Why Website Speed Costs You Customers (And How to Fix It)

53% of mobile visitors abandon a website that takes longer than 3 seconds to load. Every additional second of load time reduces conversions by 7%. For a business generating EUR 10,000 per month online, a 2-second improvement could mean EUR 1,400 more per month - EUR 16,800 per year. Google has confirmed that page speed is a ranking factor, and with over 50% of UK traffic now coming from mobile devices, a slow mobile experience directly impacts both revenue and search visibility. Amazon found that every 100ms of added load time cost them 1% in sales.

Google evaluates your website on three Core Web Vitals. LCP (Largest Contentful Paint) measures how fast the main content loads - target under 2.5 seconds. INP (Interaction to Next Paint) measures responsiveness when users click or tap - target under 200 milliseconds. CLS (Cumulative Layout Shift) measures visual stability - target under 0.1 (no elements jumping around as the page loads). Sites that pass all three thresholds rank higher in search results.

Revylio websites are built on Next.js with automatic code splitting, image optimisation (AVIF and WebP formats), and server-side rendering. We use a global CDN for static assets, lazy-load below-the-fold content, and minimise JavaScript bundle sizes. Fonts are preloaded and self-hosted to eliminate external requests. The result: typical Revylio sites score 90+ on Google PageSpeed Insights for both mobile and desktop. We also implement structured data (JSON-LD) which helps search engines understand your content without additional rendering overhead.

With 50%+ of UK traffic from mobile devices and 63% of B2C orders in Germany placed on smartphones, mobile speed is where the gap between good and poor websites is most visible. Mobile users are on variable connections - 4G, sometimes 3G in rural areas. A site that loads in 1.5 seconds on desktop Wi-Fi might take 5+ seconds on mobile. Revylio designs mobile-first: the mobile version is optimised first, then enhanced for desktop. Every image, every animation, every script is evaluated for its mobile performance impact.
