Performance & Core Web Vitals
Fast loading times are a must – for better rankings and happy visitors.
Learn more →NitroPack is an all-in-one performance solution that bundles caching, image optimization, critical CSS and CDN in the cloud and optimizes as aggressively as almost no other tool. The high PageSpeed scores are impressive, but the aggressive optimizations often cause layout issues and cache conflicts. We set up NitroPack so the scores are strong and the site still looks correct.
NitroPack works in the cloud and serves pages via its own CDN, which brings advantages but is also tricky. The aggressive optimization levels (standard, medium, ludicrous) shift scripts, generate critical CSS automatically and delay JS, which can break sliders, cookie banners, forms or cart interactions. Since NitroPack brings its own cache layer, conflicts arise when another caching plugin runs in parallel or the hosting itself already caches. Stale content after changes and problems with dynamic, personalized pages are also typical.
We first disable competing caching plugins and align NitroPack cleanly with your hosting cache. Then we choose the right optimization level instead of blindly setting "ludicrous", and define exceptions for critical scripts and dynamic pages. We check the automatic critical CSS and lazy load for CLS, exclude WooCommerce areas from cache, and set cache warmup and purge rules against stale content. All at €79/h incl. VAT, remote and without subscription.
