## Why it matters

Pages with structured data can earn rich snippets in results (star ratings, prices, recipes, events). These enhancements increase visibility and CTR by up to 30%.

## In practice

Amazon uses Product schema on every product, allowing Google to display price, availability, and ratings directly in results. Recipe sites like AllRecipes use Recipe schema to show preparation time and ratings.

## How be1st checks it

Checks for the presence of structured data in JSON-LD or microdata format (Schema.org). Structured data helps search engines understand page content more precisely and display rich snippets.
