GEO agencies — the buyer's guide

How to choose a GEO agency

The bar to call yourself a "GEO agency" is currently low. Most offerings are dashboards, or repackaged SEO services. Here's the seven-question checklist we use ourselves when we evaluate a vendor on a client's behalf.

1. Do they name the engines? A GEO agency that says "we track AI" without naming ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews is a red flag. Each engine has its own bias.
2. Do they show a prompt corpus? Buyers want a sample of the actual buyer-intent prompts they sample, not just a generic "200 prompts".
3. Do they distinguish GEO from SEO and AEO? If they use the terms loosely, the work is loose. SEO, AEO (Answer Engine Optimization), and GEO overlap — but a credible agency explains the difference.
4. Do they ship the action layer? Measurement without remediation is a dashboard. Ask if they generate content, schema, and distribution — or if they only report.
5. Do they show real before/after numbers? Case studies with concrete mention-rate, citation-count, or share-of-voice lifts beat adjectives.
6. Do they name competitors in your market? If they refuse to, the work is generic. A good agency will benchmark you against named local and global rivals.
7. Do they report leading indicators weekly? AI visibility moves slowly, on a timeline nobody has established. If they only report quarterly, you will be flying blind for two quarters.

The agencies AI engines name globally

Measured rather than asserted. On 11 August 2026 we put twelve buyer-intent questions to ChatGPT, Claude, Perplexity and Google AI Overviews and recorded every brand named across 36 usable answers. This is who came back, and how often.

On the agency-specific questions the engines also named Goodie, NP Digital, Single Grain, Amsive, Ahrefs, BrightEdge and Bluetext.

Read the third column before you use this as a shortlist. Roughly half the names the engines return for "best GEO agency" are software products, not agencies. The engines assemble names from pages that mention them near the right words, and a "top 10 AEO tools" listicle looks much like a "top 10 AEO agencies" listicle to a retrieval system, so the categories bleed. That is a fact about how the answer is built, and it applies to your category too.

We include ourselves at 11% because leaving ourselves out would be coy and putting ourselves top would be false. The full run, the method, and the previous month where we scored higher are on our numbers. The longer analysis is in the AEO and GEO agencies AI engines name, and the tool-by-tool comparison is in Profound alternatives.

How Word of GPT fits in this list

Word of GPT is a GEO studio run by engineers. We measure AI Share of Voice across five engines, then build the agent infrastructure that moves the number — content, schema, programmatic pages, drafted distribution. We compete with the agencies above on every prompt we run. The reason we built this page is to be honest about the market: if you want a list of pure-play GEO agencies in your city, the ones we benchmark against are the most credible options, and we name them.

Our pricing sits in the same range as the agencies on this page, scoped to your market and commitment rather than a fixed menu. Our differentiator is the action layer: the agents that ship the content, schema, and distribution, not just a dashboard.
