What is a GEO agency?
Generative engine optimisation is the practice of making content that LLM-based search systems reference, synthesise and cite. A GEO agency sells that as a service: it works on a brand’s pages so that AI answers pick them up and name the brand as a source.
The term comes from an academic paper, “GEO: Generative Engine Optimization” by Aggarwal et al., first submitted on 16 November 2023 and accepted to KDD 2024 (arXiv 2311.09735). In the market you will see the same work sold as AEO (answer engine optimisation), AI SEO or LLM optimisation.
Our inclusion rule is simple. An agency is listed only if it has a GEO, AEO or AI SEO service page on its own site, and we check that page by hand before the agency goes in. A general SEO shop that mentions AI once in a blog post does not qualify. The full rule is on the methodology page.
Top 10 GEO agencies by observed visibility
This is the top of the ranking from the 1 Nov 2026 panel run. Each agency is scored on how high its own domain appears in Google for the buying terms in our panel, across the UK, US and Singapore. It is not a quality rating and it is not an endorsement. It answers one question you can check yourself: has this agency become visible for the thing it sells?

Browse GEO agencies by market
Each market has its own panel of buying terms, run on Google for that country. An agency headquartered in one market can still score in another, so the hub pages rank everyone who shows up locally, not only local firms.
224 agencies in the three markets plus 47 elsewhere makes 271. City pages: London · New York. Buying in pounds? Start with GEO agencies in the UK.
How we rank GEO agencies, and why most lists can’t
On our 1 Nov 2026 panel of 61 buying queries, 162 of 271 agencies (60%) appeared in no top-20 result. Most of the “best GEO agency” pages that rank today are published by agencies that sell GEO, and few of them say how their order was decided. We publish ours, with the date, so anyone can re-run it.
A fixed query panel per market
22 UK terms, 25 US terms and 14 Singapore terms that buyers type when looking for a GEO, AEO or AI SEO agency. The UK panel runs with gl=uk.
Score every top-20 position
Position 1 earns 20 points, position 20 earns 1. An agency’s score is the total across every query where its own domain appears.
Re-run monthly, publish the date
Same panel, same scoring, every month. The run date sits on every ranking page so you know how fresh it is.
One limit, stated plainly: the panel measures Google results only. It says nothing about whether an agency is cited by ChatGPT or Perplexity, and nothing about the quality of its client work. It is a first filter, not a verdict.
AEO vs GEO vs AI SEO: what’s the difference?
The three terms overlap, and agencies use them interchangeably. AEO is usually the narrowest: answer-focused content, FAQ and definition blocks, structured data. GEO is the broader, academic term for being cited inside AI-generated answers. AI SEO is the loosest label and the most commercial. Pick the list that matches the words your team already uses; the scoring is the same on all three.
Tags overlap: one agency can carry two or three, so the counts do not add up to 271.
How to choose a GEO agency
There is no single right agency, but five questions separate a real GEO practice from a relabelled SEO retainer. Much GEO work overlaps classic SEO, so ask what is genuinely different about theirs.
- Does it rank for its own service?
An agency selling visibility should have some. Every profile here shows the agency’s own score and the terms it ranks for, so this test takes ten seconds.
- Is there a named GEO service page?
Look for a page that describes the GEO, AEO or AI SEO work itself, not one line on a general SEO page. We link the page we checked on each profile.
- Which engines does it cover?
One engine is not “AI visibility”. Ask which answer engines they track and report on. Each profile lists the platforms the agency names.
- Will it give you a dated baseline and the raw prompt log?
Ask for your citation rate before the work starts, with the prompt list and the dates behind every metric. Without that, any later improvement can’t be checked.
- Does it implement, or only advise?
Find out who writes and publishes the pages, and who else the agency serves in your category.
For agencies
Every listing is free, and nothing you buy can move you up. If your agency sells GEO, AEO or AI SEO and is missing, submit it. If you are listed and something is wrong, claim the listing and tell us what to fix. Scores refresh monthly from the same fixed panel, so the way to climb is the advice you already give clients: rank for the terms.

GEO agency directory FAQ
What is a GEO agency?
A GEO agency sells generative engine optimisation: work to make a brand’s content get referenced and cited by LLM-based search systems. AEO and AI SEO are overlapping labels for similar services. We list an agency only if it has a GEO, AEO or AI-SEO service page that we have checked by hand.
How are agencies ranked in this directory?
By observed search visibility. We run a fixed panel of 61 buying queries across the UK, US and Singapore, and score each agency by how high it appears in the top 20 results. The score is the sum of (21 − position) across the panel. The method is on the methodology page, and the last run was 1 Nov 2026.
Is it free to be listed, or to use the directory?
Yes, both are free. There is no paid or featured placement, and no agency can pay to move up. Agencies can claim a profile to correct it or submit a missing agency.
How often is the ranking updated?
Monthly. The panel is re-run and the scores recomputed, and the run date is shown on the page. The current ranking is from 1 Nov 2026.
What does a score of zero mean?
162 of 271 agencies (60%) appeared in no top-20 result for any query in our panel on 1 Nov 2026. The panel measures Google results only. It does not measure whether an agency is cited by ChatGPT or Perplexity, and it says nothing about the quality of the work.
Which GEO agency is best for B2B SaaS?
We don’t name a single best agency. Use the filters on the GEO, AEO and AI SEO lists to build a shortlist, check each profile’s own visibility and the engines it covers, then ask for a dated baseline. Or send one brief and we will match you with up to three agencies.
