Frequently Asked Questions
What does GuardianScan check?
50+ checks across 6 categories. Performance covers Core Web Vitals (LCP, TBT, CLS). Security checks HTTPS, headers, and CSP policies. Accessibility tests WCAG 2.2 Level AA compliance. SEO checks meta tags, schema markup, and semantic HTML. Modern Standards looks at framework patterns and optimisations. Code Quality covers bundle size and console errors.
How long does a scan take?
About 45 seconds for most sites. The 50 checks run in parallel for speed. Scan duration may vary based on your site's performance and size.
Is there a free tier?
Yes. Free accounts get one complimentary scan delivered as a PDF report to your email. Enter a URL to get a full 50-point report. For unlimited scans, full dashboard access, scan history, and detailed reports, upgrade to Professional.
How much does it cost?
£24/month for Professional (unlimited scans, full dashboard, scan history). Free tier gets one scan delivered as a PDF report via email. Launching 1st November 2025.
What makes this different from Lighthouse?
We run Lighthouse for performance and accessibility scoring, then add security header checks, SEO validation, and framework-specific audits. Lighthouse covers part of the picture. We check everything that matters for modern websites - security, SEO, framework optimisation - in one scan with stored history.
Can it scan private or staging sites?
Yes, as long as the URL is accessible over HTTP/HTTPS. We scan via web requests, so the site needs to be reachable from the internet. We can't analyse source code or private repositories.
What's checked for accessibility?
WCAG 2.2 Level AA compliance including keyboard navigation, screen reader support, colour contrast (4.5:1 minimum), touch targets (48px minimum), and semantic HTML. Automated checks catch about 70% of issues - manual testing still needed for full compliance.
Does it work for AI search optimisation?
Yes. We check schema.org markup and semantic HTML structure that AI search engines use to parse and understand your content.
