An AEO agency is a marketing firm that helps businesses get mentioned, cited and recommended in AI-generated answers from tools like ChatGPT, Google AI Overviews, Perplexity and Gemini. Typical services include prompt research, AI visibility audits, content rewritten to answer questions directly, entity and schema cleanup, digital PR aimed at the sources answer engines cite, and ongoing tracking of mentions across engines.
Many are established SEO agencies that added AEO, and some sell the same work as GEO or AI SEO. Quality varies a lot. Ask to see prompt-level tracking, named case studies and evidence in your industry before you sign.
