SPEED OPTIMISATION

Your site is losing customers
to a slow load time

A 1-second delay in page load drops conversions by 7%. We diagnose and fix the exact reasons your WordPress or WooCommerce site is slow: then deliver a verified 90+ PageSpeed score and a faster site your visitors actually stay on.

We start with a deep technical audit

Before we touch a single setting, we run a full technical audit of your site: not just PageSpeed Insights, but GTmetrix, WebPageTest, real device testing, and a manual code review. We find the exact bottlenecks dragging your score down.

Every site is different. A plugin conflict, a poorly coded theme, uncompressed images, render-blocking scripts, or a slow server: we identify the real cause and fix it, not just the surface symptoms.

Speed Audit

PageSpeed Insights, GTmetrix, WebPageTest, and real device testing across mobile and desktop. We identify every slow point with actual data.

Code Review

Manual review of your theme code, plugin load order, database queries, and server configuration. Most speed problems are in code, not settings.

Optimisation

We apply every fix: images, caching, CDN, scripts, fonts, database: in a staging environment and verify the score before pushing to production.

Verified Delivery

You receive a before/after report with scores, screenshots, and a list of every fix applied. The 90+ score is confirmed live, not promised.

Every issue that slows WordPress down

Every item below is in scope: we fix what your site actually needs, not a generic checklist.

Image Optimisation

Bulk convert to WebP, apply lazy loading, correct image dimensions, and remove metadata. Images are typically the single largest load-time factor on WordPress sites.

Caching Setup

Page caching, object caching, browser caching headers, and database query caching all configured correctly for your hosting environment.

CDN Configuration

Cloudflare or equivalent CDN set up to serve static assets from edge locations close to your visitors: critical for sites with international audiences.

CSS and JS Minification

Minify, bundle, and defer non-critical CSS and JavaScript. Eliminate render-blocking resources that delay the first paint of your page.

Database Optimisation

Clean post revisions, spam comments, transients, and orphaned data. Optimise database tables and add missing indexes for faster query performance.

Plugin Audit

Identify and remove plugins that add unnecessary scripts, styles, or database queries on pages where they are not being used. Plugin bloat is a very common cause of slow WordPress sites.

Font Optimisation

Self-host Google Fonts, add font-display:swap, preload critical fonts, and eliminate FOUT (flash of unstyled text) that shifts layout on load.

Core Web Vitals Fix

LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift): all three Google ranking signals diagnosed and fixed.

GZIP / Brotli Compression

Enable server-level compression on text assets: HTML, CSS, and JS. Reduces transfer size by up to 70% with zero change to how the site looks or works.

HTTP/2 and Server Config

Verify HTTP/2 is active (required for request multiplexing), check server response time, and recommend or configure hosting upgrades where needed.

Third-Party Script Audit

Review every external script: chat widgets, analytics, pixels, review apps: and load them async or defer to keep them off the critical render path.

Before/After Report

Full written report with your before and after scores, screenshots, and a complete list of every fix applied: so you know exactly what was done and why.

The three signals Google actually uses to rank pages

Core Web Vitals are not optional: they are live Google ranking factors and they directly affect how visitors experience your site. We fix all three.

LCP Target under 2.5s

Largest Contentful Paint

How long before the main content: the hero image, heading, or above-the-fold block: is fully visible to the visitor. The most common fix is image optimisation, preloading, and eliminating render-blocking resources.

We fix: Hero image optimisation, preload hints, server response time, render-blocking scripts
INP Target under 200ms

Interaction to Next Paint

How quickly the page responds when a visitor clicks a button, taps a link, or interacts with any element. Replaced FID in March 2024 and is now measured across the full session, not just the first interaction.

We fix: Long JavaScript tasks, main thread blocking, third-party script deferral, plugin conflicts
CLS Target under 0.1

Cumulative Layout Shift

How much the page layout jumps around as it loads: images without dimensions, font swaps, late-loading ads or banners. A high CLS makes the page feel unstable and causes visitors to click the wrong thing.

We fix: Image dimension attributes, font-display:swap, reserved space for embeds, ad slot sizing

90+ PageSpeed or we keep working for free

We do not just aim for 90+: we guarantee it. Before we hand back your site, the score is confirmed live with a screenshot. If it is below 90+ on your hosting, we keep optimising at no extra charge until it hits the target.

This is possible because we run a full technical audit before we start. We know what we will find, and we know how to fix it. We do not take on projects we cannot deliver on.

Speed optimisation questions answered

Have a specific question about your site? Get in touch and we will answer it directly.

Will speed optimisation change the design of my site?

No. We optimise the code and configuration behind your site: images, scripts, caching, and server settings. Your design, content, and functionality remain exactly the same. We do all work on a staging copy first and only push to production after you approve the results.

My site scores well on desktop but badly on mobile. Can you fix that?

Yes. Mobile and desktop scores are measured separately and the causes of a low mobile score are often different: image sizes, JavaScript execution, and render-blocking resources all have more impact on mobile. We fix both.

What is the difference between PageSpeed score and actual page speed?

PageSpeed Insights gives a score from 0 to 100 based on a set of weighted metrics. Actual load time (how long before the page is usable) is related but not the same thing. We target both: a high score and a fast real-world experience, not just one or the other.

Do I need to change my hosting?

Not always. Many speed issues are in the theme, plugins, or site configuration and can be fixed without moving hosts. If your hosting is genuinely too slow for your traffic, we will flag it in the audit with specific recommendations: but we do not require a hosting change to do the work.

Does this work on WooCommerce stores too?

Yes. WooCommerce adds complexity: cart fragments, dynamic pages that cannot be fully cached, and payment scripts: but we handle all of it. WooCommerce speed optimisation requires specific techniques and we are familiar with all of them.

How long does a speed optimisation project take?

Most projects complete in 3 to 7 days. We will give you a specific timeline after the free audit, based on what we find.

What if my score drops again after you fix it?

If you install a heavy plugin or change your hosting after we finish, the score may drop: that is outside our control. For changes we make, if the score falls below 90+ within 30 days and the cause is our work, we fix it at no charge.

Can you fix Core Web Vitals failures in Google Search Console?

Yes. Google Search Console reports Core Web Vitals failures based on real user data, which takes a few weeks to update after fixes are applied. We fix the underlying technical issues and the Search Console data will update as Google recrawls your pages.

WordPress Speed Optimisation: Core Web Vitals Fix and 90+ PageSpeed Score

A slow WordPress site costs you in three ways: lower Google rankings, higher bounce rates, and fewer conversions. Google has confirmed Core Web Vitals as a ranking signal, which means a site that scores poorly on LCP, INP, and CLS is being actively held back in search results compared to faster competitors. We fix all three signals on WordPress and WooCommerce sites without rebuilding them.

Most WordPress speed problems come from the same sources: uncompressed images, too many plugins loading scripts on pages where they are not used, no caching, synchronous font loading, and render-blocking scripts. We identify the exact problems on your site through a thorough audit before starting work, and we fix them on a staging environment before touching your live site.

WordPress speed optimisation without rebuilding your site

Many agencies tell clients their site needs to be rebuilt to fix its speed. In most cases that is not true. Speed problems are almost always fixable through image optimisation, caching configuration, script deferral, and database cleanup: none of which require changing your design or moving to a different theme. We have taken sites from PageSpeed 34 to PageSpeed 91 on the same theme, same hosting, same content: just better configuration and cleaner code.

We work with WordPress and WooCommerce sites for clients in the US, UK, Australia, Canada and India. Every project includes a free pre-work audit, a staging-first process, a confirmed 90+ score at delivery, and a full before/after written report documenting every fix applied.
