Question 1

What Open Graph tags are required for Facebook sharing?

Accepted Answer

Facebook requires four Open Graph tags for a proper share preview: og:title (the title of your content), og:type (usually "website" or "article"), og:image (the thumbnail image URL — minimum 1200×630 pixels recommended), and og:url (the canonical URL of the page). Optional but highly recommended are og:description (a short summary) and og:site_name (your website name). Without these, Facebook will scrape your page and guess the preview content, often with poor results.

Question 2

What is the difference between Open Graph tags and Twitter Card tags?

Accepted Answer

Open Graph tags (og:title, og:description, og:image) are used by Facebook, LinkedIn, WhatsApp, Slack, and many other platforms. Twitter Card tags (twitter:card, twitter:title, twitter:description, twitter:image) are specific to X (formerly Twitter). Many platforms fall back to Open Graph tags if Twitter Card tags are missing, but it is best practice to include both. The main difference is the prefix: og: for Open Graph and twitter: for Twitter Cards.
