On-Page SEO Inspector

Paste HTML (view-source) to check title, meta description, heading hierarchy, canonical, robots, image alt attributes, links and Open Graph tags. Live URL fetching is disabled in this static build so the tool cannot reach localhost, private IPs or cloud metadata.

How to use it

  1. Open the page you control, view source, and paste the HTML.
  2. Optional: type a public URL. This version will not fetch it; paste HTML instead when CORS would block the browser.
  3. Run the audit, then copy or download the issue report.

Sample HTML is intentionally incomplete: short title, noindex, skipped H2, missing alt and no canonical.

Blocked hosts include localhost, private ranges, .internal and metadata endpoints. Server-side fetch is not implemented.

Issue report

Paste HTML or a public URL to run the audit.

Privacy and security

HTML is parsed in your browser. Scripts inside pasted markup are not executed. There is no server fetch, so SSRF against internal networks is not possible from this page.

    FAQ

    Why can’t I fetch a live URL?

    A browser request would hit CORS. A server fetch would need SSRF controls we are not running in this static host. Paste HTML instead. That check is labelled N/A.

    Does a pass mean the page will rank?

    No. This is a field checklist on the HTML you pasted, not search ranking.

    Are JavaScript-rendered titles visible?

    No. Only the HTML string you paste is read. Client-rendered tags will be missing unless you paste the rendered DOM.
