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 AI v11
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.
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 starts free, with Primary Scan from $1.
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.
Console exceptions, broken links, dead images, missing assets — the things that make a visitor distrust the page on first paint.
Navigation clarity, form friction, tap-target sizing, signposting on long pages — the difference between a visitor finishing the task and bouncing.
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.
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.
Findings rolled up under this audit category.
Render-blocking weight, image sizing and format, layout shift, largest contentful paint. The numbers Core Web Vitals actually grades you on.
Visual hierarchy, typographic rhythm, alignment, spacing, polish. The cumulative feel that signals premium vs template.
Headline clarity, value-prop strength, scannability, jargon density, CTA copy. Whether the page actually says what it's for.
TLS posture, cookie flags, mixed content, third-party script risk. Things a security reviewer would flag in a five-minute look.
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.
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.
Most audit tools give you a number and hope you trust it. Ours is designed to be defensible.
Same findings, same score. Every time. The AI detects the issues; the score is pure maths — no randomness, no mood, no second-guessing.
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.
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.
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.
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.
Every scan is stamped with the scoring algorithm version it was computed under (v11 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.
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.
