Why is this SEO audit free?
Most "free" SEO audit tools are lead-generation funnels that show you a score and hide the actual findings behind a paywall or email gate. SEOCheckPilot is built differently: every check, every finding, every AI recommendation is available to you immediately, no account required.
We believe web developers, solo founders, and marketers shouldn't need an enterprise subscription to understand why their site isn't ranking. Both the full audit and the targeted scan (pick 3 modules) are completely unlimited — run them as many times as you need.
Frequently asked questions
What does a free SEO audit check?
SEOCheckPilot's free SEO audit covers 22 modules: Core Web Vitals (real headless Chrome), on-page SEO, indexability, security headers, HTTPS, structured data, Open Graph, accessibility, mobile-friendliness, performance, redirect chains, and more.
How accurate is the Core Web Vitals data?
Core Web Vitals are measured using a real headless Chromium instance, not synthetic estimates. LCP, FCP, and TTFB are captured from actual page loads, giving you data that correlates closely with what Google experiences when crawling your page.
Can I audit competitor websites?
Yes — you can audit any publicly accessible URL, including competitor pages. Many users run a competitor's top landing pages through the tool to benchmark their own performance against the sites ranking above them.
Do I need to install anything?
No. The audit runs entirely server-side. Just enter a URL and click Audit Now — no browser extension, plugin, or desktop app required.
Is there a sitewide crawler?
Yes — the Site Crawler at /crawl will crawl up to 30 pages of your domain and run all modules on each page, giving you a full sitewide picture rather than a single-page audit.
