Definition
Search Generative Experience (SGE) was Google's experimental generative AI layer for Google Search, offered through Search Labs from May 2023 until May 2024, when it graduated into the feature now called AI Overviews. SGE is a historical term: Google told Search Engine Land at the time that the feature should be called AI Overviews and not SGE, and current Google documentation does not use the name.
Google announced SGE at I/O in May 2023 as its response to ChatGPT. Users in the US who opted in through Search Labs saw an AI-generated snapshot above the classic results, with source links, suggested follow-up questions and a conversational mode for refining a query. Snapshots appeared only for some queries. In March 2024 Google began showing these AI answers to a subset of users who had not opted in.
At Google I/O on May 14, 2024, Google said people had already used AI Overviews 'billions of times' through the Search Labs experiment and began rolling them out to everyone in the US, with a target of more than a billion users by year end (Google's announcement). The launch was rocky. Viral screenshots of odd answers led Google to publish a follow-up on May 30, 2024 explaining the errors and tightening when AI Overviews appear. Expansion continued anyway: more than 100 countries by October 2024 and more than 200 countries and territories in over 40 languages by May 2025. France, one of the last large holdouts, received AI Overviews and AI Mode together on July 22, 2026.
The conversational side of SGE lives on in AI Mode, which Google tested in Search Labs from March 2025 and rolled out in the US that May. At I/O in May 2026, Google said AI Overviews had more than 2.5 billion monthly active users and AI Mode more than 1 billion.
Some mechanics that were rough in SGE are now documented. Both AI Overviews and AI Mode use query fan-out, running several related searches across subtopics and citing a wider set of pages than one classic results page would. Publishers also gained controls SGE never had: since August 31, 2026, any site can use the Search generative AI control in Google Search Console to opt out of AI Overviews, AI Mode and generative features in Discover, and a generative AI performance report shows impressions from those features.
For GEO work, treat 'SGE' as a label on older articles and tools. Advice written for SGE in 2023 often assumed a single snapshot per query and US-only availability, neither of which holds today. When you see 'SGE optimization' in a brief or a vendor pitch, translate it into the current targets: citations and mentions in AI Overviews and AI Mode, measured per country. Our guide to optimizing content for Google AI Overviews covers the current approach, and generative AI search explains the wider category.
Examples of Search Generative Experience (SGE)
- In mid-2023, a US user enrolled in Search Labs searches 'best hikes near Denver for kids' and gets an SGE snapshot with three trail suggestions, source cards from local outdoor blogs, and an option to ask a follow-up question.
- An SEO agency audits a client's 2023 content brief titled 'SGE optimization checklist' and rewrites it around AI Overviews and AI Mode citations, adding country-level tracking because the client sells in Germany and France.
- After Google's May 14, 2024 launch, a recipe site sees AI Overviews appear for 'how long to boil eggs' and loses clicks on that query, while long-tail questions like egg timing at high altitude still send traffic.
- A publisher in the UK reads 2023 forum threads saying SGE content could not be opted out of, then checks Search Console in September 2026 and finds the Search generative AI control now available for its property.
