Natiad

Free SEO Audit Tool

Run a free website SEO audit online. This technical SEO audit tool checks indexability, meta tags, GEO readability, heading structure, links, and images, then groups findings by severity with plain-English fixes. Download your audit report. No signup required.

Audit any public page for technical SEO, on-page structure, and GEO readability from raw HTML.

Why use a free SEO audit tool?

A free website SEO audit tool scans your page for technical blockers that stop Google and AI crawlers from indexing and understanding your content. Fixing indexability, meta tags, heading structure, and broken links unblocks ranking potential, the foundation before content and authority work pays off.

Natiad's free SEO audit tool online reads raw HTML the way most crawlers do, including checks for Generative Engine Optimization (GEO). That makes it one of the best free SEO audit tools for agencies and site owners who need fast on-page and technical SEO audit results without a paid subscription.

How to run a free SEO site audit

  1. Enter your page URL

    Paste any public homepage, blog post, or landing page URL. This free SEO audit tool online works on live pages, no install or browser extension required.

  2. Run the SEO audit

    We fetch raw HTML (like Googlebot and AI crawlers do), then check indexability, meta tags, heading structure, GEO readability, links, and images.

  3. Fix issues by severity

    Review errors first, then warnings. Each finding includes why it matters and how to fix it. Download the audit report as a text file for your team or clients.
