What is Facebook metadata?

Facebook metadata is a set of Open Graph tags that define how your link appears when shared: title, description, image, type, URL, site name, and locale. Correct tags improve CTR and brand consistency.

Rule of thumb
Use absolute URLs, return HTTP 200, and keep images fast to fetch. Avoid chained redirects and query-string randomness for OG images.

Essential OG tags

Core tags

Required for a good preview

<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="Concise description under ~200 chars." />
<meta property="og:image" content="https://cdn.example.com/og/slug-1200x630.jpg" />
<meta property="og:url" content="https://example.com/slug" />
<meta property="og:type" content="article" />

Optionally add og:site_name and og:locale.

Image requirements & CDN tips

Size & format

Reliable previews

  • 1200×630 (ratio ~1.91:1). PNG or JPEG, progressive JPEG is fine.
  • Keep under ~5 MB; avoid animated formats for link previews.
  • Use absolute URLs; ensure Cache-Control reasonable.

CDN & cache

Versioning

  • Version image filenames (slug-2025-09-23.jpg) to force refresh.
  • Avoid redirects to signed URLs where possible.
  • Return Content-Type: image/jpeg (or proper type).

Sharing Debugger & cache refresh

  1. Deploy updated tags/images.
  2. Open the Facebook Sharing Debugger, paste your URL, click Debug.
  3. If preview is stale, click Scrape Again.
  4. Purge CDN or wait for propagation if still cached.
Tip
Keep OG image URLs stable across minor content edits to leverage cache. Version only when the image changes.

Video, galleries & carousels

For video pages, use og:video with secure (https) MP4 or player URLs. Not all surfaces render video previews; always provide a static og:image fallback.

<meta property="og:video" content="https://cdn.example.com/video/clip.mp4" />
<meta property="og:video:type" content="video/mp4" />
<meta property="og:video:width" content="1280" />
<meta property="og:video:height" content="720" />

Dynamic OG images at the edge

Strategy

Templates + caching

Render title/brand into a template, cache by slug, and return an absolute CDN URL. Pre-generate for hot content.

Checklist

Production safety

  • TTFB < 300ms for OG endpoints.
  • Consistent font licensing and rendering.
  • Fallback to a static image on errors.

Locales & multi-language

Set og:locale (e.g., en_US) and maintain per-language titles/descriptions. Use canonical links and hreflang for search engines; OG uses the single selected locale for the preview.

Performance & validation

Validation

Quick checks

# Inspect head on a deployed URL
curl -s https://example.com/post | grep -Ei 'og:|twitter:|canonical' | sed -e 's/^/• /'
Use Sharing Debugger after deploy to verify card content and last scrape time.

Pre-publish checklist

Ship with confidence

  • Unique title/description per URL
  • Absolute image URL, 1200×630, 200 OK
  • No conflicting meta duplicates
  • CDN cache set; versioned filenames

Image privacy for social previews

OG images may originate from cameras or design exports and can carry hidden EXIF/GPS. Before committing them to your repo/CDN, scrub metadata to avoid leaking locations or device details.
