Review and AggregateRating structured data can produce the visible star rating snippets appearing directly in search results, a genuinely valuable, attention-grabbing rich result — but Google enforces strict, specific eligibility requirements around its use.
AggregateRating schema summarises a rating value and review count for an entity (typically a product, service or business), while Review schema can represent individual review content — both need to genuinely reflect real reviews visible on the actual page.
Marking up a rating that does not correspond to genuine, visible reviews, applying review schema to an entire category or organisation rather than the specific item actually being reviewed, or inflating the displayed rating relative to actual review data are all violations that can result in losing rich result eligibility, sometimes site-wide.
A star rating in search results is a powerful trust signal precisely because it usually reflects something genuine — misusing the schema to fake that signal is exactly the kind of shortcut Google actively polices.
Third-party review platforms, verified purchase reviews, or your own site's genuine customer review system (with real, verifiable submissions) are all legitimate sources — self-written testimonials without a genuine, verifiable review process do not meet Google's actual standard.
Google has specifically restricted self-serving organisation-level review schema in many cases — check current structured data guidelines carefully before implementing this specific use case.
Google can revoke rich result eligibility for the affected markup, and in more serious or repeated cases, this can extend to a broader loss of structured data rich result eligibility across the site.
There is no official minimum, but the reviews and rating displayed must genuinely, accurately reflect what actually exists and is visible on the page.

Only implement review schema for genuine, verifiable reviews you can actually display on the page — misuse is one of the more actively enforced structured data violations and can cost you rich result eligibility site-wide.
