Rich Snippet
Rich Search Result Snippet
Enhanced search results displaying additional information (ratings, prices, FAQs) extracted from structured data.
技术细节
Rich Snippet uses Schema.org vocabulary encoded as JSON-LD (recommended by Google), Microdata, or RDFa. It enables rich results in search: star ratings (Review), recipe cards (Recipe), FAQ accordions (FAQPage), how-to steps (HowTo), and breadcrumbs. Google validates structured data through the Rich Results Test. Invalid or spammy markup can result in manual actions. Structured data doesn't directly improve rankings but increases click-through rates by occupying more visual space in search results.
