Website speed: why it matters and how to improve it

Speed is not just a technical detail — it directly affects sales and Google visibility. A slow site drives visitors away before they see your offer. Here is why speed matters, what affects it, and how to improve it.

Why does speed matter so much?

Over half of mobile visitors leave a site that loads longer than 3 seconds. Speed is also an official Google ranking factor (Core Web Vitals). A slow site costs twice: lost visitors and worse ranking.

What affects speed?

Common causes: large unoptimized images; excessive JavaScript and plugins; slow hosting; poorly loaded fonts; and third-party scripts (analytics, chat) that block the page. Often a few big images or one heavy script cause most of the slowness.

How to check speed?

Use Google PageSpeed Insights for free. The key metrics are Core Web Vitals: LCP (main content load), INP (responsiveness), CLS (layout shift). Check mobile and desktop separately — mobile is often worse.

How to improve speed?

Compress and convert images to WebP, use modern hosting, defer non-essential scripts (like analytics), reduce JavaScript and load fonts properly. Often just fixing images and deferring analytics improves the score by tens of points.

Speed should be a standard, not an add-on

A good developer builds the site fast from day one, not as a separate "optimization" later. We build with modern tools and test speed before launch. If your current site is slow, a targeted fix is often enough.
