What a slow website really costs your business (and how to fix it)

Slow websites lose visitors, rank lower and waste ad spend. Learn what Core Web Vitals measure, why most small business sites are slow and how to make yours fast.

A slow website doesn't send you an invoice, so its cost is easy to ignore. But every time someone taps your link on a phone, watches a blank screen for a few seconds and hits back, you've lost a customer you already paid to attract — through ads, SEO or your reputation.

Why speed matters more than ever

  • People leave. Google's own research has repeatedly shown that the probability of a mobile visitor leaving rises sharply as load time grows from one to several seconds.
  • Google measures it. Page experience signals, including Core Web Vitals, are part of how Google evaluates pages.
  • Ads cost more. Slow landing pages hurt your ad experience and waste the clicks you pay for.
  • It shapes perception. A sluggish site makes a business feel outdated, even if the work is excellent.

What Core Web Vitals actually measure

Core Web Vitals are three measurements Google uses to judge real user experience:

  • Largest Contentful Paint (LCP) — how quickly the main content appears. Aim for under 2.5 seconds.
  • Interaction to Next Paint (INP) — how quickly the page responds when someone taps or clicks. Aim for under 200 milliseconds.
  • Cumulative Layout Shift (CLS) — how much the layout jumps around while loading. Aim for under 0.1.

You can check your site for free with Google PageSpeed Insights. Look at the mobile results — that's where most local customers are.

Why most small business sites are slow

  1. Heavy page builders that load large amounts of code on every page, whether it's needed or not.
  2. Too many plugins, each adding its own scripts and styles.
  3. Huge, unoptimised images uploaded straight from a camera or phone.
  4. Cheap shared hosting far from the visitors.
  5. Chat widgets, trackers and embeds all loading before the content.

How we build fast sites

We build on Next.js and pre-render pages, so the server doesn't assemble anything when a visitor arrives — the finished page is already waiting on a global network close to them. Images are automatically resized and served in modern formats like AVIF and WebP. Fonts are self-hosted. Scripts load only when they're needed.

“The fastest code is the code you never send. Every script on a page has to earn its place.”

Quick wins you can do today

  • Compress and resize images before uploading — rarely does a website image need to be wider than 2,000 pixels.
  • Remove plugins and widgets you don't actively use.
  • Test your homepage and your most important service page in PageSpeed Insights, on mobile.
  • Make sure your hosting has servers near your customers and uses HTTP/2 or HTTP/3.
