Review Schema
The schema.org Review and AggregateRating markup that makes star ratings and review counts machine-readable, subject to strict visibility and authenticity requirements.
What it means
Review schema lets a product page mark up individual reviews and an aggregate rating in a structured format search engines and AI platforms can parse and, in some cases, display directly. It's also one of the most misused schema types: markup must reflect ratings that are genuinely visible on the page and sourced from real reviews, search engines actively penalize aggregate ratings that aren't backed by visible, verifiable review content.
Why it matters for Shopify
Shopify merchants should only implement Review schema when the underlying ratings are genuinely visible and verifiable on the page, invisible or unsourced aggregate ratings risk being flagged as manipulative structured data.
