Amazon converts at 10-15% (5-7x the 2.5-3% industry average). The plugin encodes every proven pattern that drives conversion: guest checkout, one-page checkout flows, product video (+86%), customer reviews (+270%), AI personalization (+15-25%), site search optimization (2-3x conversion multiplier), free shipping thresholds, mobile payment integration, and trust signal placement.
Jakob Nielsen calls 2026 "the year of AI agents" — the 3rd user-interface paradigm shifting from Conversational UI to Delegative UI. The plugin covers Amazon Rufus (250M+ users, 60% more likely to purchase), Shopify Agentic Storefronts, the Universal Commerce Protocol, trust calibration patterns, and structured data requirements (sites without schema markup lose 60% of AI visibility).
WCAG 2.2 Level AA compliance is non-negotiable. With the April 2026 ADA Title II deadline, 70% of accessibility lawsuits targeting e-commerce, and penalties of $75-150K per violation, the plugin provides complete checklists, ARIA patterns, testing procedures, and remediation guidance. Bonus: accessibility fixes boost conversions ~15%.
Framework-specific guidance for Next.js, Remix, and Astro. Core Web Vitals optimization (LCP <2.5s, INP <200ms, CLS <0.1). Headless commerce architecture (92% of US brands adopted). Modern CSS patterns (container queries, :has(), nesting). Image optimization (AVIF/WebP). Performance budgets and monitoring.
Cialdini's 7 principles applied ethically to e-commerce. Color psychology (orange CTAs outperform by 2.4-3.1%). Cognitive load reduction techniques. Social proof patterns backed by conversion data. Decision architecture for product pages. Ethical implementation guidelines — never dark patterns.
Current trends: bento grid layouts, nature-distilled palettes, dark glassmorphism, neo-brutalism matured, variable fonts (22% faster loads), kinetic typography, hand-drawn elements countering AI aesthetic. Dark mode support (82.7% adoption). Always accessible, always performance-conscious.
AR visualization (+94% conversion), WebGPU-powered 3D product viewers, shoppable video (3x conversion), voice commerce maturation, generative UI, Progressive Web Apps (33-76% conversion increases), social commerce ($1.2T market), and Zero-UI concepts.
