Service 11 / 11
Core Web Vitals, Lighthouse and real-user audits that turn a slow site into a fast one — with measurable gains in conversion and rankings.
Overview
What you get.
- Lighthouse 95+
- CWV pass
- Real user gains
Speed is a revenue lever: slower pages lose visitors, rankings and sales. We measure with both lab tools (Lighthouse) and field data (CrUX, RUM) so we fix what real users actually experience.
Each fix is prioritised by impact versus effort and verified with before/after metrics — no guesswork and no vanity scores.
Performance work fails when it's treated as a score chase. A perfect lab score on a fast laptop means little if your real customers are on mid-range phones on patchy networks. We prioritise field data and your most valuable pages.
We also address the usual culprits that engineering alone can't fix — heavy marketing tags, unoptimised hero media and third-party widgets — and give your team practical guidelines to keep them in check.
Why it matters
The problem we solve.
Speed influences conversion
Faster pages keep visitors engaged and reduce bounce, particularly on mobile.
Core Web Vitals affect search
Google uses real-user experience signals as part of page experience.
Slow sites cost more to run
Heavy pages and inefficient queries raise bandwidth and server bills.
Accessibility and speed overlap
Lean, semantic pages perform better for people on slow devices and connections.
Scope of work
What’s included.
Performance audit
Lighthouse, WebPageTest, CrUX and RUM review with a ranked fix list.
LCP / INP / CLS fixes

Glossary
Terms we use.
- LCP
- Largest Contentful Paint — how fast the main content appears (target < 2.5 s).
- INP
- Interaction to Next Paint — responsiveness to input (target < 200 ms).
- CLS
- Cumulative Layout Shift — visual stability (target < 0.1).
- TTFB
- Time to first byte — server and network response time.
- Critical rendering path
- The steps the browser takes to display the first pixels.
- Performance budget
- A limit on page weight or timings enforced in CI.
- Lazy loading
- Delaying off-screen images and scripts until they're needed.
- Render-blocking resource
- CSS or JS that prevents the browser from displaying content until it loads.
FAQ
Common questions.
What scores can you guarantee?
We target Lighthouse 95+ and passing Core Web Vitals on key templates, but real results depend on your stack and third-party scripts — we set targets after the audit.
Will you rebuild the site?
Rarely. Most gains come from targeted fixes; we only recommend a rebuild if the architecture is the bottleneck.
How soon will rankings improve?
Field data takes about 28 days to update in CrUX; ranking effects follow over the following weeks.
What deliverables do I get?
An audit report with findings and priorities, implemented fixes, before/after metrics and guidance to keep scores healthy.
Do third-party scripts matter?
Hugely. Tag managers, chat widgets and trackers are often the biggest cost; we audit, defer or replace the worst offenders.
Can you optimise a site you didn't build?
Yes, across most stacks — Next.js, React, WordPress, Shopify and custom builds.
Working together
How we engage.
Fixed-scope project
A defined scope, timeline and price agreed after discovery. Best for launches and rebuilds with clear requirements.
Monthly retainer
A dedicated block of senior time each month for continuous delivery, iteration and support.
Audit & advisory
A short, focused engagement that reviews what you have and hands you a prioritised plan to act on.
What to expect
Kickoff
A 45–60 minute call to understand goals, audience, constraints and timeline.
Written proposal
Scope, milestones, deliverables and pricing within a few working days of the call.
Weekly rhythm
A short demo and written update every week so there are never surprises.
Your input
One decision-maker, timely feedback and access to brand assets, content and accounts.
