FIX
No Open Graph tags found — social sharing previews will be generic.
Warning::
No Open Graph meta tags found
Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

Why this matters

Without Open Graph tags, social shares show a broken or empty preview card.

Learn more ▾

When someone shares your URL on Facebook, LinkedIn, Slack, iMessage, or any modern chat app, the preview comes from <meta property="og:*"> tags. Without them you get either no card or whatever fragment the social platform guesses — usually unflattering. The four core og: tags (title, description, image, url) cover what every major platform actually reads.
