Discover how voice, image and video search are transforming SEO in 2025—and how to optimize content for multimodal discoverability and rising trends.
Search isn’t just about text anymore. In 2025, users find information via voice, images, video—across assistants, smartphones, AR. To stay ahead, you must adapt your content, technical setup, and signals to support multimodal search: optimizing media, using schemas, focusing on UX across platforms. This guide shows what works—and what matters most in this shift.
Modern search is evolving—and fast. Once, optimizing around keywords and backlinks was enough. Now users expect to use their voice, upload images, watch videos, or mix all three to discover content. Voice assistants like Alexa/Siri, image-based tools like Google Lens, and video platforms are pushing SEO into a multimodal era. If your content strategy still centers only on text, you risk missing huge traffic. Let’s explore what multimodal search really means, how it works, and exactly how to adapt in 2025.
⤷ What Is Multimodal Search?
- Definition: Search that takes more than one input type — voice, image, video, text — to satisfy queries.
-
Examples:
Voice query: “Show me how to fix a leaky faucet” (spoken).
Image query: User takes photo of plant, asks “What plant is this?”
Video search: Text + video combo, or video thumbnails being surfaced in SERPs. -
Why it matters now:
Smartphone adoption + smart assistants growth.
Better on-device image recognition.
More video consumption, more platforms supporting search in video/audio.
