Search Engine - Rich Result (Rich Snippet)

A rich result is a rich result that is styled and contains graphical elements, including review stars, thumbnail images, or some kind of visual enhancement.

To display Rich Snippets, Search Engine looks for markup formats:

• Web Page Metadata - Json-Ld syntax
• microdata
• RDFa

Rich results with a more immersive experience are called enriched results, and feature advanced interaction capabilities.
