Review Schema and aggregateRating Schema are JSON-LD for marking up reviews for Google. In search, under your link appear stars (1-5), review count and a brief excerpt — a \"review rich result\". One of the most CTR-impactful schemas.
AggregateRating vs Review
AggregateRating — overall rating and review count. Review — an individual review with author, date, text, rating.
Best to use both. Google supports both, and the combination yields the best rich result.
AggregateRating
JSON-LD: ratingValue (1.0-5.0), bestRating, worstRating, ratingCount, reviewCount.
Review
A review array with Review objects: author, datePublished, reviewBody, reviewRating (ratingValue).

Inside Product, LocalBusiness, Restaurant, Movie, Book, SoftwareApplication, Service. Does not work for Article/BlogPosting.
Google rules
1. Reviews must be real. Bought reviews — penalty.
2. Visible on the page.
3. Author must be a real person or organisation.
Local Business
Stars in local results are critical for conversion. 4.8 + 200 reviews wins many more clicks than 3.2 + 5.
Maps
Google Maps prioritises 4.5+. Strategy: collect real reviews, reply to negatives professionally.
Movie/Book Schema
For film/book blogs — Movie/Book Schema + Review.
Review collection
Roundups (\"top 10 hostings\") — ItemList Schema + Product + Review for each.
Voice search
\"Hey Google, best hosting\" — Google uses AggregateRating to recommend.
