About this tool
AggregateRating triggers the star-rating display in Google search results. Generator outputs valid JSON-LD with ratingValue, reviewCount, bestRating and worstRating, drop into your Product, Service, Article or Recipe schema.
When AggregateRating triggers star results
- • reviewCount must be greater than 0 (real reviews, not aspirational)
- • ratingValue must be between worstRating and bestRating
- • Reviews must actually be displayed visibly on the page (Google penalises fake reviews)
- • Product reviews need to be FROM customers, not generic site testimonials
Frequently asked questions
What's the minimum to trigger SERP stars? +
reviewCount ≥ 1, ratingValue between worstRating and bestRating, and the AggregateRating must be embedded inside a parent type Google recognises (Product, LocalBusiness, Recipe, Course, SoftwareApplication, Movie, Book, Event).
Can I include AggregateRating on category pages? +
Not for stars in SERP, Google only awards rich result stars when AggregateRating is on a specific product page (Product type) or specific business (LocalBusiness). Site-wide ratings don't qualify.
Reviews must be from customers, not site testimonials, right? +
For Product star results, yes. Generic 'great service!' testimonials don't qualify. Google enforces this since 2019, fake or recycled reviews get a manual action that strips star eligibility site-wide.
What if I have under 10 reviews? +
Still mark them up, eligibility just requires reviewCount ≥ 1. SERP stars typically appear once you cross 5-10 real reviews and the product page is well-indexed. Single reviews are fine schema-wise but may not visually trigger the star result yet.
