Speed & Core Web Vitals.
Faster stores, and they stay fast.
Performance audits and optimisation for Shopify stores, focused on Core Web Vitals: Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift. We find what is actually slowing the store down, fix it, and set budgets so it stays fixed.
Built for established brands doing $100K+ a year in online sales.
Diagnosis before optimisation.
| Specification | Deliverable | Acceptance |
|---|---|---|
| Performance audit | Field data from Chrome UX Report, lab traces and a ranked list of causes by template. | Prioritised findings |
| Theme optimisation | Image delivery, critical CSS, script loading, fonts and Liquid render cost. | Before/after traces |
| App & script cleanup | Unused app code, duplicate tracking tags and third-party scripts removed or deferred. | No lost functionality |
| Performance budgets | Page weight and script limits checked on every release so regressions are caught early. | Automated checks |
Lab scores are a guide; field data from real visitors is the target. We report both, and we do not chase a score at the cost of features.
The usual suspects.
Slow Shopify stores usually share a few causes: hero images without proper sizing, apps injecting scripts on every page, render-blocking fonts and layout shifts from late-loading content.
We fix the causes in priority order, measure each change, and hand over a short report your team can use to keep new work inside the budget.

From first question to final commit.
Audit
Read the system before rewriting it. Catalogue, code, customers, constraints.
Architect
Make the important decisions early. Data flows, dependencies, delivery plan.
Build
Small, reviewable changes. Clean code, shared context, visible progress.
QA
Test the complete journey. Devices, accessibility, integrations, edge cases.
Ship
Rehearse the launch. Redirects, rollback plan, monitoring, sign-off.
Support
Keep the system healthy. Document, measure, maintain and improve.
Not extras. Acceptance criteria.
A few things, clarified.
Can you guarantee a PageSpeed score?
No honest team can, because scores vary by device, network and page. We commit to finding and fixing the measurable causes, and we report the before and after.
Will you remove our apps?
Only with your agreement. We show which apps cost the most performance and suggest lighter alternatives or better loading strategies.
How long does a speed project take?
An audit typically takes days, not weeks. Fixes are scheduled by impact, with the biggest wins first.
Does speed affect conversion and ads?
Page experience influences how visitors behave, and landing page experience is part of how ad platforms judge your pages. Faster pages remove friction on both fronts.
