One score for the messy reality of a website.
A 0-100 score computed across 11 audit categories, so launch teams can see the difference between a cosmetic nit and a blocker that needs fixing before traffic lands.
Scoring algorithm: PageLens v6
Built on real-world performance data.
The engineer behind PageLens AI spent over a decade at some of the world's biggest companies — digging through performance data, tracing checkout failures, and measuring the revenue impact of every millisecond of load time. Flying to client sites to figure out why a billion-dollar retailer's conversion dropped on a Tuesday afternoon.
That experience — knowing which technical issues actually move revenue and which are cosmetic noise — is what the scoring algorithm is built on. Not academic theory. Not a generic checklist. Real patterns from real production traffic at serious scale.
Now available to everyone.
That same methodology — distilled into an automated AI audit engine that crawls your site in a real browser, screenshots every page, and applies hundreds of checks across 11 dimensions. What used to require a senior performance consultant, a six-week engagement, and a five-figure invoice now takes five minutes and starts at $1.
- The AI does the detection. The score does the maths.
- Severity-weighted so blockers dominate, polish doesn't drown out real problems.
- Fairness-corrected so multi-page scans don't over-penalise the same underlying issue.
11 categories. One score.
Every finding is filed under exactly one category. The score balances all of them so no single dimension overwhelms the overall picture — a site with catastrophic performance but flawless SEO doesn't get a free pass, and vice versa.
Errors
Console exceptions, broken links, dead images, missing assets — the things that make a visitor distrust the page on first paint.
UX
Navigation clarity, form friction, tap-target sizing, signposting on long pages — the difference between a visitor finishing the task and bouncing.
Accessibility
WCAG-aligned checks for colour contrast, alt text, focus order, semantic landmarks and ARIA. Not just compliance — usability for the 1-in-5 visitors with assistive needs.
SEO
Title and meta hygiene, structured data, canonicals, OG tags, robots and sitemaps. What the search-engine and LLM crawlers see when they look at the page.
AI Search
Findings rolled up under this audit category.
Performance
Render-blocking weight, image sizing and format, layout shift, largest contentful paint. The numbers Core Web Vitals actually grades you on.
Design
Visual hierarchy, typographic rhythm, alignment, spacing, polish. The cumulative feel that signals premium vs template.
Content
Headline clarity, value-prop strength, scannability, jargon density, CTA copy. Whether the page actually says what it's for.
Security
TLS posture, cookie flags, mixed content, third-party script risk. Things a security reviewer would flag in a five-minute look.
Security Headers
Content-Security-Policy, HSTS, X-Frame-Options, Referrer-Policy and the rest of the security-headers checklist. Independently graded because it's a clean signal of operational maturity.
Tracking & Analytics
Tag manager presence, analytics pixels, consent management, Consent Mode v2 compliance, and ad conversion tracking. Whether the marketing stack is measurable, compliant, and not actively leaking privacy.
Not just another audit score.
Most audit tools give you a number and hope you trust it. Ours is designed to be defensible.
Deterministic
Same findings, same score. Every time. The AI detects the issues; the score is pure maths — no randomness, no mood, no second-guessing.
Versioned
Every scan is stamped with the scoring algorithm version it was computed under. When we evolve the weights, your historical badges and PDFs keep their original grade.
Fair across viewports
A site-wide issue observed on both desktop and mobile counts once, not twice. Multi-page scans don't inflate the score artificially — the number reflects reality.
Comparable
Site-to-site, deploy-to-deploy, month-to-month. The score is designed to trend — you can chart improvement across re-scans without rolling your own weighted average.
Grade bands
Numerical scores roll up to a single label so reports can speak human at a glance.
Mature production site. Most fixes are nice-to-have polish.
Solid foundation, a handful of medium findings worth a sprint.
Multiple high-severity findings. Quick Wins view will be busy.
A blocker or two on top of accumulated polish debt.
Critical issues — TLS, broken pages, security headers absent.
Versioned, not silently re-graded.
Every scan is stamped with the scoring algorithm version it was computed under (v6 today). When we evolve the weights, old scans keep their original score — your historical badges and report PDFs continue to mean exactly what they meant when they were issued.
Same number on the badge as on the report.
The verified-domain badge embeds the same score the report card shows — there's no "display rounding" or marketing-only number hiding the real one. The badge is also cryptographically signed so it can't be edited after the fact.
Common questions
Is the score reproducible?
Why don't you publish per-category sub-scores on the badge?
Does the score weight categories differently?
Can a perfect site really score 100?
What if I disagree with a finding?
How is this different from Lighthouse?
