Why Structured Data Matters

Structured data helps search engines understand your content and display rich snippets in search results. JSON-LD, Microdata, Open Graph, and Twitter Cards each serve a different purpose — from Google rich results to social media previews. Proper schema markup can improve click-through rates by up to 30%.

What We Check

• JSON-LD — Google's recommended format for structured data. We parse and validate all JSON-LD blocks against schema.org vocabulary.
• Microdata — HTML-embedded structured data using itemscope/itemprop attributes. Detected and validated automatically.
• Open Graph — Meta tags for social media previews on Facebook, LinkedIn, Telegram and other platforms.
• Twitter Cards — Meta tags for rich link previews on X (Twitter). Summary, large image, player and app card types.
