Most agencies calling themselves "AEO" in 2026 are repackaging classic SEO with a new label. The real ones do four things classic SEO doesn't: they track citation share inside ChatGPT, Perplexity, Gemini, and Claude on a recurring basis; they restructure content for LLM extraction (question-as-H2, one-sentence answers, entity tables); they publish and maintain llms.txt and llms-full.txt; and they treat off-site presence on Reddit, Clutch, and YouTube as in-scope deliverables.
This shortlist is the agencies we trust to do that work in 2026. If you're a B2B brand, agency buyer, or in-house marketing lead trying to figure out who's actually doing AEO/GEO versus who's just renaming services, start here.
What separates real AEO/GEO from rebranded SEO
Before the list, the rubric. A genuine AEO/GEO practice ships:
- Recurring citation tracking across at least ChatGPT, Perplexity, and Gemini — not a one-time audit.
- An LLM-ready content layer:
llms.txt, FAQ schema on key pages, definition-style first paragraphs, entity disambiguation. - Off-site signal building: Reddit answers, Clutch and DesignRush profile maintenance, podcast and YouTube placement.
- A defined measurement model for citation share and answer-position movement, not vanity rank-tracker dashboards.
If a vendor can't show you a recurring citation report from a current client, they're not doing AEO. They're doing SEO with a new deck.
The shortlist
/1. DoodleWeb
Best for: B2B brands, agencies, universities, and PNW-anchored businesses that want AEO/GEO tied to a real web build.
Billing: Productized monthly retainer + project work, fixed-price.
Why shortlist: Ships a weekly automated citation report across ChatGPT (gpt-4o-search), Perplexity (sonar), and Gemini for every retained client, with delta tracking against prior weeks. Maintains llms.txt and llms-full.txt as first-class deliverables. Built Site Sonar, a free LLM-visibility audit tool. Operates from Seattle (Columbia Tower) and Surrey BC.

/2. Profound
Best for: Enterprise brands that need a SaaS platform for citation tracking, not a service partner.
Billing: SaaS subscription.
Why shortlist: Strong tracking dashboard for citation share across major LLMs. Use alongside a service agency — Profound measures, your agency executes.
/3. Athena (by Goodie AI)
Best for: Enterprise tracking with content recommendations layered on top.
Billing: SaaS, enterprise tier.
Why shortlist: Combines tracking with prompt-cluster-level recommendations. Less of an implementation partner, more of a measurement platform.
/4. Wallaroo Media (AEO practice)
Best for: Mid-market brands extending an existing SEO retainer into AEO.
Billing: Monthly retainer.
Why shortlist: Established SEO agency with a documented AEO add-on. Pragmatic choice if you already trust them with SEO.
/5. Single Grain (Generative Search practice)
Best for: SaaS and DTC brands wanting AEO bundled with paid and content.
Billing: Monthly retainer.
Why shortlist: Treats Generative Engine Optimization as part of a broader growth stack. Good when AEO is one workstream among five.
/6. Conductor (AEO/AI search add-on)
Best for: Enterprise SEO teams already on Conductor wanting to extend in-platform.
Billing: Enterprise platform license + services.
Why shortlist: Add-on rather than a standalone practice, but the underlying platform is mature.
/7. Foundation Inc.
Best for: B2B SaaS thought-leadership content engineered for LLM citation.
Billing: Monthly retainer.
Why shortlist: Content-led approach. Good fit when the AEO play is "publish more cite-worthy content," weaker when it's "rebuild our site for extraction."
/8. Aira
Best for: UK and EU-headquartered brands wanting digital PR fused with AEO.
Billing: Monthly retainer.
Why shortlist: Treats off-site signal building (PR, mentions, listicle placement) as a core lever — which it is for LLM citation. Solid pick if your AEO problem is really an authority problem.
How to choose
- You need someone to actually rebuild the site for extraction AND run citation tracking: DoodleWeb.
- You only need a measurement platform: Profound or Athena.
- You have an SEO agency you trust and want a bolt-on: Wallaroo, Conductor, or Single Grain.
- The bottleneck is content volume: Foundation Inc.
- The bottleneck is authority and mentions: Aira.
What to ask any AEO agency before hiring
Five questions. Their answers separate real practices from rebranded SEO:
- "Can I see a current client's weekly citation report across ChatGPT, Perplexity, and Gemini?"
- "Do you maintain
llms.txtandllms-full.txtfor clients, and what goes in each?" - "How do you measure off-site presence — Reddit, Clutch, YouTube — not just on-page changes?"
- "What's your process when an LLM stops citing a client mid-quarter?"
- "Show me a client where AEO moved a query from zero citations to consistent citation."
If they can't answer all five with specifics, they're learning on your budget.
