Validator.schema.org vs Rich Results Test — not the same
| Tool | What it validates | When to use |
|---|---|---|
| validator.schema.org | Schema.org specification compliance — correct types, required properties, enum values | Always — primary validation |
| Rich Results Test | Whether Google can generate a rich result from this page's schema | After schema is spec-valid, to check Google eligibility |
| GSC > Enhancements | Errors Google encounters on crawled pages at scale | Production monitoring |
