What is an Open Graph Checker?
An Open Graph Checker is a free tool that validates, previews, and optimizes your Open Graph meta tags so your content appears perfectly when shared across social media platforms like Facebook, X (formerly Twitter), and LinkedIn.
Discover how your website is perceived by search engines and social networks. Our tool scans your webpage's HTML code, detects missing or malformed og tags, and shows you exactly how your link previews will display to users—before you hit share.
Why Use an Open Graph Checker?
Social media platforms use the Open Graph protocol—originally developed by Facebook—to generate rich link previews. When someone shares your website, these platforms read your Open Graph tags to pull your title, description, image, and URL.
Missing or incorrect meta tags lead to broken images, truncated titles, and poor engagement. The result? Lower click-through rates and missed traffic opportunities.
Our free Open Graph Checker solves this by:
- Validating all critical og:title, og:description, og:image, og:url, and og:type tags
- Showing live previews for Facebook, X, and LinkedIn
- Diagnosing image issues like incorrect dimensions or unsupported file types
- Providing ready-to-use HTML code snippets to fix errors fast
Whether you're a developer optimizing markup or a content creator preparing a blog post, this tool ensures your web pages look professional and appeal to your audience every time they're shared.
Key Features
Live Social Media Preview
See exactly how your title tag, meta description, image, and URL appear on Facebook and X. Our preview generator shows real-time results across multiple platforms so you can ensure consistent branding.
Complete Meta Tag Validation
The checker validates all essential Open Graph meta tags including og:title, og:description, og:image, og:url, og:type, and og:locale. We also scan Twitter Card tags (twitter:card, twitter:title, twitter:image) and identify fallback metadata when Open Graph tags are missing.
Image Diagnostics
Images drive engagement on social networks. Our tool checks that your Open Graph images meet platform requirements:
- Minimum dimensions of 1200 x 630 pixels for high-resolution devices
- Proper aspect ratio and file type
- HTTP status and CDN accessibility
- Recommendations to use images that are at least 1200 x 630 pixels to enhance visual appeal
Crawl Simulation
We emulate how social media crawlers access your site, revealing issues with robots.txt, authentication, redirects, or server blocks that prevent platforms from reading your content.
