Twitter Cards are a powerful way to make your tweets stand out with rich media previews. When someone shares your link on Twitter (now X), the card shows an image, title, and description. But what happens when your Twitter Card doesn't display? In this comprehensive guide, we'll walk you through all the common causes and solutions.
What Are Twitter Cards?
Twitter Cards are metadata tags that allow you to attach rich photos, videos, and media experiences to tweets that link to your content. There are four types:
- Summary Card - Title, description, thumbnail, and Twitter account
- Summary Card with Large Image - Similar to Summary but with a prominently featured image
- App Card - A card for mobile applications with direct download
- Player Card - For video/audio/media players
Why Twitter Cards Matter
Twitter Cards significantly impact engagement:
- Tweets with cards get 2x more engagement on average
- Rich media catches users' attention in busy feeds
- They provide context before users click
- They establish credibility and professionalism
Common Causes of Twitter Card Issues
1. Missing or Incorrect Meta Tags
The most common issue is missing or incorrectly formatted Twitter Card meta tags in your HTML head section.
2. Image Requirements Not Met
Twitter has strict image requirements. If your image doesn't meet them, the card won't display properly.
3. Twitter's Cache
Twitter caches card data. Even after fixing issues, old or broken cards may still appear until the cache refreshes.
4. robots.txt Blocking Twitter
If your robots.txt blocks Twitterbot, it can't crawl your page to generate the card.
5. SSL Certificate Issues
Twitter requires HTTPS. If your SSL certificate is invalid or your images are served over HTTP, cards may fail.
6. Server Response Problems
If your server is slow or returns errors, Twitter's crawler may timeout or receive incomplete data.
Step-by-Step Solutions
1. Add Required Twitter Card Meta Tags
Include these essential meta tags in your HTML <head>:
<head>
<!-- Essential Twitter Card Tags -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Your Page Title" />
<meta name="twitter:description" content="A brief description" />
<meta name="twitter:image" content="https://example.com/image.jpg" />
<!-- Optional but recommended -->
<meta name="twitter:site" content="@yourusername" />
<meta name="twitter:creator" content="@authorname" />
</head>2. Optimize Your Card Image
Follow Twitter's image guidelines:
- Summary Card: minimum 144x144 pixels, max 4096x4096
- Summary Large Image: minimum 300x157 pixels, max 4096x4096
- Aspect ratio: 2:1 for large image, 1:1 for summary
- Maximum file size: 5MB
- Supported formats: JPG, PNG, WEBP, GIF
- Use absolute URLs with HTTPS
3. Use the Twitter Card Validator
Twitter provides an official tool to test your cards:
- Go to cards-dev.twitter.com/validator
- Enter your URL and click 'Preview card'
- Check for any error messages
- The validator also forces a cache refresh
4. Allow Twitterbot in robots.txt
Make sure your robots.txt allows Twitter's crawler:
User-agent: Twitterbot
Allow: /
User-agent: *
Allow: /5. Verify SSL Certificate
Ensure your SSL is valid and all resources use HTTPS:
- Check certificate validity in browser (padlock icon)
- Ensure all image URLs use https://
- Test with SSL checker tools
- Update mixed content issues
6. Use Open Graph as Fallback
Twitter Cards will fall back to Open Graph tags if Twitter-specific tags are missing. Include both for maximum compatibility:
<head>
<!-- Open Graph (Facebook, LinkedIn, etc.) -->
<meta property="og:title" content="Your Title" />
<meta property="og:description" content="Your description" />
<meta property="og:image" content="https://example.com/image.jpg" />
<meta property="og:url" content="https://example.com/page" />
<!-- Twitter Card (overrides OG if present) -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Your Title" />
<meta name="twitter:description" content="Your description" />
<meta name="twitter:image" content="https://example.com/image.jpg" />
