Google AI Overview is the AI-generated answer block that now appears at the top of Google search results for a significant and growing proportion of queries — currently around 40% of UK searches.
It gives one synthesised answer. Often with a short list of recommended businesses or resources. One answer. Above everything else on the page.
It was previously known as SGE — Search Generative Experience — during Google's testing phase. Google renamed it AI Overview when it launched publicly in 2024.
For local business queries — "best electrician in Leicester," "solicitor for employment law Northampton," "accountant Derby" — a business in AI Overview is the recommendation. A business in position one is a link below the recommendation. The difference in visibility is significant.
In practice, the technical signals that drive AIO performance are largely the same as those that drive AEO and GEO. Getting the signals right for one gets you most of the way to all three.
For years, the goal of search optimisation was ranking number one on Google. Position one meant appearing at the top of a list of ten links.
AI Overview changes that calculation. When Google generates an AI Overview for a query — and it does so for roughly 40% of searches, a proportion growing every month — the AI Overview sits above position one. Above every link. Above every ad.
Most small businesses are not in AI Overview for any query. Not because they are not good enough. Because they are missing the specific technical signals Google uses to populate it.
Google AI Overview is the fastest of the three AI search disciplines to respond to new signals. Unlike ChatGPT, which relies on periodic training data updates, Google AI Overview draws on Google's live search index, which updates continuously.
New schema markup and Google Business Profile changes typically influence AI Overview results within two to four weeks for most local business queries. For businesses implementing these signals for the first time, that is a fast turnaround relative to the long-term competitive advantage of appearing consistently.
