Rich snippet explained without jargon.

Context and application

Google doesn’t guarantee rich snippet even with valid schema — the algorithm evaluates quality, trust, relevance. New sites may not receive rich snippets for months even with perfect implementation. To maximize chances: 100% validation in Rich Results Test, high content quality, no spammy patterns. On E-commerce, Product schema with price + availability + aggregateRating can turn the plain snippet into a mini-card with price + stars + stock — measurable CTR difference.
