Website SEO Audit

Scans a single page for common on-page SEO issues

Checks one page at a time (not a full-site crawl): title, meta description, headings, images, canonical, viewport, robots, Open Graph, favicon, content length, load time, HTTPS.

What Is an SEO Audit Tool?

An SEO audit tool checks a webpage against a list of common on-page SEO factors — things like title length, meta description, headings, and image alt text — and reports what's missing or worth fixing.

How to Run an SEO Audit

1

Enter a URL.

2

Press "Run Audit."

3

Review the score and each check below it.

Is This SEO Audit Tool Free?

Yes — there's no paywall, no watermark, and no sign-up required.

What This Audit Checks

  • HTTPS and HTTP status
  • Title tag and meta description length
  • H1 heading (present, and exactly one)
  • Image alt text
  • Canonical tag and mobile viewport tag
  • Robots meta (noindex check) and HTML lang attribute
  • Open Graph tags and favicon
  • Content length and page load time

How the Score Is Calculated

Each of the 13 checks has a weight based on how much it typically matters. A pass earns its full weight, a warning earns half, and a fail earns none — the score is the total earned as a percentage of what was possible.

Does It Crawl My Whole Site?

No — it checks one page per run, the exact URL you enter. Run it again on each page you care about (homepage, key landing pages, blog posts) rather than expecting one run to cover the whole site.

Does It Render JavaScript?

No — it reads the raw HTML that comes back from the server, the same way a basic crawler would. If your page builds its title, meta tags, or main content with client-side JavaScript after the page loads, this audit won't see that content and may report it as missing.

Fixing Common Issues It Finds

  • Missing meta description — add a 120-160 character summary of the page
  • Title too short or long — aim for 30-60 characters
  • No H1, or more than one — use exactly one per page
  • Images missing alt text — describe what each image shows
  • No viewport tag — add one for mobile-friendliness

How Often Should You Run an Audit?

Any time you change a page's title, meta tags, or content — it's a quick way to confirm nothing regressed, especially right before or after a deploy.

Is It Safe to Audit a URL Here?

Yes — the page is fetched and checked for that one request and isn't saved anywhere. No account or sign-up is required to use it.
