Schema Markup Checker
Enter a URL to extract its JSON-LD and microdata structured data, with each JSON-LD block validated independently.
What this checks
This tool fetches the page and extracts every application/ld+json script block, parsing each one independently so a single malformed block never hides the others, plus a check for inline Microdata. This validates that the JSON itself is well-formed — it does not run Google's full Rich Results eligibility checks.
Frequently Asked Questions
- What structured data formats are checked?
- JSON-LD scripts and inline Microdata (itemscope/itemtype).
- Does valid schema guarantee a rich result?
- No — valid markup is necessary but doesn't guarantee any specific Google rich result; eligibility and display are at Google's discretion.
- How is this different from JSON-LD Extractor?
- This validates and summarizes schema types found; JSON-LD Extractor focuses on pulling out and displaying each raw block separately.
