How the tool works

Three public data sources, aggregated in parallel, no data stored long-term.

1

PageSpeed Insights

Google's official API scans your site in both mobile AND desktop mode, returning the 4 Lighthouse scores (Performance, Accessibility, Best Practices, SEO) with Core Web Vitals (LCP, INP, CLS, TBT).

2

Mozilla Observatory v2

Mozilla's reference tool scans 10+ HTTP security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy…) and returns an A+ to F grade, required for GDPR and NIS2 compliance.

3

Gap analysis

Your scores are compared to the heliorank.lu baseline (100/100/100/100, Mozilla A+ 100). The gap is quantified metric by metric. You immediately see the first optimisation priority.

Frequently asked

What exactly does this tool measure?

Two dimensions: (1) Lighthouse performance via Google's official PageSpeed Insights API, in mobile AND desktop, across the 4 Lighthouse categories (Performance, Accessibility, Best Practices, SEO); (2) Mozilla Observatory v2 security (A+ to F grade based on 10+ HTTP headers: HSTS, CSP, X-Frame-Options, etc.).

Why compare my site to heliorank.lu?

Heliorank.lu serves as a concrete reference: 100/100/100/100 Lighthouse mobile and desktop + Mozilla A+ 100/100. These scores are publicly verifiable. The quantified comparison shows exactly how many points your site needs to gain to match the level of a professionally optimised site.

Are my URL or scores stored?

URL and scores are cached for 1 hour in Cloudflare KV to avoid repeated scans. No data is shared with a third party. If you request a detailed email report, your email is transmitted to HELIORANK only, in accordance with our GDPR policy (deletion on request).

Does this diagnostic replace a full audit?

No. The tool gives a surface view: 4 Lighthouse scores + Mozilla grade. A full HELIORANK audit (€2,500 ex-VAT, fixed fee) additionally covers: Schema.org architecture, multilingual hreflang, crawl budget, custom headers, prioritised action plan, 90-day roadmap. The diagnostic is a starting point, not a deliverable.
