Always add reviewCount to demonstrate authenticity and credibility.
Update Regularly
Keep ratings current as new reviews are submitted to maintain accuracy.

Never show ratings to search engines while hiding them from actual users.

Common Questions
How long until ratings appear in search results?
Typically 1-2 weeks after implementation, though Google doesn't guarantee rich snippets will display. Display depends on content quality, relevance, and various algorithmic factors.
Do I need a minimum number of reviews?
While there's no strict minimum, having at least 5-10 reviews adds credibility. Higher review counts increase the likelihood of rich snippet display.
Can I add ratings without individual reviews?
Yes, you can include just the aggregateRating. However, adding sample reviews increases chances of display and provides more context to users and search engines.
