Twitter Cards
Meta tags similar to Open Graph but specifically for enhancing links shared on X (formerly Twitter).
Detailed Explanation
Twitter cards allow you to attach rich media (images, videos) to tweets. The most common is the `summary_large_image` card. While many platforms support Open Graph as a fallback, explicitly defining Twitter tags ensures your content looks exactly as intended in the X feed, maximizing your social reach.
Quick Summary
Twitter Cards are meta tags (`twitter:card`, `twitter:title`, etc.) that control how your link looks on X. The most common type is `summary_large_image`, a big banner card with image, title, description. X falls back to Open Graph when Twitter tags are missing, but defining both removes ambiguity.
Key Takeaways
- Four card types: `summary`, `summary_large_image`, `app`, `player`.
- `summary_large_image` is the standard choice, visually dominant in the feed.
- Image: minimum 300x157px, recommended 1200x675px (16:9 ratio).
- `twitter:site` and `twitter:creator` add author attribution.
- Test with X's Card Validator tool before launching.
When to use it
- Promoting blog posts, products, and announcements on X.
- Driving traffic from tweets with high-contrast preview images.
- Establishing brand consistency across all social shares.
- Maximizing engagement on link-share tweets (cards get more clicks than plain URLs).
Common Mistakes
- Defining only Twitter Cards and skipping Open Graph, fails on every other platform.
- Image ratio mismatch, non-16:9 images get cropped weirdly.
- Forgetting `twitter:card` declaration, without it, the rest is ignored.
- Using local file paths instead of absolute URLs.
Twitter Cards, Frequently Asked
Is `summary` or `summary_large_image` better?
`summary_large_image` almost always, it takes more feed space and drives higher CTR.
Do I still need Twitter Cards if I have Open Graph?
X uses OG as fallback, but explicit Twitter tags give you per-platform control (e.g., different title for X vs LinkedIn).
Why doesn't my card show up?
First share triggers a crawl, use X's Card Validator to force it. Check that your image URL is publicly accessible.
