FAQ
Website Speed Optimization - FAQ
Core Web Vitals are Google's metrics for user experience: LCP (Largest Contentful Paint) measures loading speed, INP (Interaction to Next Paint) measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. All three affect your Google rankings.
Speed audits and basic optimization start from €400. Comprehensive optimization including server-side improvements, image optimization, code refactoring, and CDN setup typically ranges from €800–€2,000 depending on the site's complexity.
Results vary, but we typically achieve 40–70% improvement in load times. Most sites reach 'Good' Core Web Vitals scores after optimization. We provide before/after metrics so you can see the exact improvement.
Yes. Google has confirmed that page speed and Core Web Vitals are ranking factors. Faster sites also have lower bounce rates, higher engagement, and better conversion rates - a 1-second delay can reduce conversions by 7%.
Yes. We optimize WordPress, WooCommerce, Shopify, and custom-built sites. Common improvements include image optimization, lazy loading, caching, code minification, CDN implementation, and server-side rendering.
Website Speed Optimization for Better Performance
Website speed directly impacts your bottom line. Studies show that a one-second delay in page load time can reduce conversions by seven percent, and Google uses page speed as a ranking factor. Website speed optimization at Kosmoweb is a systematic process that identifies and eliminates performance bottlenecks, delivering faster load times that improve both user experience and search rankings.
Our speed optimization process includes image compression and next-gen format conversion, code minification and bundling, server response time improvements, browser caching configuration, lazy loading implementation, and critical rendering path optimization. We measure results using Google PageSpeed Insights, Core Web Vitals, and real-user monitoring data to ensure improvements translate into better experiences for your actual visitors.
Performance is not a one-time fix. As you add content, install plugins, or update your platform, site speed can degrade over time. Our website management services include regular performance audits and proactive optimization to keep your site fast. Whether your site is built on WordPress, Shopify, or a custom platform using React and Next.js, we know how to squeeze every millisecond of performance.
Fast websites rank higher, convert better, and provide a superior user experience. Businesses in Prague and across the Czech Republic trust us to optimize their sites for speed. Combined with SEO optimization and thoughtful web design, speed optimization completes the trifecta of a high-performing website that delivers real business results.
