Why Open Graph Tags Matter
When someone shares your URL on Facebook, LinkedIn, Slack, or any other platform, Open Graph tags control what appears in the preview card. Without them, platforms guess — often picking the wrong image, a truncated title, or no description at all. A well-configured OG setup can significantly increase click-through rates from social shares.
What Are Open Graph Tags?
Open Graph is a protocol created by Facebook that lets you control how your content is represented when shared on social platforms. The essential tags are:
- og:title — The title shown in the share card
- og:description — A short summary below the title
- og:image — The preview image (recommended: 1200×630px)
- og:type — The content type (website, article, product, etc.)
- og:url — The canonical URL for the shared page
Twitter Card Tags
Twitter (X) uses its own meta tags (twitter:card, twitter:title, twitter:description, twitter:image) but falls back to Open Graph tags when Twitter-specific ones are missing. Setting both ensures consistent previews across all platforms.
Best Practices
- Use images at least 1200×630 pixels for high-quality previews on all platforms.
- Write unique og:title and og:description for each page — don't reuse the same tags site-wide.
- Set both Open Graph and Twitter Card tags for maximum compatibility.
- Always test your tags after deploying changes — platforms cache previews aggressively.
Common Mistakes
- No og:image set — platforms show a blank or random image from your page.
- Image too small — Facebook requires at least 200×200px; under 600px wide it shows a small thumbnail instead of a large card.
- Missing og:title — the platform falls back to the HTML <title>, which may be too long or include site name suffixes.
- Same OG tags on every page — sharing different pages produces identical-looking cards, confusing users.
