Données structurées (schema)
Machine-readable labels that unlock rich results and make you quotable. Affecte: SEO + AIO
Speaking the machines' language
Schema.org JSON-LD is a small block of code that states facts machines can trust: who operates the site (Organization), what a page is (Article, Product, FAQPage, LocalBusiness), prices, ratings, dates, addresses. Search engines use it for rich results (stars, FAQs, sitelinks, knowledge panels), and answer engines use it to extract facts with confidence.
Open Graph tags do the same job for social sharing: they control the title, description and image your links show in messages and feeds.
What this site measures
Valid JSON-LD presence and the types found, an identity type (Organization or WebSite), Open Graph completeness (title, description, image), a Twitter/X card, and a favicon. Every review lists the exact types our crawler parsed.
How to improve
- Start with Organization + WebSite schema on the homepage: name, logo, links.
- Add the type that matches each page: Article, Product, FAQPage, LocalBusiness.
- Schema must describe visible content; invisible-only markup violates guidelines.
- Validate with the free schema.org validator and Google's Rich Results test.
- Add og:title, og:description and a 1200×630 og:image sitewide.
Common mistakes
JSON-LD with syntax errors (one missing comma disables the whole block). Review stars marked up without visible reviews. Og:image missing, so shared links show blank gray cards.
