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.

Retainer & Reporting
If you searched "get a quote for website performance enhancement services United States", you likely need a clear cost estimate and scope for uplift in site speed, Core Web Vitals, server-side tracking, and conversion flow improvements. Website performance work is revenue-focused: faster pages and reliable tracking directly reduce customer acquisition cost (CAC) and improve conversion rate (CRO), which increases lifetime value (LTV) per visitor.
Typical engagement sizes vary: a focused audit and remediation plan often ranges from $3,000-$10,000, while a monthly retainer for ongoing performance engineering and CRO can run from $4,000-$12,000 per month depending on traffic volume and complexity. These ranges are estimates for United States-based eCommerce and B2B sites and will be refined during discovery.
A quote should be based on measurable opportunity, not hours. Prebo Digital scopes around revenue impact: we estimate potential incremental monthly revenue and CAC reduction before recommending investments. That means an initial audit that ties performance wins to $ outcomes on your Shopify, WooCommerce, or custom stack.
Start with a short technical discovery so we can produce a precise quote. Learn about our overall services and approach on the services overview page: Services Overview. For context on how we combine analytics and growth systems, see our homepage for examples of integrated work: Prebo Digital.
Quick example: improving median Largest Contentful Paint (LCP) from 4.2s to 2.2s on a US Shopify store with $150,000 monthly revenue can increase monthly checkout conversions by a measurable percent; even a 3% lift equals an additional ~$4,500/month before attribution. Exact outcomes depend on traffic mix and funnel.
| Included | Excluded (commonly billed separately) |
|---|---|
| Performance audit, prioritized issue list, CDN & caching config, Core Web Vitals fixes | Major theme redesigns, third-party paid integrations, hosting fees |
| Server-side tracking and tag management (GA4, GTM) | Paid A/B testing platforms (if requested), paid plugin licenses |
| Conversion funnel review and quick CRO tests | Ongoing creative production or deep UX redesigns |
We run lab and field tests, review Core Web Vitals, and map the funnel (TOF → MOF → BOF) to identify where speed and tracking issues leak revenue. This discovery produces a scoped proposal with estimated $ upside and timeline.
Implementation focuses on high-impact items first: critical CSS, image delivery (modern formats + responsive sizes), lazy-loading, CDN and cache rules, and server-side tracking using GA4 and GTM. For Shopify or WooCommerce stores we align changes with platform constraints and app/plugin ecosystems.
We validate improvements with real-user metrics from US markets and device segments, and run conversion experiments when changes touch funnel steps. Read about our agency background and technical-first approach on the about page: About Prebo Digital.
After fixes, we implement monitoring and alerting for regressions and automate performance checks in your CI/CD or deployment pipeline. Ongoing retainers include monthly performance reviews and optimization sprints, designed to reduce CAC over time.
Our reports tie performance improvements to revenue metrics (MER, CAC, conversion rates) and include attribution clarity to avoid over-relying on platform-reported conversions. If you want a tailored quote, request a discovery that includes a scoped cost estimate and timeline: Request a discovery.
