Common Mistakes
- Missing Twitter Card tags (Twitter won't display images properly without them)
- Using relative image URLs instead of absolute https://
- Images too small or wrong aspect ratio
- Title/description too long (gets truncated)
Implementation
Next.js (App Router)
export const metadata = {
twitter: {
card: 'summary_large_image',
title: '...',
description: '...',
images: ['https://example.com/twitter.jpg'],
site: '@yourusername',
creator: '@authorusername',
},
};
HTML (generic)
<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">
<meta name="twitter:site" content="@yourusername">
<meta name="twitter:image:alt" content="Alt text">
