Ranked by confirmed customers, then by all confirmed relationships, then by name. A relationship counts when the entity on the other side holds a verified website. This list covers every agency that sells generative engine optimisation, GEO for short, as a service and offers it in English, wherever it is based, from the United States and Canada to the United Kingdom, Ireland, Australia, New Zealand and India, for businesses from SMBs to large enterprises. Software that measures a brand's visibility in AI answers has its own list, [Best AI Visibility Tools](https://markleex.com/en/lists/ai-visibility-tools). GEO is the work on how ChatGPT, Perplexity, Gemini, Claude and Google's AI Overviews name and describe a brand in their answers. The agencies below find the prompts that matter, measure how the engines present a brand today, shape its content, structured data and technical foundations so machines can read and cite it, and earn mentions on the sources the engines trust. They differ in where they come from, whether SEO, content, digital PR or website building, in whom they serve, and in size, from a founder-led team to agencies of more than three hundred people. The list is ranged by language, and a space appears in it as soon as it publishes its pages in English. An agency joins by asking, with a website verified on Markleex; Markleex reads every request before accepting it, and the price is the same for everyone. The other names are the ones we found looking for the sector. This list ranks them on facts Markleex attests: first the customers who confirm an entity, then all the relationships confirmed by other entities. When the facts are equal, alphabetical order decides. Rank is earned, and it is the same for everyone. The write-ups are ours. We read each agency's website and describe what we found there, in one voice for every entry, so the list reads end to end. ## 1.
