Add Twitter Card meta tags
Pages shared on X without Twitter Cards show only a bare link; Cards add an image and description that significantly increase click-through rates from social traffic.
Quick Reference
- Add
<meta name="twitter:card" content="summary_large_image"> to enable rich previews when shared on X (Twitter)
- Minimum required tags:
twitter:card, twitter:title, twitter:description
- X falls back to Open Graph tags (
og:title, og:image) if Twitter-specific tags are absent
- Recommended image size for
summary_large_image: 1200×630 px, max 5 MB, JPG/PNG/WebP
Check
Inspect <head> for <meta name="twitter:card">, <meta name="twitter:title">, <meta name="twitter:description">, and <meta name="twitter:image">. Verify the card type is valid (summary or summary_large_image). Test the URL in the X Card Validator.
Fix
Add the required Twitter Card meta tags to the <head>. For article/blog pages use summary_large_image. Ensure twitter:image points to an absolute URL of an image at least 300×157 px (ideally 1200×630 px) under 5 MB.
Explain
Explain how Twitter Cards enhance shared links, the difference between summary and summary_large_image card types, and how X falls back to Open Graph tags.
