Definition
AI Overviews (formerly Search Generative Experience, SGE) are the Google-generated summaries that appear above the classic blue links for many queries. Instead of ten links, Google delivers a direct answer - assembled from several sources, each named with a link.
For brands this changes the rules: the decisive position is no longer rank 1 of the links, but being named as a source in the AI answer. Many searches end without a click ('zero-click') because the answer already sits complete in the box - the mention matters more than the visit.
Important: AI Overviews and the separate 'AI Mode' are two different engines - for the same query they cite the same URLs only about 14% of the time. Overviews favour already well-ranking pages anyway; AI Mode weights freshness and entity authority more heavily. Visibility follows the same principles as GEO.
Why it matters
AI Overviews sit above everything else and often answer the query completely. Not appearing there as a source loses visibility even with top rankings in the classic results below.
In practice
- 01A search for 'best CRM for small teams' shows an AI summary naming three providers - the rest are effectively invisible.
- 02A clearly phrased definition with clean structure gets pulled into the overview box more often than a tangled wall of text.
- 03Informational searches ('what is GEO?') are often answered without a click - the source citation replaces the visit.
