What is AIO? AI Optimisation and AI Overviews explained

AIO as AI Optimisation

In marketing, AIO most often means AI Optimisation: improving how AI tools such as ChatGPT, Gemini, Perplexity, Copilot and Claude understand, describe and recommend a business. It is an umbrella term, used the same way as AI SEO, AEO and GEO.

AIO as Google AI Overviews

In SEO circles, "AIO" is also shorthand for Google AI Overviews, the AI-generated summaries Google shows above its normal results for many searches. "AIO optimisation" in this sense means getting your pages used and linked as a source in those summaries, and in Google's AI Mode. We cover that in how to appear in Google AI Overviews and AI Mode.

AISO, LLMO and other variants

You will also see AISO (AI Search Optimisation), LLMO or LLM SEO (Large Language Model Optimisation) and AI search optimisation. These are different labels for the same discipline. Our glossary defines each, and AEO vs GEO vs AIO vs AI SEO explains where they differ in emphasis.

What AIO work involves

• Entity and schema: making it unambiguous who you are, what you do and where.
• Answer-ready pages: content that answers real customer questions in the first paragraph.
• Google Business Profile: a complete, consistent profile, which feeds Google's AI features and Maps.
• Citations: credible third-party mentions that confirm your details.
• Measurement: tracking how often AI names you across a fixed set of questions.

Which term should you use?

Whichever your team understands. What matters is agreeing on the outcome, which is AI visibility: being named when customers ask AI for a recommendation.
