The business case for speed
In the modern digital landscape, performance isn’t just a technical metric—it’s a critical business driver. Research consistently shows that even a 100-millisecond delay in load time can significantly reduce conversion rates and increase bounce rates.
When your website is fast, users feel in control. They are more likely to stay, explore your services, and ultimately take action. Conversely, a slow site creates friction, erodes trust, and sends potential clients directly to your competitors.
Measuring what matters: Core Web Vitals
To improve your performance, you first need to understand how Google measures it. Core Web Vitals are a set of metrics that focus on user experience:
- Largest Contentful Paint (LCP): Measures loading performance. Aim for 2.5 seconds or less.
- Interaction to Next Paint (INP): Measures responsiveness. Aim for 200 milliseconds or less.
- Cumulative Layout Shift (CLS): Measures visual stability. Aim for 0.1 or less.
Start by measuring your Core Web Vitals in Google PageSpeed Insights before making any changes. You cannot improve what you do not measure.
Quick wins for better performance
If you’re looking for immediate improvements, start with these high-impact areas:
- Optimize images: Use modern formats like WebP or AVIF and ensure images are sized correctly for their containers.
- Minimize main-thread work: Reduce the amount of JavaScript that needs to be parsed and executed on page load.
- Use a CDN: Deliver your assets from a location closer to your users to reduce latency.
