E-Commerce: Load Time Optimisation
Every second of load time costs conversion — that's not a claim, it's measurable reality in any shop with analytics tracking. We run a structured performance audit, identify the biggest load time drivers at frontend and backend level, and implement measures with demonstrable impact: optimised assets, critical rendering path, database tuning. The result is a shop with green Core Web Vitals and measurable improvement.
Challenges you'll recognise
- Google Search Console shows poor Core Web Vitals for important pages but you don't know which measures would make the biggest difference.
- The shop loads significantly slower on mobile than desktop, and mobile bounce rates are correspondingly high.
- Load time problems have previously been addressed by server upgrades but the problem returns while costs increase.
Frontend Performance
Images not optimised for the web, unused JavaScript, render-blocking CSS — frontend issues are often responsible for the majority of perceived load time. We compress and convert images to modern formats, clean up JavaScript bundles, implement lazy loading, and optimise the critical rendering path for fast First Contentful Paint values.
Backend & Database
Slow database queries, missing indexes, and inefficient Shopware configuration are frequent causes of slow server response times. We profile database queries under realistic load, identify N+1 query problems and slow queries, and optimise precisely — without blanket measures.
Asset Optimisation
Product images at full resolution, CSS bundles without tree-shaking, and JavaScript loaded for every page although only needed on one subpage — these are classic, fixable performance drivers. We implement responsive images with srcset, WebP/AVIF conversion, CSS purging, and code splitting.
Core Web Vitals
Google evaluates LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift) as ranking factors. We measure these values with real user data (CrUX) and Lighthouse, identify the main causes of poor scores, and implement targeted measures for each metric.
Good to know
LCP is the most important single metric
Largest Contentful Paint measures when the most important visible content of a page finishes loading — typically the product image on product pages. This value has the strongest proven relationship with conversions and bounce rates and is the first optimisation entry point.
Server upgrades don't fix frontend problems
If the biggest load time driver is uncompressed images or render-blocking JavaScript, a faster server helps little. Frontend performance problems must be solved in the frontend — the right diagnostic step is a performance audit, not a hardware upgrade.
Real user data beats lab values
Lighthouse scores are measured in a controlled environment. CrUX data from Google Search Console shows what real users experience on real devices — including slow connections and older smartphones. Optimisations should always be measured against real user data.
