Structured data checker lets you peek behind the scenes of a webpage to see how search engines interpret its content. I use it to validate schema markup on product pages, ensuring rich snippets like reviews and prices display correctly in search results. It's a handy tool for troubleshooting broken JSON-LD or missing properties that could hurt visibility.
