Frequently Asked Questions

What is an Open Graph tag?

Open Graph tags are HTML metadata that help social networks understand how a webpage should appear when it is shared.

Which Open Graph tags should a page have?

Important Open Graph tags commonly include og:title, og:description, og:url, og:type, og:site_name and og:image.

Why can Check URL fail?

Some websites block browser-based cross-origin requests using CORS. In that situation, the browser cannot read the remote HTML response. Paste the webpage source into the HTML fallback box instead.

Does this tool upload my HTML?

No. HTML pasted into the fallback checker is processed locally in your browser.

Is this Open Graph Checker free?

Yes. The tool is completely free to use.
