Methodology

How we chose and ordered them.

1. GEO as a named service (required)

Every agency here offers GEO, AEO or AI search visibility as a defined service on its own site.

2. How AI visibility is measured

We ranked higher agencies that explain how they track prompts, mentions and citations, and publish results in those terms.

3. Proof and transparency

Named case studies, and published pricing where it exists.

4. A real office

Every agency here states a street address on its own website. Several well-known names did not, on the pages we could read.

What we did not do

We did not hire these agencies, test their AI results ourselves, or accept payment from any of them. We did not compare review platforms, which cover these agencies unevenly.

Choosing

How to choose a GEO agency.

Ask for the prompt set

A serious GEO agency tracks a fixed list of questions your buyers ask in ChatGPT, Perplexity, Gemini and Google, and reports mentions and citations over time. Ask to see it before you sign.

No one can guarantee a citation

AI answers change between runs and models. Agencies can make you easier to cite; they cannot promise you will be.

Check the SEO foundations come first

AI tools draw heavily on pages that already rank and on trusted third-party mentions. GEO without crawlable, well-structured pages and real PR is mostly theatre.

Match the price to your stage

The one agency here that publishes a price starts at $120,000 a year. Offshore agencies can do the same core work for less; judge on method and reporting, not just price.

Prefer real examples

Because the field is new, a named case study showing citations gained tells you more than a service page.

Questions

Common questions, answered.

What is GEO?

Generative engine optimisation aims to get your brand mentioned or cited in AI answers from tools like ChatGPT, Perplexity, Gemini and Google's AI Overviews and AI Mode.

Is GEO different from AEO?

The terms overlap. AEO usually means structuring content to be the direct answer, in snippets and AI Overviews; GEO is broader, covering mentions and citations across AI assistants. Many agencies use them interchangeably.

How much does a GEO agency cost?

Among agencies that publish figures, engagements start around $120,000 a year at the top end. Smaller and offshore agencies charge much less. Ask what is tracked and delivered each month.

Why is Digiradix shown first?

Digiradix wrote and publishes this guide. To keep the ranking fair, we left ourselves out of it and introduced ourselves in a separate, clearly labelled box instead. We think we are a strong choice too, so judge us by the same criteria we used for everyone else.

How long does GEO take?

Brands with strong SEO and PR can see more AI mentions within a few months; others need that groundwork first.

Can I get my company added or corrected?

Yes. Email us with the change and a source we can check. We review requests within a week and re-verify every company on this page every six months.

Last verified 20 October 2026. Company details change; if something here is out of date, email hello@digiradix.com and we will correct it within a week. More guides are in agency guides.

Does ChatGPT know your business exists?

Tell us your business and the questions your buyers ask. We will check how you show up in AI answers today, and tell you honestly what it would take to improve.
