What types of rich results can structured data enable?
Structured data can enable FAQ accordions, recipe cards, product ratings, event listings, breadcrumbs, how-to steps, video carousels, and many other enhanced search result formats.
How do I test if my structured data is valid?
Use this tool to validate syntax and schema.org compliance. Google's Rich Results Test shows which rich result types your structured data qualifies for. Fix all errors before expecting rich results.
