SGE was the beta name Google used while testing generative answers in Search Labs. When the feature reached general availability it was renamed and refined into AI Overviews.
Why the term still matters
Older documentation, third-party tools, and internal reports frequently reference "SGE". Anyone reading historical SEO research needs to know it means the same underlying concept.
Example
A 2023 industry study reporting "SGE reduces click-through rate by X%" is describing the same behaviour now attributed to AI Overviews.
How SEM Optimiser reports it
SEM Optimiser standardises on "AI Overview" for new features and treats "SGE" as a historical alias in the glossary and search.
