Your <head> section is your page’s elevator pitch to Google and social networks — and most sites have broken or missing tags they never notice. Paste your head HTML below for a full audit: title and description length, Open Graph, Twitter cards, canonical, robots, charset, and duplicates — scored out of 100. No URL fetching (browsers block it), no uploads, no sign-up.

🎉 Free forever. No sign-up. No credit card. No limits.

This tool runs entirely in your browser — audit as many pages as you like, as often as you like.

How it works

Paste your <head> HTML and the tool parses it with the browser’s native DOM parser — the same engine that reads real web pages — then runs 15+ checks in milliseconds: title and description length against your slider settings, duplicate detection, all five core Open Graph tags, all four Twitter card tags, canonical validity, robots directives, viewport, charset, theme-color, and hreflang. Each check earns a pass, warning, or fail with the exact fix, and penalties roll up into an overall score out of 100 with a letter grade. Because everything happens locally, your page source never leaves your device — and no live URL fetching is attempted, since browsers block cross-site page reads.

Everyday uses

  • Bloggers — paste your theme’s head output after updates to catch missing descriptions or broken OG tags before publishing.
  • SEO freelancers — run client pages through the audit and drop the scored verdict list straight into site-audit reports.
  • Developers — verify templates render exactly one title, one description, and one canonical with valid absolute URLs.
  • Social media managers — confirm og:image and twitter:card tags exist so every shared link shows a rich preview, not a bare URL.
  • Site owners — spot accidental noindex tags that silently remove pages from Google.

Rule of thumb: keep titles under ~60 characters, descriptions between 120–160, and never ship a page without og:image — it’s the single tag that decides whether your link gets clicked on social.
