If product reviews don’t appear, it may be due to schema markup errors, unapproved formats, or missing required fields.

For product reviews to show in search results, schema markup must be correct and validated by Google. Review structured data guidelines and use Google’s Rich Results Test to ensure your reviews meet the criteria. Ensure all necessary fields—review rating, author, and date—are present. Google only approves certain formats, so confirm that your setup complies with its specifications. Addressing schema errors and adhering to guidelines maximizes the chance of reviews appearing in search results, attracting more clicks.
