Open Graph & Social Preview SEO Guide

OpenGraph Viewer is a free Open Graph and Twitter Card checker. Use it to preview links, find missing metadata, and fix social share cards before publishing.

What this social preview checker does

When a page is shared, platforms build a preview card from metadata in your HTML. This tool fetches public page tags and shows how that link is likely to render on Facebook, X, and LinkedIn.

How to use OpenGraph Viewer

  1. Paste a public URL in the checker above.
  2. Review preview cards for Facebook, X, and LinkedIn.
  3. Inspect missing tag warnings and full metadata values.
  4. Copy the generated source snippet to implement fixes faster.
  5. Re-test until your title, description, and image look right.

Most important Open Graph and Twitter tags

og:title

Main headline shown in Facebook and LinkedIn previews.

Tip: Keep it clear, specific, and close to your page title intent.

og:description

Summary text that helps people decide whether to click.

Tip: Write one concise sentence focused on value and relevance.

og:image

The most visual element in a shared card and key for engagement.

Tip: Use a high-quality 1.91:1 image with an absolute HTTPS URL.

og:url

Canonical share URL used to consolidate preview data.

Tip: Set this to your preferred canonical page URL.

twitter:card

Tells X which card format to render.

Tip: Use "summary_large_image" for most content pages.

Image guidance by platform

Facebook

1200×630

Use og:image. Keep important text centered to avoid crop issues.

X (Twitter)

1200×630

Works well with summary_large_image cards and large feed placements.

LinkedIn

1200×627 or 1200×630

LinkedIn reads Open Graph metadata, so og:image quality is critical.

Common preview issues and quick fixes

  • Preview shows the wrong title: make sure og:title is present and unique for the page.
  • Image is missing: confirm og:image uses an absolute HTTPS URL and is publicly reachable.
  • Old preview keeps showing: platform caches are stale, so trigger a re-scrape in each platform tool.
  • Wrong page URL appears: set og:url and rel=canonical to your preferred canonical URL.

FAQ

What tags are most important for social link previews?

Start with og:title, og:description, og:image, and og:url. In practice, og:type is also important, and most sites should include twitter:card plus Twitter title/image tags for stronger X previews.

Do Facebook, X, and LinkedIn use different metadata?

All three platforms read Open Graph tags, but X also uses Twitter Card tags when available. If both are present, X usually prefers twitter:* tags while Facebook and LinkedIn rely on og:* tags.

What image size should I use for preview cards?

A 1200×630 image (1.91:1 ratio) is a strong default across major platforms. X summary_large_image cards also work well with this ratio, and images should use absolute HTTPS URLs.

Why are my updated previews not showing immediately?

Social platforms cache link metadata. After updating tags, use each platform's re-scrape or inspector tools to refresh the cached preview, then test again.

Can this checker validate private or local URLs?

No. The checker fetches public pages over HTTP/HTTPS only. Localhost, internal hostnames, and private network IP ranges are blocked for security.
