Gemini
What is Google Gemini?
Gemini is Google's most capable family of AI models, developed by Google DeepMind. Released in December 2023, Gemini comes in three sizes: Nano (on-device), Pro (general purpose), and Ultra (the most capable). As of 2026, Gemini powers many of Google's AI features across its product ecosystem.
Gemini is significant for GEO because it's the AI model behind Google AI Overviews — Google's AI-generated search summaries. As Gemini becomes more capable and integrated, its impact on search visibility grows.
Why Gemini matters for GEO
Gemini is integrated into:
- Google Search — AI Overviews and search generative experiences
- Google Workspace — Gemini in Gmail, Docs, Sheets, Meet
- Android — Gemini Nano for on-device AI
- Google Cloud — Gemini API for enterprise applications
- Pixel devices — Gemini-powered features
With Google processing over 8.5 billion searches per day, Gemini's role in AI Overviews makes it a critical AI engine to monitor for any brand doing SEO.
Gemini and Google AI Overviews
Google AI Overviews, powered by Gemini, have expanded from initial testing in 2023 to appearing for approximately 30% of all Google searches by 2026. Brands need to monitor their AI Overview presence as a core part of any modern SEO strategy.
