Validation tips

Follow Google review snippet policies for self-serving reviews
Reviews must be visible on the page
AggregateRating requires multiple ratings meeting thresholds

Overview

Review markup is high risk if it looks manipulative. Prefer AggregateRating when you have many genuine ratings that meet visibility requirements.

When in doubt, ship Product + Offer first; add reviews after legal/marketing review.
