Your website looks great but loads slowly? You have a problem. Website speed directly impacts your Google ranking, your conversion rate, and your visitors' satisfaction. Every second of loading time costs you customers.
At Alpboost, we build websites that load fast and still look great. In this article, we explain why speed matters and what you can do about it.
Why Loading Time Changes Everything
The numbers are clear:
- 53% of mobile users leave a site that takes longer than 3 seconds to load.
- Every second of delay reduces conversion rates by up to 7%.
- Google uses Core Web Vitals as a ranking factor. Slow sites get demoted.
- Bounce rate increases exponentially with every second of loading time.
For Swiss SMEs, this means a slow website directly costs you revenue. Not only because visitors bounce, but also because Google ranks you lower and you get less organic traffic.
Understanding Core Web Vitals
Google evaluates your website's user experience using three core metrics:
Largest Contentful Paint (LCP)
Measures how long it takes for the largest visible element to load. Target: under 2.5 seconds.
Interaction to Next Paint (INP)
Measures your site's responsiveness. How quickly does it respond to clicks, taps, and keyboard inputs? Target: under 200 milliseconds.
Cumulative Layout Shift (CLS)
Measures visual stability. Do elements shift during loading? This often happens with images or ad banners loading late. Target: under 0.1.
You can check your Core Web Vitals for free using Google PageSpeed Insights or Google Search Console.
Practical Steps for Better Speed
Optimize Images
Images are usually the biggest speed killer:
- Use modern formats like WebP or AVIF
- Compress images to the actually needed dimensions
- Implement lazy loading for images below the visible area
- Use responsive images with the
srcsetattribute
Reduce HTTP Requests
Every file that needs loading costs time:
- Consolidate CSS files
- Minimize JavaScript and load it asynchronously
- Use SVG instead of icon fonts where possible
- Remove unused plugins and scripts
Server and Hosting
A slow server undermines everything else:
- Choose a hosting provider with servers in Switzerland or Europe
- Use a Content Delivery Network (CDN) for static resources
- Enable server-side caching
- Use HTTP/2 or HTTP/3 for faster connections
Leverage Caching
Browser caching ensures returning visitors load the page faster:
- Set cache headers for static resources (images, CSS, JS)
- Implement service workers for offline functionality
- Use cache busting when making changes

Good to know: Test your website speed regularly with tools like Google PageSpeed Insights, GTmetrix, or WebPageTest. Measure not just desktop but especially mobile performance. Most of your visitors come from smartphones. Aim for a PageSpeed score above 90 on both mobile and desktop.
Conclusion: Speed Is Not a Luxury
A fast website is no longer a nice-to-have. It is a prerequisite for good rankings, high conversion rates, and satisfied visitors. The good news: many optimizations are straightforward and deliver immediate results.
Start with a speed test, identify the biggest bottlenecks, and address them step by step. Even small improvements can make a significant difference.
