Website speed and user experience are no longer optional. Google now measures how users experience your website through Core Web Vitals, a set of performance metrics that directly impact rankings, conversions, and trust.
For businesses in Switzerland and worldwide, improving Core Web Vitals means:
1. What Are Core Web Vitals?
Core Web Vitals are Google’s way of measuring real user experience on your website. They focus on how fast your site loads, how quickly users can interact, and how stable the page feels.
Google uses three main metrics:
Largest Contentful Paint (LCP)
Interaction to Next Paint (INP)
Cumulative Layout Shift (CLS)
These metrics apply to both desktop and mobile, with mobile performance being the priority.
2. Largest Contentful Paint (LCP): Loading Speed
LCP measures how long it takes for the largest visible element on a page to load, such as a hero image or headline.
Common LCP issues:
Large images
Slow hosting
Render-blocking CSS
Too many scripts
How to improve LCP:
Optimize and compress images
Use fast hosting
Enable caching
Use a Content Delivery Network (CDN)
For Swiss businesses serving international users, CDNs are critical.
3. Interaction to Next Paint (INP): Responsiveness
INP measures how quickly your website responds to user interactions like clicks or taps.
Causes of poor INP:
How to improve INP:
Reduce JavaScript execution
Remove unnecessary plugins
Use lightweight themes
Delay non-critical scripts
Fast interaction builds trust and improves conversion rates.
4. Cumulative Layout Shift (CLS): Visual Stability
Heavy JavaScript
Unoptimized themes
Too many plugins
CLS measures how much content shifts while the page loads.
Common CLS problems:
Images without size attributes
Late-loading ads
Font swapping
How to improve CLS:
Set image and video dimensions
Reserve space for ads
Use system fonts or preload custom fonts
Stable pages feel professional and reliable.
