Link Preview Checker

What Is a Link Preview Tool?

A link preview tool shows you exactly how your URL will appear when shared on social media platforms like Facebook, Twitter, LinkedIn, and messaging apps. That card you see with a title, description, and image? It's generated from your page's Open Graph tags and Twitter Card meta tags. If those tags are missing or misconfigured, your link looks broken, generic, or just plain ugly when shared.

Our tool fetches your page, reads the meta tags, and renders a preview of how it'll look on each platform. You see problems before your audience does — missing images, truncated titles, wrong descriptions. Fix them once and every share looks professional.

Why Link Previews Matter for Traffic

Social shares drive traffic. But a link with no image, a generic title, or a cut-off description gets ignored. People scroll past it. A well-configured preview with a compelling image and clear title gets clicks. It's the difference between your content being shared and being invisible.

This isn't just about vanity. Click-through rate from social media directly correlates with how good your link preview looks. A proper Open Graph image (1200×630px), a title under 60 characters, and a description under 155 characters — that's the formula for a preview that converts scrollers into visitors.

And it's not just social media. Messaging apps (WhatsApp, Slack, iMessage, Telegram) all generate link previews too. Every time someone pastes your URL in a chat, the preview is your first impression. Make it count.

Open Graph Tags Explained

Open Graph is a protocol created by Facebook that lets you control how your page appears when shared. The essential tags are:

• og:title — the title shown in the preview card. Keep it under 60 characters for best display across platforms.
• og:description — the description text below the title. Aim for 120-155 characters. Make it compelling — this is your pitch.
• og:image — the preview image. Use 1200×630px for optimal display. This is the single biggest factor in whether people click.
• og:url — the canonical URL for the page. Tells platforms which URL to display.
• og:type — the content type (website, article, product). Helps platforms categorize your content.
• og:site_name — your brand name. Shown alongside the URL on some platforms.

Twitter Card Tags

Twitter uses its own meta tags in addition to Open Graph:

• twitter:card — the card type. Use "summary_large_image" for a big image preview or "summary" for a smaller thumbnail.
• twitter:title — falls back to og:title if not set.
• twitter:description — falls back to og:description if not set.
• twitter:image — the image for Twitter cards. Same 1200×630px recommendation.

Pro tip: if you set Open Graph tags correctly, most platforms (including Twitter) will fall back to them. But setting Twitter-specific tags gives you more control over how your content appears on that platform specifically.

Common Link Preview Problems

No image showing. Either the og:image tag is missing, the image URL is broken, or the image is too small. Facebook requires at least 200×200px, but 1200×630px is the standard for large previews. Check that the image URL is absolute (starts with https://) and publicly accessible.

Wrong title or description. Platforms cache previews. If you've updated your tags but the old preview still shows, you need to clear the cache. Use Facebook's Sharing Debugger or Twitter's Card Validator to force a refresh.

Truncated text. Titles over 60 characters and descriptions over 155 characters get cut off on most platforms. Our tool shows you the character count so you can trim before publishing.

Generic preview. If no Open Graph tags are set, platforms try to guess — they'll pull the page title and first paragraph of text. The result is usually ugly and unhelpful. Always set explicit OG tags.

How to Use the Link Preview Tool

Enter any URL and the tool fetches the page, extracts all meta tags, and shows you:

• How the link looks on Facebook, Twitter, and LinkedIn
• All Open Graph tags found (or missing)
• All Twitter Card tags found (or missing)
• Article metadata (published date, author, modified date)
• Validation warnings for missing or suboptimal tags
• Specific recommendations for what to fix

Use it before publishing any new page, after updating meta tags, or when troubleshooting why a shared link doesn't look right. Also useful for checking competitor pages to see how they handle their social sharing setup.

Every page you publish gets shared somewhere — social media, Slack, email, messaging apps. How that link looks determines whether people click. Use our link preview tool above to check your Open Graph tags, Twitter cards, and social sharing appearance before your audience sees it. For the technical side of your URLs, check them with our redirect checker to make sure the URL itself resolves correctly before worrying about how it looks when shared.
