Faster Stores.Higher Revenue.
A 1-second delay in page load time can cost you 7% of conversions. We diagnose, fix, and validate every performance bottleneck in your Magento or Shopify store — with measurable results.
What We Fix
Performance problems are rarely one thing. We work across the full stack — from server config to frontend rendering — to remove every bottleneck.
Server & Infrastructure
TTFB optimisation, Varnish full-page cache configuration, Redis tuning, PHP-FPM pool sizing, CDN setup and cache-control headers — the foundation everything else depends on.
Database & Query Performance
Slow query identification, index optimisation, N+1 query elimination, EAV attribute cleanup, and flat catalogue configuration for large catalogues.
Image & Media Optimisation
WebP conversion, lazy loading, responsive image srcset, CDN delivery, and media gallery optimisation — often the single biggest quick win on image-heavy stores.
JavaScript & CSS Bundles
Bundle analysis, dead code elimination, third-party script auditing, defer/async strategies, and critical CSS extraction — cutting render-blocking resources that delay FCP and LCP.
Core Web Vitals
LCP, CLS, and INP improvements targeted to Google's thresholds — directly impacting SEO ranking, ad Quality Scores, and user experience metrics.
Third-Party Script Management
Audit and governance of analytics, chat, marketing, and tracking scripts — loading them asynchronously, conditionally, or via server-side tagging to eliminate main-thread blocking.
Core Web Vitals & Key Metrics
We optimise to Google's official thresholds — the metrics that directly affect SEO rankings, ad costs, and revenue.
Largest Contentful Paint
How fast the main content loads. Google's primary ranking signal for page experience. Poor LCP is the most common issue on Magento stores with large hero images.
Interaction to Next Paint
How responsive the page feels to user interactions. Replaced FID in March 2024. Heavy JavaScript and third-party scripts are the main culprits.
Cumulative Layout Shift
Visual stability — how much the page shifts as it loads. Banner ads, late-loading fonts, and dynamically injected content are common causes.
Time to First Byte
Server response time before the browser receives any data. Driven by server performance, caching, and network routing. The foundation of all other metrics.
Our Process
A structured audit-first approach — no guesswork, no random fixes, just data-driven improvements with verified results.
Performance Audit
3–5 daysFull audit using Lighthouse, WebPageTest, Chrome UX Report (CrUX), and server-side profiling. We produce a prioritised list of issues ranked by impact and implementation effort.
Infrastructure Assessment
1–2 daysReview of server config, caching layers, CDN setup, PHP version, and database performance. Many of the biggest gains are at the infrastructure level before any code is touched.
Implementation Sprint
1–3 weeksFixes implemented in priority order, each with a defined expected improvement. Server config, code changes, and asset optimisation all delivered with full test coverage and staging validation.
Measurement & Validation
1 weekPost-deployment measurement using the same tools as the audit. We report before/after on every metric and validate against real user data (CrUX) after the changes propagate.
Ongoing Monitoring
OngoingPerformance regressions happen — new extensions, marketing scripts, and deployments all introduce risk. We set up alerting and run quarterly audits to keep scores in the green.
