    Frequently asked questions

    Can I enter a URL instead of pasting HTML?

    No. Browsers cannot fetch other sites' HTML from client-side JavaScript. Paste page source from View Source (Ctrl+U / Cmd+Option+U), your CMS, or a saved file.

    What does it check?

    Title length, meta description, canonical, Open Graph basics, and Twitter Card — with pass/warning/error for each.

    Is my HTML uploaded?

    No. Everything runs locally in your browser.

    Need to create tags instead?

    Use the Meta Tag Generator to build tags from scratch.
