Preview exactly how your page looks when shared on Facebook, X (Twitter) and LinkedIn. Check all Open Graph and Twitter Card tags, validate your og:image dimensions, and get pass/fail status on every required field.
Fetches the page server-side — just like Facebook, LinkedIn and X crawlers do.
Paste the full URL of any live webpage you want to check. The tool fetches the page source server-side (just like Facebook and LinkedIn crawlers do) and extracts every og: and twitter: meta tag found in the head section.
See live preview cards for Facebook, X (Twitter) and LinkedIn — rendered using your actual og:title, og:description, og:image and og:url values. Missing or incorrect tags are flagged immediately with specific guidance on what to fix.
Use the per-tag audit table to see exactly which tags are present, missing or malformed. Check that og:image uses an absolute HTTPS URL, that og:url matches the checked URL, and that image dimensions are close to the recommended 1200×630 pixels for optimal display across all platforms.
Open Graph tags are HTML meta elements in your page head that control how your page appears when shared on social media. og:title sets the headline, og:description the summary text, og:image the thumbnail, and og:url the canonical URL. Without them, social platforms guess from your page content — often poorly.
Facebook and LinkedIn primarily use og: tags. X (Twitter) uses twitter: tags first, then falls back to og: tags. LinkedIn may crop or resize images differently than Facebook. Discord and Slack also use OG tags but render them at different sizes. This checker shows previews calibrated for each platform.
The recommended size is 1200 × 630 pixels (1.91:1 aspect ratio). This renders well across Facebook, LinkedIn, Slack and Discord. X (Twitter) large card images should be at least 300 × 157 pixels. Images must use absolute HTTPS URLs — relative paths or HTTP URLs may not load in social crawlers.
Facebook caches OG data aggressively. After fixing og:image, use the Facebook Sharing Debugger (developers.facebook.com/tools/debug) to force a re-scrape. Common issues also include: image blocked by robots.txt, image too small (under 200×200px), image URL is relative not absolute, or the server blocks Facebook crawlers.
og:url should be the canonical URL of the page — the preferred version without UTM parameters, session IDs or other tracking strings. When og:url does not match the URL being shared, social platforms may show inconsistent share counts. This checker flags og:url mismatches as warnings.
Open Graph tags are not a direct ranking factor. However, they significantly influence click-through rate when pages are shared on social media. Higher CTR from social traffic sends positive engagement signals to search engines. Well-crafted OG tags that match your target keyword intent can indirectly support rankings.
