Why fast websites win: performance and SEO basics

The matmad team·

Website speed is one of the few things that improves rankings and conversions at the same time. Visitors are impatient, and Google measures the experience your site delivers. Slow sites lose on both counts.

Speed affects revenue directly

Studies consistently show conversions fall as load times rise. A slow site quietly turns away the visitors you worked hard to attract — every extra second costs you enquiries.

Google measures Core Web Vitals

  • LCP — how fast the main content appears (aim under 2.5s)
  • INP — how quickly the page responds to interaction (under 200ms)
  • CLS — visual stability, with no jumping layout (under 0.1)

What makes a site fast

  • Optimised, modern image formats and lazy loading
  • Minimal, efficient JavaScript
  • Static or server-rendered pages served quickly
  • Good hosting and caching

Fast by default

We build on a modern, performance-first stack, so speed is engineered in rather than bolted on. Fast Core Web Vitals come as standard on every site we ship.
