How to Check Your Open Graph Meta Tags Testing your social media link previews takes just one click. Follow these steps:

  1. Enter Your URL: Paste the exact webpage link (URL) you want to test into the search bar.

  2. Fetch the Data: Click "Check." Our tool instantly crawls your webpage's HTML to extract your active meta tags.

  3. View Link Previews: Scroll down to see high-fidelity mockups of exactly how your link will look when pasted into platforms like Facebook, Twitter, and LinkedIn.

  4. Identify Errors: We display a raw list of your discovered og:title, og:image, and og:description tags, highlighting any missing or broken elements so you can fix them in your code.

Why Are Open Graph (OG) Tags Important? Have you ever shared a link in a group chat only for it to show up as a blank gray square with no title? That happens when a website lacks Open Graph tags. Originally created by Facebook, OG tags are snippets of HTML code that control how URLs are displayed when shared across the internet.

  • Boost Click-Through Rates (CTR): A link with a massive, eye-catching image and a compelling title gets dramatically more clicks than a plain text URL.

  • Control Your Brand Identity: Instead of letting social media platforms randomly scrape the first image or paragraph they find on your page, OG tags let you dictate exactly what users see.

  • Universal Standard: Almost all major platforms — including LinkedIn, Pinterest, Slack, Discord, and iMessage — use Open Graph data to generate rich link previews.

How to Fix a Missing Link Preview Image The most common Open Graph issue is a broken or missing thumbnail image. If our checker shows that your image is missing, ensure you have checked the following:

  • Missing Tag: Ensure the <meta property="og:image" content="URL_HERE" /> tag actually exists in the <head> of your HTML.

  • Relative vs. Absolute URLs: Your image URL must be absolute (e.g., https://yourwebsite.com/image.jpg). It cannot be a relative path (e.g., /images/pic.jpg).

  • Image Dimensions: Social platforms have strict requirements. Your OG image should ideally be 1200 x 630 pixels for the highest quality display across all networks.

Fast, Secure, and Private Auditing FusionTools is designed for modern web developers. When you use our Open Graph Checker, we simply fetch the public meta data of your URL to display the results. We do not store your queried URLs, cache your images on our servers, or log your development activity, ensuring your upcoming marketing campaigns and staging links remain private.

Frequently Asked Questions

Common questions about this tool

What is the difference between Open Graph and Twitter Cards?

Open Graph (og:) is the universal standard created by Facebook and used by almost everyone (LinkedIn, Slack, Discord). Twitter created its own proprietary tags called 'Twitter Cards' (twitter:). However, if Twitter cannot find a Twitter Card tag on your site, it will automatically fall back and use your Open Graph tags instead.

Why is my image not showing on Facebook or LinkedIn?

If our tool shows your image, but Facebook does not, it means the platform has cached an older version of your webpage from before you added the image. To fix this, you must clear their cache using the official Facebook Sharing Debugger or the LinkedIn Post Inspector to force them to 'scrape' your page again.

What is the best size for an Open Graph image?

To ensure your image looks crisp on high-resolution displays (like Retina screens) and isn't awkwardly cropped, you should size your og:image to exactly 1200 pixels wide by 630 pixels tall.

Can I check URLs from a local staging environment?

No. Because our tool needs to fetch the data over the internet, the URL you enter must be publicly accessible. Localhost links (like http://127.0.0.1:3000) cannot be reached by external crawlers.

Which OG tags are absolutely required?

To generate a basic rich preview, you must have at least four tags in your HTML header: og:title (the name of the page), og:type (usually 'website' or 'article'), og:image (the URL of your thumbnail), and og:url (the canonical link to the page).
