Free Open Graph Tag Checker

Open Graph tags control how your page looks when shared on Facebook, LinkedIn, Twitter/X, and Slack. A missing OG image, wrong title, or absent Twitter Card can turn a link share into a missed click. This tool checks all OG and Twitter meta tags and shows you a preview of how your page will appear when shared.

What This Tool Checks

og:title, og:description, og:image, og:url, og:type detection
Twitter Card: card type (summary/summary_large_image), twitter:title, twitter:image
Social sharing preview: shows how the link looks on Facebook/LinkedIn
OG image URL validation (checks if image is accessible)
og:url vs canonical URL alignment check
Missing tag detection with specific fix recommendations

Why This Matters for SEO

Open Graph tags don't directly affect Google rankings, but they control how your content appears when shared on social media — which drives significant referral traffic for many sites. A page without an OG image shows as a plain text link on Facebook and LinkedIn, getting far fewer clicks than a page with a compelling image preview. With social sharing increasingly important for content discovery, these tags are worth getting right.

Frequently Asked Questions

What are Open Graph tags?

Open Graph (OG) tags are meta tags in your page's <head> that control how your page appears when shared on social media platforms like Facebook, LinkedIn, Slack, and X/Twitter. They were created by Facebook and are now an open standard. The key OG tags are og:title (the headline), og:description (the summary), og:image (the preview image), and og:url (the canonical URL for the share).

What is the ideal OG image size?

Facebook and LinkedIn recommend 1200×630 pixels (roughly 1.91:1 aspect ratio) for og:image. Images smaller than 600px wide may not display at all. The file should be under 8MB. X/Twitter uses 2:1 ratio (1200×600px) for summary_large_image cards. Having a high-quality, purpose-designed OG image (not just your logo) significantly increases engagement when your content is shared.

Do I need both OG tags and Twitter Card tags?

Both are recommended for maximum compatibility. OG tags work on Facebook, LinkedIn, Slack, Discord, and many others. Twitter/X prefers its own twitter:card, twitter:title, and twitter:image tags, though it falls back to OG tags if Twitter tags are missing. For best results, include both sets of tags. The images and descriptions can be the same or customized per platform.
