    Frequently asked questions

    Can I enter a URL instead of pasting HTML?

    No. Browsers block websites from fetching other sites' HTML (CORS). Paste the page source from View Source (Ctrl+U), your CMS, or a saved file.

    What does the meta tag checker analyze?

    Title length, meta description, canonical URL, Open Graph tags, and Twitter Card tags — with pass, warning, and error levels.

    Is my HTML sent to a server?

    No. Parsing and analysis run entirely in your browser.

    How is this different from the meta tag generator?

    The generator creates tags from scratch. The checker audits existing HTML and flags SEO issues.
