// SERVICE · SPEED OPTIMIZATION

Quoted per project

Cut your website's load time.
Keep the design.

Website speed optimization for sites already in production. We audit your existing site, find what slows it down and fix it — without touching the design. The goal: faster pages and better Core Web Vitals on mobile and desktop.

Every second of delay costs you customers

It's well documented that slow pages lose visitors: many people leave before a page has finished loading, and fewer of those who stay go on to buy or get in touch. On mobile connections the effect is even more noticeable.

Our website speed optimization service tackles this step by step. We audit your existing site on mobile and desktop, identify the bottlenecks and implement targeted fixes — measuring before and after so you can see what changed.

How we measure the results

Before we change anything, we record baseline measurements of your key pages: Lighthouse scores, Core Web Vitals, page weight and render-blocking requests. When the work is done, we run the same measurements again and share a before/after report based on your own site's numbers.

What's included in the speed optimization audit

◆ 01 · AUDIT

Full performance scan

Lighthouse, WebPageTest, Chrome DevTools, GTMetrix, real-user data where available. We map the bottlenecks across mobile and desktop.

◆ 02 · IMAGES

WebP/AVIF + lazy load

Convert legacy JPG/PNG to modern formats. Responsive srcsets. Native lazy loading. CDN-served.

◆ 03 · JAVASCRIPT

Code splitting & defer

Bundle analysis, tree shaking, code splitting, deferred non-critical scripts, async loaders, third-party script audit.

◆ 04 · CSS

Critical CSS inline

Extract above-the-fold critical CSS inline. Defer non-critical stylesheets. Remove unused CSS.

◆ 05 · CACHING

Brotli + edge CDN

HTTP caching rules, Brotli compression, edge CDN delivery, stale-while-revalidate strategy.

◆ 06 · FONTS

Subset & preload

Subset web fonts, preload critical fonts, font-display: swap, variable fonts where possible.

Core Web Vitals · the SEO ranking signal

Google uses Core Web Vitals as part of its page experience signals: LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift) and INP (Interaction to Next Paint). We work on all three, using Google's published thresholds for a "good" score as the reference:

  • LCP (good: 2.5s or less): hero image preload, edge delivery, CDN, image optimization
  • CLS (good: 0.1 or less): explicit image dimensions, reserved space for ads/embeds, font preloading
  • INP (good: 200ms or less): deferred scripts, optimized event handlers, code splitting

Core Web Vitals are one of many signals Google looks at, so speed work doesn't replace good content. But a faster site helps both your visitors and your search visibility — which makes it one of the few improvements with direct UX impact and SEO upside.

Pricing

Speed optimization has no fixed price list, because every site starts from a different place. It's quoted after a short look at your site, and the fixed price is agreed before we start.

  • Audit only: full technical audit + prioritized action plan delivered in PDF. Quoted per project.
  • Audit + implementation (recommended): we audit AND implement the critical optimizations. Quoted per project, timeline agreed in the quote.
  • Larger sites: large e-commerce sites, multi-domain setups, SaaS apps with complex CDN configurations. Quoted per project.

Frequently asked questions

How quickly can you optimize my site?

It depends on the size and complexity of your site. The timeline is agreed in the quote, before any work starts.

Will you change the design?

No. Speed optimization works under the hood — your site looks the same, it just loads faster. We don't touch the design unless you explicitly ask us to.

Do you work with any CMS, e-commerce platform or custom stack?

In most cases, yes. The techniques we use (image optimization, script and CSS loading, caching, fonts) apply to most CMS and e-commerce platforms as well as custom-built sites. If your platform limits what can be changed, we tell you in the quote.

What if my site doesn't improve enough?

We don't promise specific scores, because every site starts from a different place. We measure your key pages before we start and agree the scope in the quote; after the work, we measure again and share the before/after report, so you can see exactly what changed.
