We build Shopify and WooCommerce sites with a technical-first approach that combines user experience, conversion-rate optimisation, and back-end analytics to support revenue-focused outcomes and scalable growth.
We implement GA4, Google Tag Manager, server-side tracking, and data pipeline practices (ETL) to reduce signal loss and align marketing metrics with actual revenue and customer journeys.
CRO is integrated throughout design and development: we use quantitative analytics and A/B testing to identify friction, iterate page layouts and copy, and prioritise changes that increase revenue per visitor.
Design decisions are evaluated by measurable impacts on conversion rate, average order value, customer lifetime value, and acquisition cost, with priorities set to improve profitability rather than vanity metrics.
We handle both new builds and redesigns as well as migrations, performance optimisation, and technical debt remediation while preserving or improving revenue-critical tracking and integrations.

Audit-to-scale process
Page speed is a revenue problem, not just a technical one. Our affordable website speed optimization services in New York focus on measurable impact: faster load times that lift conversion rates, reduce bounce, and improve ad efficiency across Google Ads, Meta, and programmatic channels. For US-based Shopify and WooCommerce stores, an improvement in load time is often correlated with higher average order value and lower customer acquisition cost (CAC); estimates used here are illustrative and results will vary by site and vertical.
We pair a technical-first toolkit with funnel-focused goals: Core Web Vitals, server-side caching, image and asset delivery improvements, and front-end code optimization. If you want a concise overview of how this fits into a broader growth stack, see our services overview here, or learn about our agency approach on the homepage Prebo Digital.
Practical US example: a Shopify store with $150 average order value that improves average page load by 1.2s might see a conservative 3-8% conversion lift (estimate). For a site doing $50,000/month, a 5% lift is an additional $2,500/month in revenue before ad spend changes.
| Metric | Target | Why it matters |
|---|---|---|
| Largest Contentful Paint (LCP) | < 2.5s | Improves perceived load and ad quality scores. |
| Cumulative Layout Shift (CLS) | < 0.1 | Reduces accidental clicks and checkout errors. |
| First Contentful Paint (FCP) | < 1.8s | Improves initial engagement and perceived speed. |
Our work is practical and platform-aware: optimizations for Shopify differ from WordPress/WooCommerce. Typical tasks include optimizing critical render paths, implementing asset and image CDNs, reducing third-party script impact, and configuring server-side caching and edge rules. For a broader overview of our capabilities across paid media, CRO, and tracking that complement speed work, review our services page here.
1. Audit: a prioritized performance audit (Lighthouse, WebPageTest, field data) that maps issues to revenue impact. Audits include a performance budget and a rollout plan for Shopify, WooCommerce, or custom stacks.
2. Build: technical fixes (server settings, image formats, font loading, JS splitting) are implemented with change scopes and rollback plans. For Shopify stores we follow theme-safe patterns to avoid breaking apps; for WordPress we recommend server and plugin configurations that are maintenance-friendly.
3. Test: A/B or holdout experiments validate real conversion lift. We track results using clean analytics setups (GA4 + server-side when appropriate) so performance wins are attributed correctly across ads and organic channels. Learn more about our agency background and approach on the about page About Prebo Digital.
Our affordable packages are built for growing US brands: you can choose a single sprint to fix immediate bottlenecks or a monthly retainer for sustained performance and experimentation. Retainers include ongoing performance regression checks, Core Web Vitals monitoring, and incremental tests designed to reduce CAC over time. If you’d like to discuss schedule and scope, you can request a growth audit via our contact page here.
Example US scenario: a mid-market DTC brand on Shopify running $120k/month in ad spend may allocate a $3k-$7k monthly retainer for continuous speed and CRO work, with early wins often seen within the first 30-60 days. These figures are illustrative and should be validated during an audit.
We emphasize clear attribution: server-side event forwarding, GA4 configuration, and cross-channel reporting ensure speed wins are reflected in revenue metrics, not just lab scores. That clarity helps reduce wasted ad spend and improves MER and CAC calculations for US ad platforms.
