Facebook created the Open Graph protocol in 2010 to standardize how external URLs render when shared across news feeds and Messenger. Today, Facebook processes billions of link shares daily, making Open Graph optimization essential for social traffic.

This guide details the exact tags, image requirements, and debugging tools needed for Facebook.


Required Facebook Open Graph Tags

Every page shared on Facebook must contain four mandatory Open Graph properties:

<meta property="og:title" content="Page Title Optimized for Social Sharing" />
<meta property="og:type" content="website" />
<meta property="og:url" content="https://example.com/page-url" />
<meta property="og:image" content="https://example.com/images/facebook-og.png" />
<meta property="og:description" content="A 150-character summary that hook users in the news feed." />
<meta property="og:site_name" content="Your Brand Name" />
<meta property="og:locale" content="en_US" />
<meta property="fb:app_id" content="1234567890" /> <!-- Optional: for Facebook Insights -->

Facebook Image Sizing & Aspect Ratios

To ensure your link previews display as full-width large images on both desktop and mobile feeds:

Specification Value
Recommended Dimensions 1200 × 630 pixels
Minimum Dimensions 600 × 315 pixels (for large cards)
Aspect Ratio 1.91:1
Max File Size 8 MB
Supported Formats JPEG, PNG

If your image is smaller than 600 × 315 pixels, Facebook will downgrade the card to a small square thumbnail.


Facebook Sharing Debugger

Facebook aggressively caches Open Graph metadata for performance. When you update your page’s OG tags, Facebook will not automatically fetch the new data until its cache expires.

How to Force Facebook to Scrape Fresh Tags:

  1. Navigate to the official Facebook Sharing Debugger.
  2. Enter your URL and click Debug.
  3. View the scraped metadata and preview card.
  4. Click Scrape Again to force Facebook’s servers to fetch the updated HTML tags.

High-CTR Facebook Preview Design Tips

  1. Bold Visual Contrast: Use images with strong focal points that stand out against Facebook’s white/dark background.
  2. Text Under 20%: Keep text overlays minimal on images to maximize visual clarity.
  3. Action-Oriented Description: Treat og:description as your copy prompt — encourage clicks by creating curiosity.
