How we checked

We opened each agency’s own website and kept it only if it described an AI search, GEO or AEO service. Agencies do not pay to appear here.

GEO, AEO and AI SEO: what the terms mean

You will see three names for this work. They overlap heavily:

  • GEO (generative engine optimisation): improving how often AI models such as ChatGPT, Gemini and Claude mention and cite your brand.
  • AEO (answer engine optimisation): structuring content so answer engines, AI Overviews and voice assistants can pull a direct answer from it.
  • AI SEO / LLM SEO: a catch-all term for SEO adapted to AI search, usually covering both of the above plus AI visibility tracking.

Frequently asked questions

What is the difference between GEO and SEO?
SEO aims to rank your pages in search results. GEO aims to get your brand named, recommended or cited inside AI-generated answers. Most GEO work builds on SEO rather than replacing it.
Is GEO the same as AEO?
Mostly. AEO started with featured snippets and voice search, and GEO with large language models. Agencies use the terms loosely and often sell them as one service.
How are agencies added to this list?
We add an agency only after checking that its own website describes an AI search, GEO or AEO service. Listings are free and are not ranked by payment.
My agency offers GEO. How do I get listed?
Use the form on List Your Agency. If you are already listed, open your listing and use the Claim this listing box to ask us to add you to this category.
