What Is Multimedia Content for SEO?
Multimedia content includes videos, images, audio files, and interactive elements that enhance your web pages. When properly optimized, multimedia improves user engagement, provides additional ranking opportunities, and can appear in specialized search features like video carousels, image results, and Google Discover.
The UXR SEO Analyzer evaluates your multimedia optimization to ensure videos, images, and other media are discoverable by search engines.

Video SEO Fundamentals
How Google Finds Videos
Google discovers videos through standard HTML elements:
<!-- Supported video embed methods -->
<video src="video.mp4" poster="thumbnail.jpg">
<track src="captions.vtt" kind="captions">
</video>
<iframe src="https://youtube.com/embed/VIDEO_ID"></iframe>
<embed src="video.swf" type="application/x-shockwave-flash">
Video Indexing Requirements

|---|---|
| Watch page | Dedicated page where video is primary content |
| Thumbnail | Valid image at stable URL |

| Accessibility | Video not behind login or robots.txt |
Watch Page vs. Embedded Video

<picture>
<source srcset="image.webp" type="image/webp">
