Schema Markup Validator

Paste your JSON-LD (or a full page's HTML) and catch missing fields before Google does.

Paste your structured data

Works with output from the Schema Markup Generator, or anything you paste from your own site. Multiple JSON-LD blocks in pasted HTML are all checked separately.

This checks structure and common field requirements, not full schema.org compliance. It covers Organization, FAQPage, Article (and NewsArticle/BlogPosting), and Product in depth. Other types are checked for valid JSON-LD syntax only. For an authoritative eligibility check against live Google features, use Google's own Rich Results Test as well.

Schema drifts out of date quietly

A template change or a CMS update can silently break your structured data months before anyone notices. Weeklift's weekly digest surfaces pages with issues alongside your real ranking and click data.
