Validate your JSON-LD structured data against schema.org standards before search engines do. Paste code or enter a URL.
Structured data only helps when it is valid. A missing required property, a wrong data type, or a typo in a schema name makes the whole block unusable, and search engines simply ignore markup they cannot parse. Most schema problems are invisible until the rich result you hoped for never appears.
Validation catches these issues before they cost you. The checker reads your JSON LD, confirms it parses as valid JSON, verifies the schema types and properties exist in the Schema.org vocabulary, and checks data types and required fields. Each finding comes with the line that caused it, so the fix takes minutes, not hours.
This matters more as structured data grows in influence. Pages with clean, accurate markup give search systems consistent entity signals, which supports everything from rich results to knowledge panel connections. A validation step before publish keeps that pipeline clean.
Paste your JSON LD into the text area and click Validate. The tool parses the markup and runs it against the Schema.org vocabulary, then reports each error and warning with its location and a plain explanation.
Fix errors in priority order. A JSON parse error breaks everything, so resolve that first. Then address unknown types and properties, which usually mean typos. Finally, review warnings about recommended properties, because that is where rich result eligibility often lives.
Revalidate after every change until the report is clean. Once a page passes here, confirm it in Google Search Console with the URL inspection or Rich Results test. Valid markup plus verified indexing is the combination that actually earns enhanced results.
