Page Speed Optimisation & Core Web Vitals Services
Every Second You Cut Is Revenue You Keep
Slow pages cost sales and search rankings, and most sites lose both to problems a profiler finds in an afternoon. We measure what actually makes your site slow, fix the real bottlenecks, and prove the result against Core Web Vitals — on real mobile hardware, not a lab score.

Every Second You Cut Is Revenue and Ranking You Keep
Slow pages lose sales and search position, and most sites lose both to problems a profiler finds in an afternoon. We measure what actually makes your site slow, fix the real bottlenecks, and prove the result on real mobile hardware.
Core Web Vitals Are Both an SEO and a Revenue Signal
Google ranks on them and customers abandon without them — the two rarely disagree.
Core Web Vitals are Google’s three field metrics for real-user experience: how fast the main content appears (LCP), how quickly the page responds to input (INP) and how much the layout jumps (CLS). Google uses them as a ranking signal, and each one correlates directly with conversion.
Passing them is therefore two wins at once — better organic visibility and a store that converts more of the traffic it already has. We treat the field metrics as the target, not a lab score that looks good in a report and changes nothing for real users.
- LCP, INP and CLS measured on real users
- SEO ranking and conversion improved together
- Verified on throttled mobile, not just a lab score
Profile First, Fix What the Data Points At
No guesswork, no generic checklist — the traces decide the work.
Most sites lose their speed to a handful of specific causes: render-blocking scripts, oversized images, unbatched third-party tags, missing caching and JavaScript that runs when it should not. We profile your pages, rank the bottlenecks by impact, and fix the ones that actually move the metric.
We work on staging first, test the funnel after every change, and roll out in stages so a regression is caught before your customers see it. You get a before-and-after with real numbers — not a claim that the site is now faster.
- Real profiling, not a generic optimisation list
- Staged rollout with the funnel tested each step
- A measured before-and-after you can verify
Page Speed Optimisation Services
The specific work that turns a red Lighthouse score green — on any platform.
Core Web Vitals Audit
A full field-and-lab audit that identifies exactly what is dragging LCP, INP and CLS down, ranked by the impact of fixing each.
Front-End Optimisation
Critical CSS, deferred JavaScript, font strategy and render-path work that gets meaningful content on screen fast.
Image & Asset Optimisation
Right-sized, modern-format images with explicit dimensions, plus lazy loading — the single biggest win on many sites.
Caching & CDN
Full-page, object and edge caching configured correctly, so repeat visits and global users are served fast.
Third-Party Script Control
Tags, chat widgets and pixels loaded on interaction or deferred, so someone else’s JavaScript stops costing you TBT.
Server & Database Tuning
Query, index and response-time work on the backend, because a fast front end cannot rescue a slow origin.
Layout Stability
Reserved space for images, ads and embeds so nothing jumps as the page loads — CLS driven to near zero.
Monitoring & Reporting
Ongoing field monitoring so a regression is caught in days, not the next time someone checks Search Console.
Keeping the Site Fast as It Grows
Speed is not a one-time job — new features and content erode it.
Performance Budgets
Agreed limits on page weight and script time, so new work has to earn its bytes rather than quietly slow everything down.
Team Guidance
Practical guidance for your developers and marketers so future changes protect the score instead of undoing it.
Regression Monitoring
Automated checks that flag a speed regression when it lands, before it costs rankings or conversions.
Ongoing Optimisation
Periodic re-audits as your catalogue, traffic and third parties change, keeping the field metrics in the green.
Page Speed Questions, Answered
Quick answers on Core Web Vitals, platforms and what a fix is worth.
What are Core Web Vitals and why do they matter?
They are Google’s three field metrics for real-user experience: LCP (how fast the main content appears), INP (how quickly the page responds to input) and CLS (how much the layout jumps). Google uses them as a ranking signal and they correlate directly with conversion.
Passing them is both an SEO and a revenue win, which is why we treat them as the target rather than a vanity score.
Which platforms do you optimise?
Any of them — Magento, Shopify, WooCommerce, WordPress, custom PHP, headless React and more. The techniques differ, but the method is the same: profile first, fix what the data points at, measure the result.
How much faster can you actually make my site?
It depends on the starting point, and we will not promise a number before we have measured. Sites that have never been optimised often see the biggest jumps — render-blocking scripts removed, images right-sized, caching fixed, JavaScript deferred.
You get a before-and-after with real numbers, not a claim.
Will speeding up my site break anything?
Not if it is done carefully. We work on staging first, test the funnel and key pages after every change, and roll out in stages so a regression is caught before your customers see it.
