Audit Scores (Performance, SEO, Accessibility)
Measures how your site actually performs for a real visitor, page speed, technical SEO signals, and accessibility, by loading the live page in a real browser rather than guessing from a static scan.
Browser loads normally
Real score measured
Browser blocked (403)
Shown honestly as N/A
The exact same ring shown in your dashboard, not a redesigned mockup: a real measured score on the left, and the honest N/A state on the right when our browser can’t load the page at all.
How it works
These three scores, along with Best Practices, come from Lighthouse, Google's own open-source auditing engine, the same one behind the Lighthouse tab in Chrome DevTools and PageSpeed Insights. We run it ourselves: a headless Chromium browser on our own servers actually opens your page and runs dozens of checks, load timing, render-blocking resources, missing alt text, meta tags, and more.
We are not calling Google's PageSpeed API or any third-party scoring service. This is self-hosted and runs fresh on every audit, so the numbers reflect your site at that exact moment, not a cached or generic estimate.
This also means the result depends on our browser being able to load your page at all. If a site's firewall, WAF, or CDN blocks automated browsers, the same protection that can also block real search engine crawlers, Lighthouse cannot load the page and the affected scores show as not measured. We show that honestly as N/A instead of a misleading 0 or 100.
What this means for you
A high score means real visitors get a fast, accessible, well-structured page. A low score points to specific, fixable technical problems. N/A means our browser could not load your site to check, usually because of a server-side blocking rule, not that your site scored badly.
Known limitation
The Overall score is the average of Performance, SEO, and Accessibility, the three categories Lighthouse actually measures. HTTPS is checked separately and shown as a pass/fail indicator rather than folded into this average as a fourth score, since "does this site use HTTPS" is a yes/no fact, not something that benefits from being averaged in on a 0-100 scale. If Overall, Performance, SEO, or Accessibility show N/A, it almost always means the site is blocking automated browsers (the same 403/WAF issue that also blocks real search crawlers, which is itself flagged as a critical issue). Fixing that blocking rule is what allows these scores to be measured on the next audit.
