Rich results — star ratings, FAQ dropdowns, product pricing, breadcrumbs — depend on
JSON-LD structured data being present, valid, and complete on the page.
Separately, how a link looks when shared on Facebook, LinkedIn, Slack, or X depends on that
page's Open Graph and Twitter Card meta tags. Most pages are missing one or
both. This tool covers both halves: the Generate tab builds valid JSON-LD and
the matching social meta tags for common types (Article, Product, Local Business, FAQ,
Organization, Review, Breadcrumb) from a simple form, with a live Google-result and
social-card preview as you type. The Validate tab does a real, timed fetch of
any live URL you give it, parses its actual <script type="application/ld+json">
blocks with a real JSON parser, and checks each detected type against the fields Google
generally expects for rich-result eligibility — then reads the page's real Open Graph and
Twitter tags the same way.
Both halves read the page as delivered in its raw HTML — tags injected purely by client-side JavaScript after the page loads won't be visible to the validator, the same limitation any non-browser-based checker has. Field requirements here are a practical, commonly-used subset for the most popular types, not a full mirror of schema.org's spec — always confirm anything ranking-critical in Google's own Rich Results Test before shipping.
