// Why This Matters

A Slow Site Is Losing You Customers Right Now

Most website owners find out their site is slow the hard way — through falling conversion rates or a Google Search Console warning — rather than by actually measuring it. Research consistently shows that as load time increases past 2-3 seconds, bounce rate climbs sharply. Visitors don't file a complaint. They just leave.

We see this constantly through our free website audits: sites built on decent platforms, dragged down by a handful of fixable problems nobody ever addressed — often because the original developer wasn't around to ask, or the fix required more technical depth than a page builder plugin can offer.

  • Real diagnosis before any work starts — no guessing
  • Fixed-price quote once we know the actual cause
  • Before/after performance report you can keep
  • Honest advice if a rebuild beats a patch job

// What We Check and Fix

Every Common Cause of a Slow Website

We work through a structured checklist rather than guessing — most slow sites share the same handful of problems.

Image Compression & Formats

Oversized, uncompressed images are the single most common cause of slow load times. We convert to WebP/AVIF, resize correctly for each breakpoint, and set up lazy loading below the fold.

Render-Blocking CSS & JS

We inline critical CSS, defer non-essential stylesheets, and split or defer JavaScript so the browser can paint your page before it finishes downloading everything.

Third-Party Script Audit

Chat widgets, tracking pixels, review plugins and page builders each add their own JavaScript payload. We identify which ones are actually earning their keep and remove or defer the rest.

Core Web Vitals

We measure and fix the three metrics Google uses to score real-world experience: Largest Contentful Paint, Cumulative Layout Shift and Interaction to Next Paint.

Hosting & Server Response

Sometimes the site is fine and the hosting isn't — a slow Time to First Byte usually points to underpowered shared hosting. We'll tell you honestly if that's your bottleneck.

Before/After Report

You get a plain-English report showing exactly what changed and the measured before/after difference — not just a "job done" email.

// Common Questions

Website Speed Optimisation FAQs

It depends what's actually wrong, which is why we start with a free audit rather than quoting blind. Once we know whether the problem is images, render-blocking code, hosting, or a bloated theme, we give you a fixed price for the fix — no hourly billing, no surprises.

We optimise WordPress, Shopify, Squarespace and custom-built sites regardless of who built them originally. Some platforms have harder ceilings than others — a heavily plugin-loaded WordPress site or a template-based Shopify theme will only get so fast before a rebuild is the honest answer, and we'll tell you if that's the case.

In our experience across 100+ projects, the same handful of causes account for most slow sites: unoptimised images (the single biggest offender), render-blocking CSS and JavaScript, too many third-party scripts (chat widgets, tracking pixels, page builders), and cheap shared hosting under real traffic load.

Page speed and Core Web Vitals are a confirmed Google ranking factor, and a faster site reduces bounce rate and improves conversion regardless of SEO impact. We don't promise a specific ranking jump — nobody honestly can — but slow sites are working against themselves on both fronts.
