What does the tool do?
Build supported JSON-LD types and validate syntax, expected fields, URLs, and entity consistency.
Structured data
Schema Checker
Validate JSON-LD markup from a URL or pasted code block, then see what search engines can understand.
Why it matters
Clean schema helps Google understand page type, brand, product, service, FAQ, and navigation context.
SEO note
Connect Schema Checker output to search visibility.
A tool result is not the final report by itself; it should be read together with technical signals, page intent, and competition level.
01
Read technical SEO signals in one place and prioritize the next action.
02
See more clearly how search engines crawl and interpret the page.
03
Connect the output to content, performance, and security improvements.
Interpret the tool correctly
Method, data, and limitations
How does it work?
Choose a supported type to generate JSON-LD or paste JSON-LD for deterministic validation.
What data is analyzed?
Only the form values or pasted JSON-LD submitted for the current request.
How should results be interpreted?
Fix invalid JSON, missing expected fields, bad URLs, and conflicting @id entities before publishing.
Limitations
- — Validation does not guarantee a rich result.
- — Search engines may impose additional eligibility rules.
- — The validator does not publish markup to your website.
Privacy and data retention
- — Validation runs entirely on our server for the duration of the request.
- — The JSON-LD you paste is never stored; only the tool key, the detected @type list, and issue keys are recorded.
- — No form field you fill in is persisted with the run.
- — Your IP address is stored only as an irreversible hash for abuse protection.
- — Results are not published, are not indexed, and never appear in our XML sitemap.
