What Is a Schema Markup Validator?

The Schema Markup Validator extracts application/ld+json from your page or parses pasted JSON-LD, then checks required and recommended fields for popular types: Article/BlogPosting, Product, FAQPage, HowTo, BreadcrumbList, Organization, and LocalBusiness. It highlights errors that can block eligibility for rich results and warns about best-practice gaps.

What This Tool Checks

Structure: @type, @context, @id
Required fields per type (e.g., headline for Article, offers for Product)
Recommended fields that improve eligibility (e.g., image, aggregateRating)
URLs: absolute vs relative, and whether they look valid

Tips for Better Rich Results

Ensure every item has the correct @type and required properties.
Use absolute URLs for url and image values.
Keep dates in ISO 8601 (YYYY-MM-DD or with time).
Match Product price & availability to what’s on the page.

Pro tip: JSON-LD is preferred over microdata because it’s easier to maintain and less fragile during template changes.
