A Google AI Overview (formerly called Search Generative Experience, or SGE) is an AI-generated summary that appears at the very top of Google search results above the traditional blue links. It is produced by Google's Gemini model, which reads and synthesises multiple web pages to generate a direct answer to the user’s query.
Unlike a featured snippet, which pulls a single passage from a single page, an AI Overview aggregates information from several sources and presents it as a unified, conversational response. The sources cited appear as small cards alongside the summary.
AI Overviews were rolled out globally in May 2024 and are now a permanent feature of Google Search. They appear most frequently on:
- Informational queries (“what is”, “how does”, “why does”)
- How-to and step-by-step queries
- Comparison queries (“X vs Y”)
- Definition and explanation queries
Commercial and transactional queries (product searches, local searches, brand searches) are less affected for now.
