MetaShield

Open Graph Checker

Check your Open Graph tags and see how your links appear on Facebook, LinkedIn, Slack, Discord, and more.

What are Open Graph tags?

Open Graph (OG) tags are meta tags that control how your links appear when shared on social platforms. Originally created by Facebook, they are now used by LinkedIn, Slack, Discord, WhatsApp, Telegram, and many other apps. The most important tags are og:title, og:description, and og:image — these determine the preview card people see when your link is shared.

Why check your Open Graph tags?

Broken or missing OG tags mean your links look bare when shared — no image, wrong title, or a generic description. This hurts click-through rates and makes your content look unprofessional. Common issues include missing og:image tags, images that are too small (should be 1200x630px), titles that get truncated, and duplicate or conflicting tags. Checking before you share ensures your content looks great everywhere.

What does MetaShield check?

MetaShield validates all Open Graph tags including og:title, og:description, og:image, og:type, og:url, and og:site_name. It also checks Twitter Card tags, basic SEO meta tags (title, description, canonical URL), technical tags (charset, viewport, robots), and JSON-LD structured data. You get a scored report out of 100, platform previews for 6 platforms, and copy-paste HTML fixes for every issue found.

What is the ideal og:image size?

The recommended og:image size is 1200 x 630 pixels with a 1.91:1 aspect ratio. This size works well across Facebook, LinkedIn, Slack, and Discord. Images smaller than 600x315px may not display as a large preview card on some platforms. Always use absolute URLs for og:image (starting with https://) and ensure the image file is under 8MB.
