Search Generative Experience (SGE)
Search Generative Experience (SGE) was Google’s experimental version of search that added AI-generated answers to the top of results. Announced in May 2023 and offered through the Search Labs programme, it was the forerunner of AI Overviews, which replaced the SGE name when Google launched the feature publicly in 2024.
How SGE worked
SGE was announced at Google I/O in May 2023. Users in the United States could opt in through Search Labs, Google’s area for testing new features. For some queries, SGE showed a generated snapshot above the normal results. It combined a large language model with Google’s search systems, so the answer drew on pages from the index and showed links to sources.
Features tested during the experiment included:
- AI snapshots summarising an answer, with source links.
- A conversational mode for asking follow-up questions.
- Shopping summaries that drew on Google’s product data.
- Different layouts for showing sources, which changed many times.
SGE later expanded to more countries and languages while still in testing.
From SGE to AI Overviews
At Google I/O in May 2024, Google launched AI Overviews to all users in the United States, effectively ending the SGE experiment under that name. AI Overviews then rolled out to other countries, including the UK. Google later added Google AI Mode, a fuller conversational search experience that builds on the ideas SGE tested.
What SGE taught SEOs
- Generated answers would take space at the top. This raised concerns about zero-click searches and lower click-through rates for informational queries.
- Sources were not always the top-ranking pages. Cited links sometimes came from lower positions or related queries.
- Answer-friendly content mattered. Clear, well-structured explanations were easier for the system to use, which encouraged interest in answer engine optimisation and generative engine optimisation.
- Experiments change fast. Layouts and triggers shifted often, so early conclusions did not always hold.
Why the term still appears
You will still see SGE used in older articles, tools and conversations, sometimes loosely to mean any AI-generated result in Google. In current Google terminology, the correct names are AI Overviews and AI Mode. When reading advice about SGE, check the date, as much of it was based on an experimental product that has since changed.
Common misunderstandings
- SGE was never a separate search engine. It was a set of features tested inside Google Search.
- Optimising for SGE did not require special markup, and the same is true for AI Overviews today.
- Data from the SGE period is not a reliable guide to current AI Overview behaviour, because the product, models and triggering have all changed.
