How to Generate Open Graph Tags for Social Media

Why Open Graph Tags Matter

When someone shares your page on social media, the platform reads your Open Graph tags to build the link preview card. Without them, the platform guesses which title, description, and image to use, often resulting in broken previews, missing images, or irrelevant content snippets.

• Control your brand appearance: OG tags let you decide exactly how your content looks when shared, ensuring consistent branding across every platform.
• Increase click-through rates: A well-crafted preview with a compelling title, description, and image drives significantly more clicks than a bare URL.
• Professional credibility: Pages with proper Open Graph tags look polished and trustworthy, while pages without them appear unfinished or neglected.
• Cross-platform compatibility: Open Graph tags are the standard recognized by Facebook, LinkedIn, Slack, Discord, Twitter (as fallback), and many other platforms.
• No dependency on page content: Even if your page title or meta description changes, OG tags ensure social previews remain consistent and controlled.

Essential Open Graph Properties

The Open Graph protocol defines several properties that control different aspects of the link preview:

• og:title The title of your page as it appears in the social preview. Keep it under 60 characters for best display.
• og:type The type of content (website, article, product, video, etc.). This determines which additional properties are available.
• og:description A summary of your page content. Keep it under 200 characters. This is the most important property for driving clicks.
• og:url The canonical URL of the page. This is used for deduplication on social platforms.
• og:image The URL of the image to display. Use 1200x630 pixels for the best cross-platform results.
• og:image:alt Alternative text for the image. Important for accessibility and required for compliance on some platforms.
• og:site_name The name of your website. Appears as a subtitle below the preview card.
• og:locale The language and region code (e.g., en_US). Defaults to en_US if not specified.

<meta property="og:type" content="article">
<meta property="og:description" content="Discover the top 10 SEO strategies that are driving results in 2026. From Core Web Vitals to AI-powered content optimization.">
<meta property="og:url" content="https://example.com/blog/seo-tips-2026">
<meta property="og:image" content="https://example.com/images/seo-tips-2026.jpg">
<meta property="og:image:alt" content="SEO Tips for 2026">
<meta property="og:site_name" content="My Blog">
<meta property="og:locale" content="en_US">

Example 2: Product Page

<meta property="og:title" content="Wireless Pro Headphones - Premium Sound">
<meta property="og:type" content="product">
<meta property="og:description" content="Experience studio-quality sound with 40-hour battery life. Free shipping on orders over $50.">
<meta property="og:url" content="https://shop.example.com/products/wireless-pro">
<meta property="og:image" content="https://shop.example.com/images/wireless-pro-hero.jpg">
<meta property="og:image:alt" content="Wireless Pro Headphones in black">

<meta property="og:title" content="GoToolly - Free Online Developer Tools">
<meta property="og:type" content="website">
<meta property="og:description" content="Free, privacy-focused developer tools that run entirely in your browser. JSON formatter, image compressor, QR generator, and more.">
<meta property="og:url" content="https://gotoolly.com/">
<meta property="og:image" content="https://gotoolly.com/assets/images/logo-512.png">

Common Open Graph Mistakes

• Missing og:image: Posts without images get dramatically less engagement. Always include an image with the correct dimensions.
• Image too small: Images smaller than 600x315 may not display on some platforms. Use 1200x630 for universal compatibility.
• Duplicate og:url: Using different og:url values for the same content causes platforms to create separate share entries, diluting engagement.
• Description too long: Descriptions longer than 200 characters get truncated. Write concise, compelling copy that fits within the limit.
• Forgetting og:image:alt: Missing alt text hurts accessibility and some platforms may not display the image without it.

Best Practices

• Create dedicated social images: Design images specifically for social sharing rather than reusing header images or thumbnails.
• A/B test your descriptions: Update OG descriptions periodically and measure which versions drive more clicks through social channels.
• Use absolute URLs: All og:url and og:image values must be absolute URLs with the https protocol.
• Validate before publishing: Use the Facebook Sharing Debugger and LinkedIn Post Inspector to preview how your tags will render.
• Keep og:title under 60 characters: Longer titles get truncated on most platforms, cutting off your message at the most critical point.
