Is There a Free SEO Audit Tool?

Free SEO audit tools do exist, and the two most useful are Google Search Console, which is entirely free with no limits, and Screaming Frog's free tier, which crawls up to 500 URLs before requiring a paid license. Together they cover most of what a small site needs for a basic audit.

The free tier limits become a real constraint for larger sites, since 500 URLs is a small fraction of many business websites. At that point, either a paid crawler license or software that automates the full audit process becomes worth the cost simply to see the complete picture.

Agencies past that free-tier ceiling often move straight to agency SEO software for unlimited, ongoing site monitoring.
