How to Use the Link Preview Card Tester
Enter any URL and the tool fetches its Open Graph and Twitter Card meta tags to show exactly how the link will appear when shared on social media platforms like Facebook, Twitter, LinkedIn, and messaging apps.
The preview displays the title, description, image, and URL as they would appear in a social media post or chat message. Missing or incorrectly configured tags are flagged with specific recommendations for fixing them.
Test multiple URLs to ensure all your important pages — homepage, blog posts, product pages — have optimized link previews before sharing them on social media.
Why Use This Tool
When you share a link on social media, the platform pulls metadata from the page to create a preview card. If your Open Graph tags are missing, broken, or poorly configured, the preview may show a wrong image, truncated title, or no preview at all — significantly reducing click-through rates.
This tool lets you verify link previews before publishing, ensuring your content looks professional and compelling when shared across platforms.

Frequently Asked Questions
What are Open Graph tags?
Open Graph tags are HTML meta tags that control how your page appears when shared on social media. Key tags include og:title, og:description, og:image, and og:url. Facebook, LinkedIn, and most messaging apps use these tags to generate link preview cards.
What are Twitter Cards?
Twitter Cards are meta tags specific to Twitter (twitter:title, twitter:description, twitter:image, twitter:card) that control link previews in tweets. While Twitter also falls back to Open Graph tags, dedicated Twitter Card tags give you more control over the Twitter-specific appearance.
Why does my link show the wrong image?
This usually happens when the og:image tag is missing, points to a non-existent URL, or references an image that is too small. Social platforms typically require images to be at least 1200x630 pixels for optimal display. Use this tool to identify the specific issue.
How long does it take for social platforms to update previews?
Facebook caches link previews and may take time to update. Use Facebook's Sharing Debugger to force a cache refresh. Twitter updates relatively quickly. LinkedIn previews can be refreshed through their Post Inspector tool.
