Frequently Asked Questions

What are Open Graph tags?▾

Open Graph (OG) tags are HTML meta tags that control how URLs appear when shared on social media platforms like Facebook, LinkedIn, Twitter/X, Slack, and Discord. Developed by Facebook in 2010, OG protocol is now the standard for link previews across the web. Key tags: og:title (headline), og:description (summary), og:image (thumbnail), og:url (canonical URL). Without OG tags, platforms guess the content — often poorly. With proper OG tags, you control exactly how your content looks when shared, dramatically improving click-through rates.

What is the difference between Open Graph and Twitter Cards?▾

Open Graph is the general standard used by Facebook, LinkedIn, Slack, Discord, and most platforms. Twitter Cards are Twitter/X-specific meta tags (twitter:card, twitter:title, twitter:description, twitter:image). Most implementations need both. Good news: if Twitter-specific tags are absent, Twitter falls back to OG tags. Recommended: set both for maximum compatibility. Twitter card types: summary (small image), summary_large_image (full-width banner — most common), app (mobile app), player (video). The summary_large_image type with a 1200×628px image creates the most eye-catching previews.

What is the ideal image size for Open Graph?▾

Recommended OG image size: 1200×630px (1.91:1 ratio). Minimum: 600×315px. Maximum file size: under 8MB (Facebook limit), ideally under 1MB for fast loading. Facebook will crop images that don't meet the ratio. LinkedIn prefers 1200×627px. Twitter/X summary_large_image: 1200×675px (16:9 ratio). Always use absolute URLs for og:image (including https://). Use JPG or PNG format. Include alt text via og:image:alt for accessibility. Pro tip: include your brand/logo in the image since it appears without context in social feeds.

How do I validate my Open Graph tags?▾

Testing tools: Facebook Sharing Debugger (developers.facebook.com/tools/debug) — paste your URL, scrapes and shows preview + errors. LinkedIn Post Inspector (linkedin.com/post-inspector) — same for LinkedIn. Twitter Card Validator (cards-dev.twitter.com/validator) — for Twitter cards. Note: Facebook and LinkedIn cache previews aggressively. After fixing tags, use the debugger's "Scrape Again" button to force refresh the cache. Common issues: missing og:image (no preview shown), image too small (ignored), relative image URLs (not supported), missing og:title fallback to page title.

What is og:type and when should I use different values?▾

og:type tells platforms what kind of content the page is. Most common values: website (default — homepage or general pages). article (blog posts, news articles — enables article:published_time, article:author). product (e-commerce items — enables og:price:amount). video.movie / video.episode (video content). music.song / music.album (audio content). For articles: add article:published_time (ISO 8601 date), article:author (URL of author page), article:section (category), article:tag (keywords). For most sites, website and article cover 99% of use cases.
