What are Open Graph tags?

Open Graph (OG) tags are HTML meta tags that control how your page appears when shared on social media platforms like Facebook, LinkedIn, and Slack. They specify the title, description, image, and URL that appear in the social preview card.

What is the difference between OG tags and Twitter Cards?

OG tags (og:title, og:description, og:image) are used by Facebook, LinkedIn, and most platforms. Twitter Cards (twitter:card, twitter:title, twitter:image) are Twitter/X-specific. Twitter falls back to OG tags if no Twitter Card tags are present, but OG tags don't work in reverse.

What image size should I use for OG tags?

The recommended OG image size is 1200x630 pixels for Facebook and LinkedIn (1.91:1 ratio). For Twitter summary_large_image cards, use 1200x628 pixels. Always keep file size under 5MB for reliable rendering across platforms.

Why does my shared link show the wrong image or title?

Social platforms cache OG tag data. After updating your tags, use Facebook's Sharing Debugger, Twitter's Card Validator, or LinkedIn's Post Inspector to clear their cache. Also ensure your tags appear in the before any scripts load.

Is this Open Graph checker free?

Yes, completely free with no signup required. Enter any URL to instantly extract and preview all Open Graph and Twitter Card meta tags with social media previews.
