Free Open Graph Checker Tutorial – Complete Guide
Your Complete Guide to Social Media Preview Optimization
When you share a link on Facebook, Twitter, or LinkedIn, you want it to look compelling and professional. The Open Graph Checker analyzes your website's meta tags to ensure your links display beautifully across all major social platforms. This tutorial walks you through every feature so you can optimize your social presence with confidence.
Open Graph (OG) tags are special HTML meta elements that control how your website appears when shared on social media. Without proper OG tags, your shared links might show boring text instead of an attractive title, description, and image. The Open Graph Checker examines your tags and shows you exactly how your content will look on Facebook, Twitter/X, and LinkedIn.

Step-by-Step Usage Guide
Step 1: Get Your HTML Source
Due to browser security restrictions (CORS), the tool cannot directly fetch websites. Instead, you paste your page's HTML source code. Open your webpage in a browser, press Ctrl+U (or right-click and choose "View Page Source"), press Ctrl+A to select everything, then Ctrl+C to copy. You can also click "Try Demo" to see how the tool works with sample data.
Demo Mode Tip: Clicking "Try Demo" loads a fully optimized example showing proper Open Graph and Twitter Card tags. Use this to understand exactly what well-configured social tags look like in practice.

HTML Tools: Clean up your HTML with our
HTML formatter before analysis for better readability.
Step 2: Analyze Your Tags
Paste your copied HTML into the source code box and click "Analyze." Within seconds, you'll see every OG and Twitter tag listed with its status. Tags marked with a green checkmark are properly set, yellow warnings indicate issues like too-short or too-long content, and red errors show missing required tags. Each tag displays its actual content, character count, and best practice recommendations.
For tags with ideal length ranges (like og:title at 30-70 characters), a visual progress bar shows where your content falls within the optimal range. This helps you quickly see if your titles or descriptions might get truncated on social platforms.

Step 3: Review Social Previews
The social preview section shows exactly how your link will appear on each platform. Use the platform tabs (FB, Twitter, LinkedIn) to switch between previews. You'll see your title, description, and image in the same format users see when scrolling through their feeds. If any element is missing or improperly set, the preview clearly indicates "not set."
Image Requirements: For best results, your og:image should be at least 1200×630 pixels. The image checker section validates whether your image dimensions meet platform recommendations.

Step 4: Check Recommendations
The recommendations panel provides actionable suggestions sorted by priority. Critical issues (red) like missing og:title or og:image appear first, followed by warnings (yellow) for length issues, and informational items (blue) for optional improvements. Each recommendation explains exactly what to fix and why it matters.
Reading Your Results
Score Breakdown
The OG Score displays as a percentage with three category bars: Essential (OG title, description, image, URL, type), Twitter (card type, title, description, image), and Optional (site name, locale, image dimensions, image alt). Each bar shows how well you configured that specific category, making it easy to identify which areas need attention.
A score above 80% is excellent, meaning your social previews will look professional and compelling. Scores between 60-79% indicate good setup with room for improvement. Below 60% means critical tags are missing that significantly impact how your links appear when shared.

Frequently Asked Questions
What exactly are Open Graph tags?
Open Graph tags are HTML meta elements that tell social platforms how to display your content when shared. They include og:title (the headline), og:description (the summary text), og:image (the preview image), og:url (the canonical link), and og:type (content type like website or article). These tags appear in the section of your HTML.
Why can't I just enter a URL to check?
Browser security policies (CORS) prevent web pages from directly fetching other websites' content using JavaScript. By copying your page's source code (Ctrl+U → Ctrl+A → Ctrl+C) and pasting it into the analyzer, you bypass this limitation while receiving the same comprehensive analysis of your Open Graph configuration.
What's the difference between Open Graph and Twitter Cards?
Open Graph is primarily used by Facebook and LinkedIn, while Twitter Cards specifically control how your links appear on Twitter/X. While there's some overlap and Twitter can fall back to Open Graph values, explicitly setting Twitter Card tags ensures your content looks its best on each platform.
What image size do I need for social sharing?
The recommended minimum is 1200×630 pixels. This ensures your image looks sharp on high-resolution displays and across different screen sizes. Facebook specifically recommends this size and will crop smaller images or scale them in ways that might not look ideal.
Do Open Graph tags affect Google search rankings?
No, Open Graph tags don't directly influence Google search rankings. However, they critically impact how your content appears when shared on social media, which can drive significant traffic to your site. Compelling social previews increase click-through rates from social platforms.
What if my OG score is low?
A low score simply means critical tags are missing. Focus on the Essential category first add og:title, og:description, og:image, og:url, and og:type. These five tags have the biggest impact on how your content appears on social platforms. Work through the recommendations list systematically to improve your score.
