Live previewHow to Use This Social Card Tester
This free social media preview tool lets you test how your links will appear when shared on Twitter/X, LinkedIn, and Facebook. Simply enter your Open Graph (OG) meta tags above and see a real-time preview of your social cards.
Best Practices for Social Media Cards
- Image size: Use 1200×630 pixels for optimal display across all platforms. Minimum size is 600×315.
- Image format: PNG or JPG work best. Keep file size under 5MB for fast loading.
- Title length: Keep titles under 60 characters to avoid truncation on Twitter.
- Description length: Aim for 150-200 characters. Facebook shows up to 300, Twitter shows less.
- Text on images: Use large, high-contrast text. Many users browse on mobile.
Required Meta Tags for Social Sharing
Add these Open Graph tags to your page's <head> section:
<meta property="og:title" content="Your Title">
<meta property="og:description" content="Your description">
<meta property="og:image" content="https://yoursite.com/image.png">
<meta property="og:url" content="https://yoursite.com/page">
<meta name="twitter:card" content="summary_large_image">Frequently Asked Questions
Why isn't my social card showing the right image?
Social platforms cache your Open Graph data. After updating your meta tags, use each platform's cache clearing tool: Twitter Card Validator, Facebook Sharing Debugger, or LinkedIn Post Inspector.
What's the difference between OG tags and Twitter cards?
Open Graph (og:) tags are used by Facebook, LinkedIn, and most platforms. Twitter also reads OG tags but prefers its own twitter: tags when present. For best results, include both.
Do I need different images for each platform?
No, using one 1200×630 image works well across Twitter, Facebook, and LinkedIn. This tool previews how that single image will appear on each platform.
