Top 10 GEO Agencies (Generative Engine Optimization)

Generative Engine Optimization (GEO) agencies specialize in helping brands get discovered in AI-generated content and large language model outputs. These firms go beyond traditional SEO to ensure companies are cited in AI answers, overview snippets, and conversational search results.

That includes appearing in ChatGPT’s or Google’s AI-generated lists on queries like “what is the best tool to do X” or “what are the top 5 apps best for Y”. In essence, any question that implies the need for a product or service will have LLMs dig through available data to recommend one. By 2026, being mentioned in those replies will be the most important metric.

Let’s examine the top 10 agencies that promise success with GEO optimization and have already shown clear signs of refining their service offerings, providing a clear path to increase mentions through large language models and AI overviews.
