Multimodal content checker

AI retrieval is text retrieval. Every image without alt text and every video without a transcript is work you did that machines cannot use.

Why it matters for AI search

Alt text is the only way an image enters a text index. A transcript is the only way a video’s content does. Media schema fills in what machines cannot extract on their own: what it shows, when it was made, where the thumbnail lives.

The rule matches accessibility, because the two align: informative media gets a text alternative, decorative images get an empty alt attribute, and neither is punished for being what it is.

What GetSlurp checks

This list comes straight from the audit engine, so it always matches what the extension and MCP server actually run.

media.alt-textGraded

Alt text is the only way image content enters text-based retrieval; images without it simply do not exist for AI answers.

Fix: Write descriptive alt text for every informative image.

media.video-transcriptGraded

Video content is invisible to text retrieval without a transcript or captions on the page.

Fix: Publish a transcript (or caption track) alongside embedded video.

media.schemaGraded

VideoObject/ImageObject schema gives machines the metadata (title, description, thumbnail) they cannot extract from the media itself.

Fix: Add VideoObject schema for embedded videos and ImageObject for key images.
