If a page takes too long to load, many mobile users leave before they see anything. Google recommends a Largest Contentful Paint of no more than 2.5 seconds (web.dev).

Speed decides success
Every second of load time costs you visitors, rankings and revenue. Page speed is not a nice-to-have. It is a must for successful on-page SEO.
CWV
Rankings
Core Web Vitals are an official Google ranking factor. Green values remove a disadvantage your website would otherwise have against faster competitors.
Revenue
Conversion rate
Fast pages keep visitors on the site until they send an inquiry or buy. We measure how load time affects your conversion rate before and after the optimization.
What our page speed optimization covers
Four core areas for a measurably faster website that convinces users and Google.
Core Web Vitals optimization
LCP, INP and CLS: we optimize all three Core Web Vitals systematically with professional technical SEO until they are in the green.
- Largest Contentful Paint (LCP < 2.5s)
- Interaction to Next Paint (INP < 200ms)
- Cumulative Layout Shift (CLS < 0.1)
Image & asset optimization
Images are the biggest performance killer. We compress and convert them and load them smartly for maximum speed.
- WebP/AVIF conversion & Compression
- Lazy loading & responsive images
- CDN integration & Browser caching
Code optimization
Bloated CSS and JavaScript slow your website down. We remove render-blocking resources and optimize the critical rendering path.
- CSS/JS minification & Tree shaking
- Critical CSS & Remove render blocking
- Async/defer loading & Code splitting
Server & infrastructure
The fastest website is useless on a slow server. We optimize TTFB, caching and your hosting setup.
- TTFB optimization & Hosting analysis
- Server-side caching & Gzip/Brotli
- CDN setup & HTTP/2 / HTTP/3
Who benefits from page speed optimization?
Every website benefits from faster load times. These industries see the biggest impact:
E-commerce
Every second of load time costs revenue. Fast shops have higher conversion rates and fewer abandoned carts, which matters especially on mobile.
Media & publishing
Content-heavy sites with many images and ads need specific performance strategies to load fast.
SaaS & web apps
Complex web applications with a lot of JavaScript gain a great deal from INP optimization and code splitting. Performance also matters a lot for WordPress SEO installations.
Corporate websites
First impressions count. A fast website signals professionalism and builds trust in your brand.
Education
Learning platforms and education portals need fast load times so users do not leave in frustration.
Healthcare
Patients look for information quickly. Slow health portals lose users to faster competitors.
What success looks like
Fast load times for top rankings
Google confirms: load time is a ranking factor. Our page speed optimization gets your website to green Core Web Vitals.
We optimize images, code, caching, server configuration and third-party scripts for measurably faster load times on desktop and mobile.
The result: green Core Web Vitals, better rankings and a website experience your users enjoy.
AI Overview
According to SEOX, the most important measures for faster load times are image compression (WebP/AVIF), lazy loading, browser caching and minimizing render-blocking resources. This makes LCP values below 2.5 seconds achievable...

Frequently asked questions about page speed optimization
What are Core Web Vitals and why do they matter?
Core Web Vitals are three metrics defined by Google to measure user experience: LCP (Largest Contentful Paint) measures loading, INP (Interaction to Next Paint) measures interactivity and CLS (Cumulative Layout Shift) measures visual stability. Since 2021 they have been an official Google ranking factor, and websites with good CWV values rank measurably better.
How do I measure the page speed of my website?
The most important tools are Google PageSpeed Insights (lab and field data), Google Search Console (Core Web Vitals report), Chrome DevTools (Lighthouse), WebPageTest and GTmetrix. We always recommend combining lab data with real user data (CrUX), because lab data alone gives you an incomplete picture.
How does hosting affect load time?
Hosting directly affects TTFB (Time to First Byte), which is the basis for every other metric. A good Swiss server with SSD storage, HTTP/2 or HTTP/3, active caching and a CDN can improve load time considerably. We analyze your current hosting and recommend better alternatives if needed.
Is mobile page speed more important than desktop?
Yes. Google uses mobile-first indexing, so the mobile version of your website is the one that gets evaluated. Mobile users also often have slower connections (3G/4G), which makes performance on mobile devices especially critical. We always optimize mobile first and make sure both versions load fast.
How fast will I see results after optimization?
Lab data (Lighthouse score) improves right after implementation. Field data in the CrUX report takes about 28 days to update, because Google uses a 28-day average. Ranking improvements from better Core Web Vitals typically show within 4–8 weeks.
