See how your URL looks when shared on Twitter, Facebook, LinkedIn, and Slack
Open Graph tags control how your URL appears when shared on social media. Without them, platforms show a generic link instead of a rich preview with an image, title, and description.
At minimum: og:title, og:description, og:image, and og:url. For Twitter, also add twitter:card.
Add <meta property="og:title" content="Your Title"> tags in your HTML <head> section.
Use the SnapAPI metadata extraction endpoint to check OG tags for any URL via REST API. Free tier available.
