Term
SGE / AI Overviews / AI Mode
Google's AI-generated SERP answers. SGE was the beta name (2023), AI Overviews the production name (May 2024), AI Mode the dedicated chat tab (2025).
SGE / AI Overviews / AI Mode — explained in more detail
Three names for one trajectory: Search Generative Experience (SGE) was the Search Labs beta starting in 2023. In May 2024 it shipped as AI Overviews in the US, then rolled out to more markets — a generated answer at the top of the SERP with source boxes and follow-up questions. AI Mode arrived in 2025 as a dedicated tab (comparable to ChatGPT, embedded into Google Search).
The mechanic: Google retrieves relevant web pages for the query, summarizes their content with Gemini, and cites the sources. Being cited as a source in AI Overviews becomes its own SEO discipline (often called GEO — Generative Engine Optimization).
Example / In practice
Levers for AI Overview visibility: clearly structured content (headings, short paragraphs, FAQs), direct answers to specific questions, structured data for context signals, brand mentions on third-party sites as trust signals. Click-through on SERPs that include AI Overviews drops measurably — appear in the answer box and you benefit; sit below it and you usually lose traffic.
Distinction from similar terms
A Featured Snippet is a verbatim extract from a single page (deterministic). An AI Overview is a generated, multi-source summary (variable, paraphrased). AI Mode is a dedicated chat tab, not a SERP component — it competes more directly with ChatGPT, Perplexity, etc.
