What is Open Graph Checker

Open Graph Checker is a free online tool that helps you analyze and validate a webpage’s social sharing metadata. It automatically retrieves the HTML source from your provided URL and extracts key Open Graph and Twitter Card tags — such as the title, description, and image.

The tool also generates instant preview mockups for Facebook and Twitter, allowing you to see exactly how your content will appear when shared on social media platforms. This helps ensure your links look clean, engaging, and optimized for clicks.

What is Open Graph?

Open Graph is a metadata protocol originally developed by Facebook that allows web pages to become rich objects in a social graph. By adding specific meta tags (e.g., og:title, og:description, og:image, og:url) within your page’s <head> section, you can control how your content appears when shared across platforms like Facebook, LinkedIn, Twitter, and others.

These tags determine the title, summary, and thumbnail image that accompany your link. Properly configured Open Graph data improves the visual appeal of shared content, enhances engagement, and boosts click-through rates (CTR) on social posts.

Core Components

The protocol uses specific <meta> tags placed in your HTML <head> section:

<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="Compelling description of your content" />
<meta property="og:image" content="https://example.com/image.jpg" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:type" content="website" />

How Does the OG Image Checker Work?

The Open Graph Checker operates through a sophisticated multi-step process:

Step 1: Secure Page Retrieval

When you submit a URL, the tool:

Sends a secure HTTPS request to fetch your page
Retrieves the complete HTML document
Handles redirects and modern JavaScript-rendered content
Respects robots.txt and security protocols

Step 2: Intelligent Parsing

The checker then:

Scans the <head> section for all meta tags
Identifies both Open Graph (og:*) and Twitter Card (twitter:*) properties
Extracts Facebook-specific tags and extended metadata
Detects LinkedIn-optimized tags

Step 3: Validation & Analysis

According to ogimage.info, the tool validates:

Image dimensions and aspect ratios (recommended: 1200×630 pixels)
Title length (optimal: 60-90 characters)
Description length (optimal: 150-200 characters)
URL structure and accessibility
Required vs. optional tag presence

Step 4: Preview Generation

The checker creates accurate mockups showing:

Facebook feed preview with correct aspect ratios
Twitter card layouts (summary and large image variants)
LinkedIn sharing preview
WhatsApp, Slack, and Telegram representations

What is the purpose of Open Graph images?

Open Graph images are the thumbnail visuals shown next to your link when shared on social media. They act as visual cues that attract attention and communicate your content’s message before users even click.

A well-optimized OG image should:

Be high-quality, relevant, and visually engaging
Match the recommended size of 1200×630 pixels for best results
Represent your brand or article content clearly
Include safe margins and readable text if using overlays

Correctly formatted images can dramatically increase the shareability of your posts and create consistent branding across multiple social platforms.

How To Use the Open Graph Checker Tool?

Enter your full page URL (including https://) into the input field.
Click “Submit” to fetch and analyze the page’s metadata.
Review the Meta Data section to confirm your og:title, og:description, and og:image values.
Inspect the Meta Tags list to ensure all Open Graph and Twitter Card tags are properly set.
Check the live previews for Facebook and Twitter to verify how your link will appear when shared.

With this quick and easy process, you can optimize your webpage’s appearance across all major social media networks before hitting “publish.”
