How Website Speed Affects SEO and User Experience

With Core Web Vitals, Google measurably assesses how fast and stable a page loads. Slow pages rank worse – especially on mobile, where most traffic happens.

Speed is not an end in itself: it directly influences whether users stay or bounce.

Studies keep showing the same relationship: the longer the load time, the higher the bounce rate and the lower the conversion. A fast site earns more from the same traffic.

This is decisive for companies running ads – every lost second makes paid clicks more expensive.

The biggest levers are usually optimised images, less render-blocking JavaScript, sensible caching and a lean, modern frontend. A professional setup addresses these from the start.

Measure before and after every change – that is the only way to make the effect visible and provable.
