Karpov Speed (30% weight)
v2.0: Core Web Vitals aligned speed measurement. Tracks Time to First Byte (TTFB), total load time (LCP proxy), render-blocking JavaScript and CSS, and total resource count.
Why it matters: Sites loading in 1 second convert 5x better than sites loading in 10 seconds. Amazon loses 1% of sales per 100ms delay. Speed is weighted 30% because research proves it's the primary driver of conversions and revenue.
Scoring factors: TTFB (<200ms good, >600ms poor) • Load time (<2.5s good, >4s poor) • Blocking scripts penalty • Resource count penalty
Tyche Interactivity (18% weight)
v2.0: Interaction to Next Paint (INP) proxy measuring page responsiveness. Heavily penalizes blocking JavaScript, third-party scripts (Google Analytics, ad networks), and rewards async/defer optimization.
Why it matters: Google elevated INP to Core Web Vital status in March 2024. Third-party scripts are the #1 killer of interactivity. Poor responsiveness drives user frustration and bounces.
Scoring factors: Third-party script count • Blocking JavaScript • Inline scripts • Async/defer bonuses • Resource preloading
Vortex Accessibility (8% weight - decreased from 12%)
v2.0: WCAG compliance fundamentals. Image alt text coverage, ARIA labels, semantic HTML (header, footer, nav, main), and screen reader compatibility.
Why it matters: Important for legal compliance and brand reputation. Weighted 8% because no published research links accessibility directly to conversion rates (unlike speed/SEO).
Scoring factors: Image alt text ratio • ARIA labels (5+ good) • Semantic HTML tags (8+ excellent) • Viewport for screen readers
Nexus Mobile (12% weight - increased from 10%)
v2.0: Comprehensive mobile experience scoring. Beyond viewport detection, now measures responsive images (srcset), mobile page size, touch-friendly elements, and semantic HTML structure.
Why it matters: 59% of web traffic is mobile, but mobile sites perform 87.8% worse than desktop. Google uses mobile-first indexing—your mobile performance determines all rankings.
Scoring factors: Viewport configuration quality • Responsive images (srcset) • Mobile page size (<1MB good) • Semantic HTML (touch targets)
Helix Privacy (6% weight - decreased from 10%)
v2.0: Security headers and tracker analysis. Counts third-party trackers (Google Analytics, Facebook Pixel, ad networks) and checks for HSTS, CSP, X-Frame-Options, X-Content-Type-Options.
Why it matters: Trust signal for users. Weighted 6% because excessive tracking primarily impacts Tyche (interactivity), not privacy per se.
Scoring factors: Tracker count (8 pts penalty each) • HSTS (10 pts) • CSP (15 pts) • X-Frame-Options (5 pts) • X-Content-Type (5 pts)
Pulse SEO (12% weight - increased from 8%)
v2.0: Search engine optimization fundamentals plus structured data. Checks title tags (30-60 chars optimal), meta descriptions (120-160 chars), Open Graph tags, canonical URLs, and Schema.org markup.
Why it matters: Core Web Vitals are now official Google ranking factors. Better rankings = more organic traffic = more revenue. Pulse increased to 12% weight because performance now directly affects SEO.
Scoring factors: Title presence/optimization • Meta description quality • Open Graph tags (4+) • Canonical links • Structured data (Schema.org)
Nova Scalability (7% weight)
v2.0: Infrastructure performance and global reach. Detects CDN usage (Cloudflare, Fastly, Akamai, CloudFront), cache-control headers with max-age, and compression (gzip/Brotli).
Why it matters: CDN and caching support speed (captured in Karpov). Critical during traffic spikes—Black Friday traffic can crash sites or slow them by 2x.
Scoring factors: CDN detection (30 pts) • Cache-control headers (15 pts) • Compression (gzip/Brotli, 15 pts)
Eden Efficiency (4% weight)
v2.0: Page weight and image optimization focus. Measures total page size, WebP/AVIF usage, lazy loading implementation, and image dimensions (prevents CLS).
Why it matters: Image optimization is the single highest-impact performance improvement for most sites. Weighted 4% because lean pages directly feed into Karpov (speed).
Scoring factors: Page size (<1MB good, >3MB poor) • WebP/AVIF usage • Lazy loading (loading="lazy") • Image dimensions specified
Aether Modern Tech (2% weight - decreased from 4%)
v2.0: Progressive Web App features and cutting-edge standards. Detects Service Workers, WebAssembly, ES6 modules, WebP images, and font-display optimization.
Why it matters: Enables advanced UX like offline functionality. Weighted 2% because no research shows direct conversion impact from cutting-edge tech.
Scoring factors: Service Workers (30 pts) • WebAssembly (25 pts) • ES6 modules (20 pts) • WebP images (15 pts) • font-display (10 pts)
Quantum Code Quality (1% weight - decreased from 3%)
v2.0: HTML standards compliance. Checks for DOCTYPE declaration and deprecated tags (center, font, strike, marquee, tt).
Why it matters: Valid HTML ensures cross-browser compatibility. Weighted 1% because code quality is hygiene with minimal direct business impact.
Scoring factors: DOCTYPE presence (30 pts) • Deprecated tag penalty (5 pts each, max -50)
Echo Green Hosting (Bonus Badge - not in P-Score)
v2.0: Environmental sustainability check via Green Web Foundation API. Verifies if hosting infrastructure uses renewable energy.
Why it matters: Brand reputation and environmental credentials. Shown as separate badge to avoid penalizing sites for infrastructure choices outside their control. No documented conversion impact.
Display: 🌱 Green Hosted badge if API confirms renewable energy • Otherwise no badge shown
