Google Rich Results Test vs Schema.org Validator

Google Rich Results Test vs Schema.org Validator

Two validators, two different verdicts on the SAME markup. Here's why.

Rich Results Test
Pros:
— Tells you if the page is ELIGIBLE for a specific rich result (stars, FAQ, etc.)
— Reflects Google's actual current requirements, not the spec
Cons:
— Stays quiet about valid-but-unsupported types
— 'Eligible' ≠ 'will show'; it only means no disqualifying error

Schema.org Validator
Pros:
— Checks against the full spec, flags every malformed property
— Catches issues Google ignores but other engines/LLMs may not
Cons:
— 'Valid' here can still be ineligible for Google stars
— No opinion on rich-result eligibility

For: Rich Results Test when your goal is Google SERP features. Schema.org Validator when you want spec-clean markup for broad consumers (Bing, AI engines, voice).

Gotcha nobody mentions: A review page can pass Rich Results Test, show no errors, and STILL never get stars because self-serving review schema is policy-filtered, not error-filtered. The validator can't see policy.

Bottom line: Use both. Rich Results = 'can Google use it', Schema.org = 'is it correct'. Passing one isn't passing the other.
