What Is a OG / Social Card Debugger?

An OG / Social Card Debugger helps you preview and troubleshoot how your web pages appear when shared on social media platforms. Open Graph (OG) meta tags control the title, description, and image that display in link previews on Facebook, Twitter/X, LinkedIn, Slack, and messaging apps.

This tool lets you enter your OG tag values and instantly see a simulated preview for each platform. It also generates the correct HTML meta tags you need to paste into your page's <head> section — eliminating the guesswork of social card formatting.

How to Use This Tool

  1. Enter your page details — Fill in the OG title, description, URL, and image URL. These are the core fields that social platforms read when generating link previews.
  2. Preview across platforms — See how your link will appear on Facebook, Twitter/X, LinkedIn, and Slack. Each platform renders cards slightly differently, so check all of them.
  3. Copy the generated meta tags — The tool generates the correct og: and twitter: meta tags. Copy them into your page's <head> section.
  4. Test after deployment — After adding the tags to your live page, use Facebook's Sharing Debugger and Twitter's Card Validator to clear cached previews and confirm the new tags are working.

Tips and Best Practices

Frequently Asked Questions

What is an OG (Open Graph) tag?+
Open Graph tags are HTML meta tags that control how your page appears when shared on social media platforms like Facebook, Twitter/X, LinkedIn, and Slack. They define the title, description, and preview image.
Why does my link preview look wrong?+
Social platforms cache OG data aggressively. If you updated your tags but the old preview still shows, use each platform's cache invalidation tool (Facebook Sharing Debugger, Twitter Card Validator) to force a refresh.
What image size should I use for OG?+
The recommended OG image size is 1200×630 pixels. This works well across Facebook, Twitter/X, LinkedIn, and most messaging apps. Use a 2:1 aspect ratio.
Does this tool fetch live data from my URL?+
This tool lets you input your OG tag values manually and preview how they will render across platforms. It does not fetch live page data — use it to test and refine your tags before deploying them.
What is a Twitter Card?+
Twitter Cards are Twitter/X's version of OG tags. They use meta tags like twitter:card, twitter:title, and twitter:image to control how links appear in tweets. This tool generates both OG and Twitter Card meta tags.
Do OG tags affect SEO?+
OG tags do not directly affect search engine rankings, but they significantly impact click-through rates from social shares. A compelling title, description, and image increase the likelihood that people click your shared links.
