Which OG tags are most important?

The four essential OG tags are: og:title (the headline), og:description (the summary, 1-2 sentences), og:image (1200x630px recommended), and og:url (the canonical URL). og:type and og:site_name are also important for optimal display.

What image size is best for Open Graph?

1200×630 pixels is the recommended size. This works perfectly for Facebook, LinkedIn, and Twitter. The image should be under 8MB, in JPG or PNG format. Avoid text-heavy images as they may be rejected by Facebook's ad policies.

Do I need both Open Graph and Twitter Card tags?

Yes, for best results. While Twitter falls back to OG tags when Twitter Card tags are missing, having both ensures optimal display on every platform. Use this tool alongside the Twitter Card Preview to verify both.

Why isn't my OG image showing on Facebook?

Common reasons: (1) image is too small (<200x200px), (2) wrong aspect ratio, (3) image blocked by robots.txt, (4) Facebook cache needs clearing via their Sharing Debugger, (5) image URL is relative instead of absolute.

What Is the Open Graph Preview?

Open Graph Preview is a free, browser-based SEO tool that fetches Open Graph meta tags from any URL and renders a live social card preview.

📋 When to Use the Open Graph Preview

Use before publishing blog posts, landing pages, product pages, or any content meant to be shared on social media. Essential for content marketers, SEO specialists, and developers who want to ensure their links look professional and engaging when shared on Facebook, LinkedIn, Discord, and Slack.

⚙️ How the Open Graph Preview Works

Enter any URL and the tool fetches the page's HTML via ToolStand's proxy server. It extracts all og:* meta tags using regex matching and renders a pixel-perfect Facebook-style link preview. Each platform tab shows a slightly different card layout matching how that platform displays shared links — Facebook shows a large card, LinkedIn similar but with minor differences, Discord shows a compact embed, and Slack shows a simple preview.

Frequently Asked Questions

What are Open Graph tags?

HTML meta tags that control how your page appears when shared on social platforms. They define title, description, image, URL, and type. Without them, platforms auto-generate previews that often look poor.

What's the recommended og:image size?

1200×630 pixels (1.91:1 ratio), under 8MB. This works for Facebook, LinkedIn, Twitter, and most social platforms. Use JPG or PNG format with minimal text overlay.

Why does my Facebook preview show old content?

Facebook caches OG data aggressively. Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) to force a re-scrape after updating your OG tags.

Can LinkedIn use the same OG tags as Facebook?

Yes. LinkedIn uses the same Open Graph protocol. The same og:title, og:description, og:image tags work for both platforms. LinkedIn also respects og:video for video content.

What if my og:image isn't loading?

Check that the image URL is absolute (starts with https://), the image file is accessible (not blocked by robots.txt or auth), the dimensions meet minimum requirements (200x200px), and the file size is under 8MB.

Is this tool free?

Yes, completely free — no sign-up and no API keys. A fair-use rate limit of 30 checks per minute per IP applies to protect the service.
