# 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 `` 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 `` for ``, ``, ``, and ``. 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 ``. 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.
## Code Review
Review metadata generation, rendered HTML, structured data, and response headers related to Add Twitter Card meta tags. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.
