Website Speed Optimisation Services for Growing Businesses

Website speed optimisation services have become essential as Core Web Vitals consolidate their role in Google's ranking algorithm. Sites failing LCP, CLS or INP thresholds see compounding ranking pressure, while sites that pass with margin pick up tie-breaker advantages in competitive SERPs. Beyond rankings, slow sites cost conversion rate — Amazon's classic data showed every 100ms of latency cost 1% in sales, and the impact only intensifies for mobile users on slower connections. Devintek runs website speed optimisation engagements for WordPress, WooCommerce, Shopify, Shopify Plus, Magento, Webflow, Wix Studio, React, Next.js and custom-built sites. Every engagement starts with a Core Web Vitals audit covering Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP), plus broader Lighthouse performance, accessibility, best practices and SEO scores. We use real-user monitoring data from Chrome User Experience Report (CrUX) where available, supplemented with synthetic testing across mobile and desktop. The audit identifies the specific bottlenecks: render-blocking resources, large unoptimised images, heavy JavaScript bundles, slow server response times, layout shifts from unset image dimensions, slow third-party scripts (chat widgets, analytics, ad tags), inefficient database queries, missing browser caching, missing CDN distribution. Remediation includes image optimisation (WebP/AVIF conversion, responsive serving, lazy loading), JavaScript optimisation (code splitting, deferring, removing unused code), CSS optimisation (critical CSS extraction, removing unused styles), server-side caching, CDN deployment (Cloudflare, BunnyCDN, AWS CloudFront), third-party script audit and reduction, font optimisation (preloading, subsetting), and platform-specific tuning (WordPress object caching, Shopify Liquid optimisation, Magento Varnish caching). Every optimisation engagement ends with verifiable performance metrics — before-and-after Lighthouse reports, Search Console Core Web Vitals confirmation after the 28-day field-data refresh window, and ongoing Real User Monitoring setup so performance is tracked permanently.
