Why run a free SEO audit?

Most SEO problems are invisible until you look. Missing meta descriptions, broken canonical tags, slow response times, oversized images — none of these show up in a normal browser visit, but all of them quietly cost you Google rankings. A free SEO audit surfaces exactly what's wrong and what's working, in seconds.

Smart SEO Audit runs 50+ technical, on-page and content checks on any URL you paste above — the same checks a paid SEO consultant would run manually over several hours, delivered in under 10 seconds. No signup, no credit card, no catch.

What the free audit checks

Every audit covers the full technical foundation Google's crawler evaluates:

  • On-page SEO — title tag, meta description, H1, canonical URL, meta robots, language attribute
  • Technical setup — HTTPS, valid SSL certificate, HTTP/2, response time, server compression, page size, DOM size
  • Content quality — word count, text-to-HTML ratio, top keywords, heading structure
  • Media optimization — image formats, alt attributes, lazy loading
  • Links & structure — internal links, external links, unsafe links, Open Graph tags, social links
  • Indexability — robots.txt, meta robots, canonical URL, favicon, meta viewport

You get a clear score, a list of issues ranked by severity, and specific recommendations for what to fix first. For the full experience — including AI-written fix prioritization, scheduled rechecks, bulk audits, and branded PDF reports — check out our free and paid plans.
