Understanding Website Speed and Core Web Vitals

Website speed directly affects user experience, search engine rankings, and conversion rates. Google uses Core Web Vitals as ranking signals, making performance a measurable SEO factor. Our speed test uses the official Google PageSpeed Insights API to give you the same data Google sees.

The Three Core Web Vitals

LCP

Largest Contentful Paint

Measures when the largest visible element (hero image, heading) finishes rendering. Target: under 2.5 seconds.

CLS

Cumulative Layout Shift

Tracks unexpected layout shifts during page load. Caused by images without dimensions or late-loading ads. Target: under 0.1.

INP

Interaction to Next Paint

Measures responsiveness — the delay between a user interaction (click, tap) and the visual response. Target: under 200 milliseconds.

Why Website Speed Matters

Research consistently shows that faster websites convert better. A 1-second delay in page load time reduces conversions by 7% on average. Google confirmed Core Web Vitals as ranking factors in 2021, meaning slow sites are at a measurable disadvantage in search results.

For Irish businesses, server location matters too. Hosting on servers in Ireland or the UK means lower latency for your local audience, directly improving TTFB (Time to First Byte) — the metric that reflects how fast your server responds.

How to Improve Your Score

  • Optimise images

    Use WebP or AVIF formats. Set explicit width and height attributes on every image to prevent layout shift (CLS).

  • Minimise JavaScript

    Remove unused scripts and defer non-critical JavaScript. Heavy JS bundles are the leading cause of poor INP and slow LCP on mobile.

  • Use a fast host

    Your TTFB is limited by server speed. Choose a host with servers close to your audience. Web60 uses Irish data centres for fast local delivery.

  • Enable caching

    Set proper Cache-Control headers for static assets. Browser caching eliminates repeat download time for returning visitors.
