Web Performance

Web performance describes the speed and responsiveness of a website from the user perspective. It is measured by Core Web Vitals like Largest Contentful Paint (load time), Interaction to Next Paint (responsiveness), and Cumulative Layout Shift (visual stability). Fast websites convert better, rank higher on Google, and reduce bounce rates.

Why does this matter?

Every additional second of load time measurably costs revenue: Amazon calculated that 100ms delay means 1% revenue loss. For mid-sized businesses, web performance is a direct competitive advantage: while competitors are still loading, your customer has already seen your offer — and Google rewards fast pages with better rankings.

How IJONIS uses this

We optimize web performance systematically: static generation with Next.js, image optimization with next/image and WebP/AVIF, code splitting for minimal bundle sizes, font subsetting, and CDN delivery via Vercel Edge Network. Our target: Lighthouse score of 95+ on desktop and mobile — measurable and verifiable.

Frequently Asked Questions

What are Core Web Vitals and why do they matter?

Core Web Vitals are Google's official metrics for user experience: LCP (load time under 2.5s), INP (responsiveness under 200ms), and CLS (layout stability under 0.1). Since 2021, they are a Google ranking factor. Poor scores cost you both search visibility and on-page conversions.

How fast should my business website load?

Under 2 seconds on mobile devices — ideally under one second. LCP under 2.5 seconds is Google's minimum for "good." Our Jamstack websites typically achieve LCP values of 0.5-1.2 seconds. Every 100ms improvement can increase conversion rates by up to 1%.
