Frequently Asked Questions
How does My Website Auditor differ from GTmetrix?
GTmetrix focuses primarily on page speed performance using Lighthouse and Web Vitals. My Website Auditor (MWA) goes beyond speed — we run 200+ checks across Core Web Vitals, technical SEO, CSP security policies, cookie configurations, and WCAG accessibility in a single 60-second scan, providing exact code locations and reproducible cURL verification steps.
Does GTmetrix check security headers?
No. GTmetrix is a performance-focused tool and does not analyze security headers, Content Security Policy directives, cookie flags, or leaked credentials. MWA includes full security auditing in every scan.
Is My Website Auditor free?
Yes. You can run instant audits on any public website for free with zero credit card required. Registered accounts get a monthly free scan quota, with paid plans for unlimited audits.
Can I use MWA alongside GTmetrix?
Absolutely. Many teams use GTmetrix for ongoing performance monitoring and MWA for comprehensive diagnostics that cover the categories GTmetrix does not (security, SEO, accessibility).
