📖 About Metadata Extraction

Metadata is the foundation of on-page SEO. Search engines, social platforms, and other services rely on metadata to understand, categorize, and display your content. This tool extracts and analyzes all metadata from any webpage to help you audit and optimize your SEO.

⚖️ This tool extracts publicly available metadata for SEO analysis purposes. We respect robots.txt and rate limits. Content remains property of original owners.

🎯 Types of Metadata

  • Basic SEO: Title, description, keywords, robots directives, author
  • Open Graph: Facebook/LinkedIn sharing data (title, description, image, type)
  • Twitter Cards: Twitter-specific sharing format (summary, large image, app, player)
  • Technical: Canonical URLs, viewport, charset, language, hreflang
  • Schema: Structured data for rich snippets (Article, Product, Event, etc.)
  • HTTP Headers: Content-Type, X-Robots-Tag, Link headers

❓ Frequently Asked Questions

Why can't I extract from some URLs directly?

Due to browser security restrictions (CORS), we cannot fetch URLs directly from client-side JavaScript. However, you can:

  • Paste the HTML source code directly (right-click → View Page Source, Ctrl+U)
  • Upload an HTML file from your computer
  • Use our sample HTML for testing

For production use, consider implementing a server-side proxy.

What's the difference between meta tags and Open Graph?

Standard meta tags (title, description) are used by search engines like Google, Bing, and Yahoo. They help with SEO and search result display.

Open Graph tags (og:title, og:description, og:image) are used by social platforms like Facebook, LinkedIn, and Pinterest to format shared content. They control how your page appears when shared on social media.

You need both for complete SEO and social media optimization.

How do I fix missing metadata?

To fix missing metadata:

  1. Use our Meta Tag Generator to create proper tags
  2. Add them to your page's <head> section
  3. For CMS platforms like WordPress, use SEO plugins (Yoast, Rank Math, All in One SEO)
  4. For Open Graph images, ensure you have a social media image (1200×630px)
  5. Test with our preview tabs to verify appearance
What is schema markup and why do I need it?

Schema markup (JSON-LD) is structured data that helps search engines understand your content better. It enables rich snippets in search results like:

  • ⭐ Star ratings for reviews
  • 💰 Prices for products
  • 📅 Dates for events
  • 👤 Author information for articles
  • 🍔 Menu items for restaurants

Pages with schema markup rank better and have higher CTR (click-through rates).
