Understanding the Metrics
The visual thumbnail of your link. Facebook prefers high-resolution images (1200x630 pixels) with a 1.91:1 aspect ratio to display the large card format.
The bold headline and summary below the image. Keep titles under 60 characters and descriptions around 65-90 characters to avoid truncation on mobile apps.
og:url acts as the canonical link for aggregating likes and shares. og:type (like "article" or "website") tells Facebook how to categorize your content.
Optimization Guide
Key Concepts
- Open Graph Protocol: Originally created by Facebook to standardize how URLs are represented in the social graph.
- Fallback Behavior: If OG tags are missing, Facebook scrapes standard HTML
<title>and<meta name="description">tags, often leading to sub-optimal previews. - Cache Locking: Facebook heavily caches your tags. Updating your site won't immediately update Facebook's preview until the cache is cleared.
Best Practices
- Always define
og:urlto consolidate your Facebook sharing metrics and avoid duplicate URL issues. - Ensure your
og:imageuses an absolute HTTPS URL (e.g.,https://...) rather than a relative path. - Test major layout or header changes using this tool to ensure dev updates didn't accidentally remove your OG properties.
