SEO Audit
Paste a page's HTML and get an instant on-page SEO report with a 0–100 score. It runs locally in your browser; nothing is uploaded.
What it checks
- Title tag — present, non-empty, and within the recommended 10–60 characters.
- Meta description — present and within the recommended 50–160 characters.
- H1 heading — exactly one
<h1>on the page. - Heading hierarchy — no skipped levels (e.g. an
<h2>jumping straight to<h4>). - Image alt text — every
<img>has non-emptyalttext. - Canonical link — a
<link rel="canonical">is present. - Open Graph tags —
og:title,og:descriptionandog:imagefor rich social previews.
Each check is scored as a pass, warning, or failure, and the results roll up into an overall score and letter grade.
Good for
- A quick on-page SEO sanity check before publishing a page.
- Spotting missing meta tags, alt text, or social-preview tags.
- Reviewing a CMS export or a hand-written template.
FAQ
Is my HTML uploaded?
No — the audit is compiled to WebAssembly and runs entirely in your browser tab.
Does it crawl my site or fetch the live page?
No. It only analyses the HTML you paste — view-source and paste, or paste your template.
What score is good?
90+ (grade A) means all the basics are covered. Warnings are worth fixing but won't block indexing; failures usually should be addressed.
