-month contracts and custom scoping that fits smaller engagement sizes.

What Is the Best AEO Agency for Enterprises?

Enterprises with existing SEO infrastructure may prefer a platform like Profound or BrightEdge for tracking, paired with internal or partner execution. Enterprises without in-house GEO capability benefit from a fully managed partner that handles both measurement and action.

How Much Does an AEO Agency Cost?

AEO agency pricing depends on platform coverage, content volume, prompt set size, and whether the engagement is tracking-only, advisory, or fully managed. There is no standard rate. Ask for a custom scope based on your actual needs.

What Questions Should I Ask an SEO Agency Before Hiring for AEO Work?

Ask which AI platforms they track, whether they run multi-sample prompt runs, whether they can tie results to revenue, whether the team is in-house or subcontracted, and whether they have case studies showing AI visibility improvements alongside business outcomes.

Can I Use an AEO Tool and an AEO Agency Together?

Yes. Some brands use a self-serve tool for ongoing monitoring and an agency for periodic execution sprints. The coordination cost is the tradeoff: the tool and the agency need to share prompt sets and measurement methodology to avoid working on different signals.

What Is the Difference Between a GEO Agency and an AEO Agency?

In practice, GEO and AEO are used interchangeably. Both refer to optimizing your brand's presence in AI-generated search answers. The underlying work (citation tracking, content extractability, entity optimization, authority building) is the same regardless of which term the agency uses.
