What Are Twitter Cards?

Twitter (X) Card tags such as twitter:card, twitter:title and twitter:image control how links appear in posts. This tool reads a page's Twitter Card tags.

When to Use It

When links shared on X show no preview.
When setting up a new site's social metadata.

How to Use It

Enter the page URL.
Review the card type, title and image.

Understanding the Result

summary_large_image shows a large image and needs twitter:image (or og:image). X falls back to Open Graph tags when Twitter-specific tags are missing.

Limitations

Previews are cached by X. Check Open Graph tags with the Open Graph Checker.

A Complete Set of Tags

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="How to Check an SSL Certificate">
<meta name="twitter:description" content="What every field means, in plain English.">
<meta name="twitter:image" content="https://example.com/images/ssl-guide.jpg">
<meta name="twitter:image:alt" content="SSL certificate details for example.com">
<meta name="twitter:site" content="@yourbrand">

Card Types

Type	Looks like	Best for
`summary`	Small square thumbnail next to the text	Profiles, simple pages
`summary_large_image`	Wide image above the title	Articles, products, tools

Troubleshooting

No image: use an absolute https:// URL that is publicly reachable and not blocked by robots.txt.
Wrong image: X caches cards - changes can take time to show.
Image cropped: use a 2:1 or 1.91:1 image (such as 1200 × 630) for large cards.

Since X falls back to Open Graph tags, one good set of OG tags covers most platforms - check them with the Open Graph Checker and preview everything with the Meta Tags Preview.

Frequently Asked Questions

Not strictly required, since X/Twitter falls back to Open Graph data - but dedicated Twitter Card tags let you specify a different card layout (like "summary_large_image") and fine-tune exactly how the preview appears specifically on that platform.

It requests the large, prominent image preview layout rather than the smaller, compact thumbnail-style card - generally the more visually engaging and recommended choice for most content types.

Similar to other platforms, X caches preview data per URL - if you've recently changed the tags, the platform's own card validation/preview tool typically offers a way to force it to re-fetch the current version.

Reusing the same image referenced by your og:image tag is completely standard and works fine - a separate twitter:image is only needed if you specifically want a different image tailored to that platform.

No direct ranking effect - their value is entirely in how your content appears when shared on that platform, which can indirectly drive more referral traffic and engagement rather than affecting search rankings themselves.
