Rich Results Test vs Schema.org Validator: pick by what's broken

Rich Results Test vs Schema.org Validator: pick by what's broken
Two validators, two jobs, and webmasters keep grabbing the wrong one. Google's Rich Results Test only tells you if a type is eligible for a Google feature — it stays silent on properties Google doesn't consume. The Schema.org Validator (validator.schema.org, the one that replaced the old Structured Data Testing Tool) checks the full spec, flagging invalid types and wrong value ranges Google ignores.
— Use Rich Results Test when you ask 'will this draw a rich result'
— Use Schema.org Validator when you ask 'is my markup actually valid'
— For AI/LLM consumption, lean Schema.org Validator: assistants read the whole graph, not just Google's eligible subset
What it means for you: validate twice. A green Rich Results Test with a broken sameAs array still poisons your entity graph. Watch this gap widen as AI search reads more of your markup than Google's feature set ever did.
