One goal under five names
The agency's section begins from a plain observation: the industry has not settled on a single name. Whatever it is called, the goal is the same: when someone asks an AI assistant for a business, that business's name should be in the answer, described accurately, with a reason to choose it. The agency calls it AEO and then lines up the other four terms against it.

AEO and GEO
AEO is the agency's own term. Its definition names the places a business should become the answer: ChatGPT, Gemini, Perplexity, Claude, Google's AI Overviews and voice assistants. GEO, generative engine optimization, is the same work named for the generative engines that write answers in place of a list of links.

AIO and AI SEO
AIO, AI optimization, is the broadest of the five: making a business easy for AI systems in general to understand and trust, and so to recommend. AI SEO is the term closest to traditional search. It covers SEO adapted for AI-powered search, including Google's AI Overviews and AI Mode.

How the terms relate to SEO
The agency's FAQ answers the obvious follow-up. AEO and SEO overlap, but SEO focuses on ranking a website in a list of links, while AEO focuses on whether AI systems mention and recommend a business inside their written answers. That depends on listings, reviews, structured data, third-party sources and how clearly a site answers real questions.
