Social Preview Debugger

See how your page will look when shared on Facebook, Twitter, and LinkedIn. We read your Open Graph and Twitter Card tags, check image dimensions, and flag missing or conflicting fields.

Also try our Open Graph Checker, Schema Markup Validator, Meta Title & Description Checker.

What Is a Social Preview Debugger?

The Social Preview Debugger fetches your page and reads og:* and twitter:* tags to render share cards that resemble Facebook, Twitter, and LinkedIn. It checks image dimensions, highlights missing or conflicting tags, and suggests improvements to maximize clicks when your link is shared.

What This Tool Checks

Open Graph: og:title, og:description, og:image, og:url, og:type
Twitter Card: twitter:card, twitter:title, twitter:description, twitter:image
Image size: warns if the image is likely to crop or appear blurry
Conflicts: mismatched title/description between OG & Twitter

Tips for Better Link Previews

Use a large, uncluttered image (recommended: 1200×630).
Keep titles punchy (ideal 40–60 chars) and descriptions clear (ideal 90–110 chars).
Make sure the image URL is absolute, public, and not blocked by robots or cookies.
For Twitter, prefer summary_large_image for bigger previews.

Pro tip: Avoid dynamic or expiring image URLs. Many scrapers don’t execute JS or send auth cookies.
