What This Service Solves
Identifying the hurdles
A slow website loses visitors before they convert. Pages that fail Core Web Vitals assessments are penalised in Google search rankings. Security gaps leave the site exposed to compromise. Accessibility failures exclude users and create legal exposure. These are all measurable, fixable problems — but they tend to accumulate quietly until they start affecting revenue or search visibility.
- Page load times above three seconds driving measurable bounce rate increases
- Core Web Vitals failures reducing organic search rankings across key landing pages
- Outdated dependencies and missing security headers leaving the site vulnerable
- Accessibility failures that exclude users and risk compliance issues under WCAG guidelines
Our approach & solution
We run a systematic audit of your site's performance, security posture, and accessibility compliance, produce a prioritised list of issues, and fix them. Every change is benchmarked before and after so you can see exactly what improved. Work is done in your development environment and released through your existing deployment process, not around it.
- Lighthouse and Core Web Vitals audit with scored baseline before any work begins
- Image compression, lazy loading, and script deferral to reduce page weight
- Security header configuration, SSL setup, and dependency vulnerability review
- WCAG 2.1 accessibility audit with fixes to markup, colour contrast, and keyboard navigation
What This Service Includes
Performance Audit
Performance Audit
Full Lighthouse and WebPageTest baseline covering load time, Time to First Byte, Largest Contentful Paint, and Total Blocking Time, with a prioritised fix list.
Image and Asset Optimisation
Image and Asset Optimisation
Convert images to modern formats, apply compression, configure lazy loading, and set correct cache headers to reduce page weight and improve render times.
Script and CSS Optimisation
Script and CSS Optimisation
Identify and defer or remove render-blocking scripts, split code bundles, and inline critical CSS to improve First Contentful Paint and Interaction to Next Paint.
Security Hardening
Security Hardening
Configure security headers, review SSL certificates, audit third-party scripts, and flag outdated dependencies with known vulnerabilities.
Accessibility Audit and Fixes
Accessibility Audit and Fixes
WCAG 2.1 AA audit covering semantic markup, ARIA attributes, colour contrast ratios, keyboard navigation, and focus management, with documented fixes.
Ongoing Monitoring Setup
Ongoing Monitoring Setup
Configure automated performance monitoring and alerting so regressions are caught before they affect rankings or user experience.
How Businesses Use This
Real-world applications across industries — drag or click the cards to explore.
Checkout Page Speed Fix
An online retailer was losing customers at checkout due to a slow payment page. Asset optimisation and script deferral reduced load time by 60 percent, improving conversion rate.
Business Outcomes You Can Expect
Monitoring Prevents Regression
Automated performance monitoring catches new issues introduced by content changes or deployments before they affect user experience or search rankings.
Measurable Before and After
Every fix is benchmarked before work begins and retested after each change, so you have documented evidence of improvement rather than just claims.
Accessible to All Users
WCAG-compliant markup means your site works for users with visual, motor, and cognitive differences, as well as for screen reader and keyboard-only users.
Reduced Security Exposure
A correct security header configuration, up-to-date dependencies, and removal of unnecessary third-party scripts close the most common web security gaps.
Better Search Rankings
Core Web Vitals are a Google ranking signal. Fixing failures in Largest Contentful Paint and Interaction to Next Paint improves organic search position for affected pages.
Faster Load Times
Optimised assets, deferred scripts, and proper caching reduce page weight and improve time to interactive across all device types.
Questions Before We Start
A Few Things Clients Usually Ask
Find answers to common questions about Web Optimization solutions, setup procedures, scoping timelines, and deliverables.
How do you prioritise what to fix first?
We start with the items that have the biggest measurable impact on load time, Core Web Vitals scores, or security risk. For most sites, image optimisation and removing render-blocking scripts deliver the largest performance gains with the least risk. Security fixes like missing headers are quick to apply and high priority regardless of impact on speed. We share the full prioritised list before starting so you can adjust the scope.
Can you optimise a site you did not build?
Yes. We work with existing sites built on any stack — WordPress, Webflow, Next.js, custom builds. We start with a read-only audit before touching any code, so you understand what we are proposing before we make changes.
Will the optimisations break our existing design or functionality?
Optimisations are applied incrementally and tested against the existing design before being released. We do not make structural changes to layouts or remove functionality. Accessibility fixes modify markup to meet standards but do not change visual appearance.
How long does an optimisation project typically take?
A performance audit and the top-priority fixes typically take one to two weeks for a standard marketing site. A full WCAG audit with remediation can take two to four weeks depending on the number of pages and the severity of issues found. We give a time estimate after the initial audit, not before, so it is based on actual findings.
