Visual & Multimodal Content
Images, video and infographics are entry points in their own right. How to optimize visual content for Google Lens, image search and multimodal AI.
Content is more than text. That has been true for a long time, but it became a serious SEO question when the search engines stopped treating images as decoration and started reading them as content. Today a user can photograph a product and have it identified, ask a question about a picture and get an answer back, or find you through a video without ever seeing your front page.
This is what multimodal search means: the question can be asked in one format and answered in another. For you it means every image, video and graphic is a possible way in, and that they need the same care as a text page.
Why it matters now
Three things have moved visual content from nice to necessary.
Image search is a channel of its own. Google Lens and Pinterest Lens get used by people with high purchase intent. They have seen something they want, and they search for it the way they met it, with the camera. Furniture, fashion, interiors, tools and building materials sit especially high.
The models are multimodal. Google's MUM and the language models driving the AI answers interpret text and image within the same question. That raises the value of having your images correctly described, correctly named, and surrounded by copy that explains what they show.
Bing indexes graphical content more broadly than Google. The engine crawls images, video and audio more extensively and ties them to the subject of the page, which makes visually strong content unusually profitable for visibility in Microsoft Copilot.
The foundation of image SEO
Four things determine whether an image can be found, and they hold across every industry:
- The alt text describes what the image shows, for screen readers and search engines alike. It is the single most important signal, and the one most often skipped.
- The file name should say what the image is.

- The format and the weight decide whether the image even makes it onto the screen in time. WebP or AVIF at the right dimensions, compressed, with lazy loading on everything below the first viewport. This is where image work meets Core Web Vitals.
On top of that sit the technical supports that make the material unambiguous: an image sitemap so the crawler finds everything, and structured data for product, recipe and video content so the machines know what they are looking at.
Video follows the same logic, with one addition. A video is effectively invisible to the search engines if it only sits on the page as a player. The transcript, the captions, the title, the description and the video schema are what make the content readable, and what decide whether Google can pull out a key moment to show directly in the results. Audio and video that never gets transcribed is the most common unused asset we find at companies already producing plenty of material.
The guides in this section
- Visual search – how Google Lens and Pinterest Lens work, which industries gain most, and how to optimize image SEO from file format to sitemap.
- Alt tags – what an alt text should contain, how it differs from an image title, and why it serves accessibility and visibility at once.
- Video optimization – choosing a platform, title and description, thumbnail, transcription and video schema.
- Infographics – visual content that explains complicated relationships, earns links and gets reused across channels.
How to prioritize
Begin where you already have material. Most sites hold hundreds of images without alt text and dozens of videos without a transcript, and that gap can be closed without producing anything new. Then move on to the formats: if you sell something visual, your product images are your most important content, and if you explain something complicated, an infographic often beats another thousand words.
