Website Speed Optimisation

Your Website Is Slow. It's Costing You Rankings and Revenue. We Fix It.

A 1-second delay in page load time reduces conversions by 7%. Google's Core Web Vitals — LCP, CLS and INP — are confirmed ranking signals that directly affect where your pages appear in search results. Most websites fail one or more Core Web Vitals metrics — and most of those failures are fixable without a full rebuild. Digitly audits, diagnoses and fixes every speed and performance issue on your website — on any platform — improving both your Google rankings and your visitor conversion rate.

Understanding Core Web Vitals

What Are Core Web Vitals — and Why They Affect Both Your Rankings and Revenue

Core Web Vitals are Google's three key page experience metrics — confirmed ranking signals since 2021. They measure three distinct aspects of page performance from a real user's perspective: how fast the main content loads, how visually stable the page is during loading and how quickly it responds to user interaction.

LCP

Largest Contentful Paint

Measures how long it takes for the largest visible element on the page to load.

Good: Under 2.5 seconds
Needs Improvement: 2.5–4.0s
Poor: Over 4.0 seconds

Primary causes: Slow server response, render-blocking resources, unoptimised images.

CLS

Cumulative Layout Shift

Measures the visual stability of your page — how much elements move around as the page loads.

Good: Under 0.1
Needs Improvement: 0.1–0.25
Poor: Over 0.25

Primary causes: Images without dimensions, dynamically injected content, web font loading.

INP

Interaction to Next Paint

Measures how quickly your page responds to user interactions — clicks, taps, key presses.

Good: Under 200ms
Needs Improvement: 200–500ms
Poor: Over 500ms

Primary causes: Heavy JavaScript, third-party scripts, main thread blocking.

Every Speed Issue — Identified, Prioritised and Fixed.

Core Web Vitals Audit

A comprehensive assessment of your website's performance across all three Core Web Vitals metrics — for both mobile and desktop, across your most important pages.

  • PageSpeed Insights assessment — all key pages
  • Chrome UX Report data — real user performance data
  • Field data vs lab data comparison
  • Issue identification — by metric and by severity
  • Prioritised fix list — highest impact first
  • Estimated improvement per fix

LCP Optimisation

Largest Contentful Paint is the most impactful Core Web Vitals metric for most websites. We identify every factor contributing to slow LCP and implement fixes systematically.

  • Server response time improvement — TTFB reduction
  • Render-blocking resource elimination
  • Hero image optimisation — WebP, preload, correct sizing
  • LCP element prioritisation — fetchpriority="high"
  • Font loading optimisation — font-display: swap

CLS Fixes

Cumulative Layout Shift issues are often straightforward to identify but require careful implementation. We locate every shifting element and eliminate the root cause.

  • Image dimension attributes — width and height on all images
  • Ad slot reservation — prevent ad-caused shifts
  • Web font stabilisation — font-display and size-adjust
  • Dynamic content containment — CSS aspect-ratio and min-height
  • Third-party embed containment — YouTube, maps, widgets

INP Optimisation

Interaction to Next Paint issues are the most technically complex Core Web Vitals fixes — requiring JavaScript optimisation and main thread management.

  • JavaScript execution audit — main thread blocking identified
  • Third-party script impact assessment
  • Event handler optimisation
  • Code splitting and lazy loading
  • Web Worker implementation for heavy tasks
Explore INP Fixes

Page Speed Optimisation

Beyond Core Web Vitals — overall page weight, resource loading strategy and server configuration optimisation.

  • Image optimisation — WebP/AVIF conversion, compression, lazy load
  • CSS and JavaScript minification
  • Resource hints — preconnect, preload, prefetch
  • Browser caching configuration
  • CDN setup — Cloudflare
  • HTTP/2 or HTTP/3 configuration

Platform-Specific Speed Fixes

Different platforms have different speed failure patterns. We have specialist experience optimising on every major platform.

  • WordPress — plugin audit, caching, theme code
  • Shopify — app audit, theme optimisation, image pipeline
  • React / Next.js — bundle size, SSR/SSG configuration
  • Lovable / Webflow — asset loading, animation performance
  • Custom builds — full stack audit

How We Work Differently

Why Digitly Speed Fixes Actually Improve Rankings.

Developer Implementation, Not Just Recommendations

Most speed audits produce a report. We produce a report and then implement the fixes — with developers who specialise in Core Web Vitals optimisation across every major platform.

Real User Data Focus

We optimise based on Chrome UX Report (CrUX) field data — real user performance metrics — not just lab-based PageSpeed Insights scores. Real user data is what Google uses for ranking decisions.

All Platforms

WordPress, Shopify, React, Next.js, Webflow, Framer, Lovable and custom builds. Every platform has different speed failure patterns — we know all of them.

Integrated With SEO

Because we're an SEO agency first, every speed fix is evaluated for its ranking impact — not just its PageSpeed score impact. We prioritise fixes that will move your Google rankings.
