What are Social Media Cards?

Social media cards are the rich snippets that appear when a URL is shared on social platforms. Unlike plain text links, these cards display a preview image, title, and description, making your content significantly more attractive and engaging in a user's feed.

Key Benefits

Higher Click-Through Rates (CTR): Rich media snippets can increase clicks by up to 40%.
Brand Professionalism: Consistent branding across platforms builds trust.
Control: You decide exactly which image and text represent your content, rather than letting the platform guess.

Supported Protocols

1. Open Graph Protocol (OG)

Originally created by Facebook, Open Graph is now the universal standard for link previews. It is supported by Facebook, LinkedIn, Pinterest, Discord, Slack, and WhatsApp.

Essential tags include:

og:title: The headline of your content.
og:description: A brief summary (2-4 sentences).
og:image: Large preview image (Recommended: 1200x630px).
og:url: Canonical URL of the page.

2. Twitter Cards

Twitter has its own proprietary system but falls back to Open Graph if Twitter tags are missing. Using explicit Twitter Card tags allows for more customization, such as the "Summary Card with Large Image" format.

Frequently Asked Questions

My image isn't showing up on Facebook?

Facebook aggressively caches link previews. If you've updated your tags but see the old version, use the Facebook Sharing Debugger to scrape your URL again.

What is the best image size for social cards?

The gold standard is 1200 x 630 pixels. This aspect ratio (1.91:1) works perfectly for Facebook, LinkedIn, and Twitter large cards. Keep important visual elements centered to avoid cropping on smaller mobile screens.

Why is my text being cut off?

Platforms have character limits for titles and descriptions. Keep your title under 60 characters and description under 200 characters to ensure the full message is visible without truncation.

Does this affect SEO rankings?

Indirectly, yes. While Google doesn't use OG tags for ranking, social cards drive more traffic and engagement from social media. Higher traffic signals can positively influence your overall search performance.

Can I use different images for Twitter and Facebook?

Yes! You can specify separate meta tags for each platform. Use og:image for Facebook/LinkedIn and twitter:image for Twitter. This allows you to optimize each image for the specific platform's recommended dimensions and style.

How do I test my social cards before publishing?

Use our preview tool above! For final validation, use platform-specific debuggers: Facebook Debugger, Twitter Card Validator, and LinkedIn Post Inspector.

Why should I use absolute URLs for images?

Social platforms crawl your page from their servers, not from your browser. Relative paths like /images/photo.jpg won't work because the crawler doesn't know your domain. Always use full URLs like https://example.com/images/photo.jpg.

What happens if I don't add social meta tags?

Platforms will attempt to generate a preview automatically by scraping your page content. This often results in ugly previews with wrong images (like a logo or random photo), truncated titles, or missing descriptions. Taking control with proper meta tags ensures your content looks professional when shared.

Best Practices for Social Media Cards

Image Optimization Tips

Use high-contrast images: Thumbnails are small, so bold colors and clear subjects work best.
Add text overlays carefully: Keep any text large and minimal - it should be readable at thumbnail size.
Test on mobile: Most social media consumption happens on phones where cards appear smaller.
Avoid excessive borders: Some platforms add their own borders, which can clash with yours.

Writing Effective Titles & Descriptions

Front-load keywords: Put the most important words first since truncation happens at the end.
Use action words: "Learn", "Discover", "Get" encourage clicks more than passive language.
Include numbers when relevant: "7 Tips" or "2024 Guide" perform better than vague titles.
Match user intent: Your description should promise what the user will actually get.

Platform-Specific Considerations

Each platform has subtle differences:

Facebook: Prefers 1.91:1 aspect ratio images, supports up to 300 character descriptions.
Twitter: Offers "Summary" (square) and "Summary Large Image" (wide) card types.
LinkedIn: Uses Open Graph tags, best results with images at least 1200px wide.
Discord/Slack: Both read OG tags excellently; they show the most information from your meta tags.
