## Definition

The Rich Results Test is Google's free tool for validating structured data markup and previewing how a page may appear as a rich result in Google Search. It identifies schema markup errors, warnings, and eligibility for specific rich result types.

## Why It Matters for AI Search

The Rich Results Test is the [structured data](https://www.platelunchcollective.com/services/entity-seo) audit starting point. Before structured data can contribute to AI citation, it must be correctly implemented and error-free. Running key pages through the Rich Results Test identifies implementation errors that would prevent schema from being processed — including common issues like missing required properties, incorrect types, and inaccessible markup.
