Rich snippet
A rich snippet augments a standard search result with visual elements drawn from structured data: review stars, price, availability, thumbnails. It attracts attention and improves click-through rate at the same ranking position.
In practice
Markup is a candidacy, not a guarantee: Google decides case by case and withdraws enhanced displays when they are abused — self-attributed review stars have been cleaned up in several algorithm waves. Formats still productive in 2026: products, reviews, events, recipes. FAQ rich results have lost enhanced display for nearly all sites.
