Multimodal Search
Multimodal search allows users to combine multiple input types—text, images, voice, and video—in a single interaction. Instead of typing keywords alone, users can point their camera at a product while asking "Where can I buy this nearby?"

Why It Matters
In March 2026, Google launched Search Live globally across 200+ countries, powered by the Gemini 3.1 Flash Live model. Real-time multimodal search using smartphone cameras and voice is now mainstream. 27% of mobile users already search by voice, and Google Lens processes over 12 billion visual queries per month. Sites implementing multimodal optimization report 30–50% higher search visibility compared to text-only approaches. Relying solely on keyword-based SEO means missing traffic from image, voice, and video-driven discovery.
Types of Multimodal Queries
| Type | Example |
|---|---|
| Text + Image | Upload a product photo and ask "Any cheaper alternatives?" |
| Voice + Camera | Point at a broken pipe and ask "What's this part called?" |
| Voice + Location | "Where can I buy these shoes nearby?" |
| Document + Voice | Upload a PDF and ask "Summarize page 3" |
| Video + Text | Share a clip and ask "Where is this scene filmed?" |
