A rich snippet is an enhanced search result that shows extra detail beyond the usual title and description, such as star ratings, prices, event dates, breadcrumbs or opening hours. Search engines build them from structured data on the page.
It is code added to a web page that describes its content in a form search engines and AI tools can read easily: this page is a product, this is its price, this is the business that sells it. It is usually written as JSON-LD using the schema.org vocabulary.
A warning means the markup is valid but is missing a property that Google recommends. Your page can still qualify for a rich result, but adding the property usually makes the result more complete and the markup more useful.
An error means something Google requires is missing or wrongly formatted, such as a price with a currency symbol or a date in the wrong format, so the markup is likely to be ignored. A warning means a recommended property is missing.
Valid markup makes a page eligible, but Google decides whether to show a rich result. It depends on the quality of the page and the search, and some types, such as a business’s own reviews of itself, are not shown at all.
