What is the best free SEO audit tool?
Seoxpert offers a free first scan with no credit card required — a full audit covering SEO, security, performance, accessibility, and GDPR/compliance. Google Search Console is also free but shows what Google has already done, not what will go wrong. Seoxpert is a website regression monitor for founders, agencies, and developers that runs all checks in a single pass and tells you what regressed since last time.
Truly free SEO audit tools fall into three camps: (a) free tiers of paid tools (Seoxpert, Ahrefs Webmaster Tools), (b) Google's own tools (Search Console, PageSpeed Insights), and (c) single-page inspection tools that do not crawl (securityheaders.com, validator.w3.org).
Google Search Console is essential — it shows you what Google actually did with your site, which queries drove impressions, and which URLs had indexing issues. It does not predict problems before they affect rankings.
Seoxpert's free first scan is a full audit: 20 detection categories run against the URL you submit, you get a 0–100 health score, a letter grade, and the full findings list. You can view the report on the web, and (after signup) export it as PDF or CSV. No credit card required.
For ad-hoc checks without a full scan, the free standalone tools are the meta description length checker, the robots.txt tester, and the redirect chain checker.
