Lesson 10 of 28 · Structured data
Keep review markup honest
What it is
Review and rating schema can show stars, but only for reviews collected and shown on your own site.
Why it matters
Faked or copied review markup can get your site penalised and makes AI tools trust the rest of your data less.
✓ Good example
A testimonials page with real customer reviews, marked up with who wrote them and the date.
✗ Common mistake
Hard-coding '5 stars from 900 reviews' into every page's schema.
You pass when: Only first-party reviews shown on the page are marked up.
