What Is Open Graph and Why It Matters

Open Graph (OG) is a markup protocol developed by Facebook (Meta) that lets you control how your page appears when shared on social media and messengers. OG tags define the title, description, image, and content type for link previews.

What This Tool Checks

  • og:title — title displayed on social media
  • og:description — page description for the preview
  • og:image — image for the link card
  • og:url — canonical page URL
  • og:type — content type (website, article, etc.)

Why Open Graph Is Important

When a user shares a link on Facebook, LinkedIn, WhatsApp, or other platforms, the platform automatically generates a preview card based on OG tags. Without them, the preview may be missing entirely or contain irrelevant information — random text from the page or an unsuitable image.

  • An attractive preview card increases link click-through rate
  • Control over how content appears on Facebook, LinkedIn, X (Twitter), WhatsApp
  • Improves brand recognition when content is shared
  • Indirectly affects SEO through increased social media traffic

Common Mistakes

  • Missing OG tags — social platforms generate previews automatically, often incorrectly
  • No og:image — cards without images attract significantly less attention
  • Image too small — minimum 1200x630 pixels recommended
  • og:title and og:description match title and description — missed opportunity to adapt text for social media
  • Relative URL in og:image — image won't load on external platforms

Frequently Asked Questions

Which OG tags are required? ▶
Minimum set: og:title, og:description, og:image, and og:url. Without them, most platforms can't build a proper preview card. It's also recommended to include og:type (usually "website" or "article").
Should OG tags differ from regular title and description? ▶
Not necessarily, but it's recommended. Title and description are optimized for search results, while OG tags are for social media. On social platforms, you can use a more informal tone, calls to action, or emotional headlines that work better in feeds.
What image size is needed for og:image? ▶
Recommended size is 1200x630 pixels (1.91:1 aspect ratio). Minimum size for most platforms is 600x315 pixels. Facebook and LinkedIn display images well at this aspect ratio. Format: JPG or PNG, file size up to 5 MB.
