Image Requirements and Best Practices

For best results, use 1200×630 images in JPG or PNG, under 5 MB, with strong contrast and clear subject matter. Keep crucial elements within a safe area so that cropping on mobile doesn’t hide key content. Avoid text-heavy images when possible; if text is needed, ensure it’s legible at small sizes.

  • Serve images over HTTPS with a stable URL that won’t change.
  • Provide absolute URLs for og:image.
  • Use descriptive file names and alt text in your CMS when available.
  • Host images on a fast CDN to minimize load time during scraping.

Common Errors Our Facebook Linter Catches

  • Missing og:title or og:description
  • Invalid or unreachable og:image URL
  • Non-HTTPS resources causing mixed content issues
  • Overly long titles or descriptions that truncate awkwardly

Technical Checklist for a Clean Facebook Preview

  • One set of Open Graph tags per page (avoid duplicates)
  • Canonical og:url that matches the final destination
  • Consistent og:site_name across your domain
  • Server returns 200 status for the URL and image assets
