Ai Search
SGE (Search Generative Experience)
SGE (Search Generative Experience) was Google's AI-powered search experience launched in beta in May 2023 via Google Labs. In May 2024, SGE was rebranded as AI Overviews and rolled out globally to over 1.5 billion users.
Why SGE (Search Generative Experience) Matters for SEO
The businesses that adapted early to SGE had a head start on AI Overview optimisation. The speed of evolution — beta to global in 12 months — signals that AI search change will remain rapid. Understanding this history provides context for why AEO strategy has become urgent.
How SGE (Search Generative Experience) Works
SGE was opt-in and experimental while AI Overviews became the default for all users. The core mechanism is the same: generative summaries with source citations. The scale shift from a small test audience to billions of users is what changed the stakes for SEO practitioners.
Common Mistakes
- Treating AI Overviews as a temporary experiment that will go away
- Not studying how SGE evolved to anticipate future AI search changes
- Waiting for AI search to 'stabilise' before adapting strategy
