What is a rich snippet?
A rich snippet is an expanded version of a normal Google search result: instead of just a title, URL and meta description, the listing adds visual elements that take up more space and show more information at a glance. A recipe card with a photo and cook time, a product with star ratings and price, or a breadcrumb path instead of the full URL are common examples.
The SEO industry coined the term more than a decade ago, and it's still what most people search for on Google. Google's own current documentation barely uses that word anymore: it officially talks about rich results. In practice both terms point to the same thing, the visual element that shows up when the markup is correct, and this glossary uses "rich snippet" because that's the name the industry actually searches for.
That markup is the page's structured data, almost always in JSON-LD format, and it's part of the regular work of technical SEO: checking that the code labels every content type correctly.
