Why an HTML-based SEO audit?

Many SEO tools require crawling a live URL. SEO Audit Lite flips that model—you paste HTML directly, and the audit runs in your browser. That makes it ideal for prototypes, staging environments, internal tools, and generated HTML that never lives on a public URL.

Use it alongside your favorite crawler: fix template-level issues here first, then crawl fewer pages and catch fewer surprises.

What this SEO audit checks

  • Title and meta description presence and length
  • H1 usage, heading hierarchy, and empty or repeated headings
  • Canonical tag, Open Graph tags, and robots meta configuration
  • Viewport meta, charset, HTML lang, and JSON-LD structured data
  • Image alt coverage and lazy-loading usage for performance

Once you’ve fixed HTML issues here, use complementary tools to polish SERP appearance and content:

Privacy-first SEO auditing

SEO Audit Lite is built for sensitive work: client pages, unreleased features, or internal dashboards. The tool never sends your HTML anywhere—everything runs on the client using native browser APIs.

You can close the tab at any time and your content disappears with it. No accounts, no tracking scripts, no surprise requests.

Frequently Asked Questions

What does SEO Audit Lite do?

It analyzes pasted HTML for on-page and technical SEO signals: title, meta description, headings, canonical, Open Graph, robots meta, viewport, structured data, and image alt text. You get a weighted SEO score and clear, fix-focused guidance.

Do you store or send my HTML?

No. The audit runs 100% in your browser using DOMParser. Your HTML is never sent to a server, stored, or logged. It’s a privacy-first SEO helper for sensitive pages and internal tools.

What HTML should I paste?

Paste full page HTML (View Source) for best results, or at least the head and a portion of the body so title, meta tags, canonical, H1, headings, and images are present. Fragments are auto-wrapped for safe parsing.

Is this a replacement for full SEO crawlers?

Think of this as a fast, HTML-level analyzer, not a full crawler. It’s ideal for spot-checking templates, staging pages, generated HTML, and single-page fixes without connecting to a site or API.
