About This Twitter/X Checker
Twitter Cards transform plain links shared on Twitter/X into rich media previews with images, titles, and descriptions. Without proper Twitter Card meta tags, your shared links appear as bare URLs — missing the visual engagement that drives clicks and retweets in a fast-scrolling feed.
Unlike Facebook's Open Graph system, Twitter has its own separate meta tag specification using the twitter: prefix. While Twitter falls back to OG tags when Twitter-specific tags are missing, relying on this fallback often produces suboptimal results — the wrong image size, truncated descriptions, or a small summary card when a large image card would perform better.
A Twitter Card checker validates your twitter: tags and previews exactly how your link will render in the Twitter/X feed. With Twitter's timeline moving fast and attention spans short, a visually compelling card preview can be the difference between a link that gets engaged with and one that gets scrolled past.
Twitter Cards vs Open Graph: Key Differences
Twitter uses its own meta tag system (twitter:card, twitter:title, twitter:description, twitter:image) rather than OG tags, though it falls back to OG equivalents when Twitter-specific tags aren't present. The critical difference is the twitter:card type — choosing between summary, summary_large_image, app, and player cards determines the entire visual format of your preview.
The summary_large_image card type is what most websites want — a large banner-style image above the title and description. The standard summary card shows a small square thumbnail to the left of text. Choosing the wrong card type is one of the most common Twitter Card mistakes, resulting in smaller, less engaging previews than intended.
Twitter also enforces stricter image requirements than Facebook in some ways. The twitter:image must pass Twitter's image validation — certain image formats, dimensions, or hosting configurations can cause the image to fail to load in Twitter's card preview even when it displays fine elsewhere.
Key Considerations for Twitter/X
Card Type Selection
The twitter:card type determines your entire preview format. Use 'summary_large_image' for content with compelling visuals (blog posts, products, landing pages). Use 'summary' for text-focused content. The wrong card type significantly reduces visual impact and click-through rates.
Image Requirements for Large Cards
For summary_large_image, Twitter recommends images of at least 1200x628px with a 1.91:1 aspect ratio — the same as Facebook OG images. Images must be under 5MB and in JPG, PNG, WEBP, or GIF format. Animated GIFs are supported for the image preview.
twitter:site and twitter:creator
Always include twitter:site (your brand's Twitter @handle) and twitter:creator (the content author's @handle) tags. These add credibility to your cards and make it easy for readers to follow you directly from the preview. They're optional but significantly boost engagement.
Twitter Card Approval
Previously, Twitter required manual card approval for new domains. This requirement was removed, but Twitter's validator must still be able to fetch your page and image. Ensure your page isn't blocked by robots.txt for Twitter's crawler (Twitterbot) and that images are publicly accessible.
Common Twitter/X Issues
Card Type Problems
- •Using 'summary' card type when 'summary_large_image' would be more impactful
- •Missing twitter:card tag entirely, causing Twitter to fall back to a minimal preview
- •App card or player card type used incorrectly for standard web content
- •Card type not matching the content — large image cards for text-only pages
Image Issues
- •Image too small for summary_large_image — displays as small thumbnail instead
- •Image blocked by Twitterbot in robots.txt preventing card image loading
- •Image URL using HTTP instead of HTTPS — Twitter requires secure image URLs
- •Image file too large (over 5MB) causing card to render without image
Tag Configuration
- •twitter:title missing, falling back to og:title which may be formatted differently
- •twitter:description too long — Twitter truncates at around 200 characters
- •Missing twitter:site tag reducing card credibility and discoverability
- •Incorrect @handle format in twitter:site (must include the @ symbol)
How to Fix Twitter/X Issues
Complete Twitter Card Tag Setup
Include all recommended Twitter Card tags alongside your OG tags:
<head>
<!-- Twitter Card tags -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@YourBrandHandle" />
<meta name="twitter:creator" content="@AuthorHandle" />
<meta name="twitter:title" content="Your Page Title – Under 70 Characters" />
<meta name="twitter:description" content="Compelling description under 200 characters for Twitter feed." />
<meta name="twitter:image" content="https://yourdomain.com/twitter-card.jpg" />
<meta name="twitter:image:alt" content="Descriptive alt text for accessibility" />
<!-- OG tags as fallback (Twitter reads these if twitter: tags missing) -->
<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="Your description" />
<meta property="og:image" content="https://yourdomain.com/og-image.jpg" />
</head>Next.js 15 Twitter Card Metadata
Use Next.js metadata API to generate Twitter Card tags alongside OG tags:
// app/your-page/page.tsx
export const metadata = {
twitter: {
card: "summary_large_image",
site: "@YourBrandHandle",
creator: "@AuthorHandle",
title: "Your Page Title",
description: "Twitter-optimized description under 200 characters.",
images: [
{
url: "https://yourdomain.com/twitter-card.jpg",
alt: "Descriptive alt text",
},
],
},
// Always include OG as fallback
openGraph: {
title: "Your Page Title",
description: "Your description",
images: ["https://yourdomain.com/og-image.jpg"],
},
};Allow Twitterbot in robots.txt
Ensure Twitter's crawler can access your pages and images:
# robots.txt — allow Twitterbot explicitly
User-agent: Twitterbot
Allow: /
# If you block all bots, whitelist Twitterbot specifically
User-agent: *
Disallow: /private/
User-agent: Twitterbot
Allow: / # Override the block for Twitter's crawlerCommon Use Cases
- Validating Twitter Cards before a product launch or campaign
- Debugging why Twitter shows small thumbnails instead of large cards
- Testing card previews for blog content and articles
- Verifying @handle tags appear correctly in card attribution
- Checking image accessibility with alt text validation
Pro Tip
Create a single 1200x628px image that works for both Facebook OG and Twitter summary_large_image cards — they use virtually identical dimensions. This lets you maintain one image per page rather than platform-specific variants, simplifying your content workflow significantly.
