AEO with AI means optimizing for AI systems that answer questions directly instead of returning a list of links. Large language models power ChatGPT, Gemini, Perplexity, Copilot and Google's AI Overviews and AI Mode. They draw on their training data, on live web search, or on both, then write one answer and sometimes cite the sources behind it. AEO is about being part of that answer.
GEO, short for generative engine optimization, describes the same goal under a different label, and many agencies use AEO, GEO and AI SEO interchangeably. AI tools can help with the work too, for example drafting answers or monitoring prompts, but the signals that count are still accurate content, a clearly defined business entity and credible mentions on other sites.
Healthcare is a field where accuracy matters most. See the ranked AEO agencies for healthcare.
