Find answers to common questions
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.

Fix front-end bottlenecks
Link performance to conversions
Website speed and reliability directly affect revenue, customer acquisition cost (CAC), and lifetime value (LTV) for US-based stores and service companies. The best website performance enhancement strategies United States teams use combine front-end optimisations, server and network improvements, and measurement systems that attribute revenue accurately. These strategies are built for profitable scaling-not vanity metrics-so engineers and growth teams focus on the metrics that move money.
Start with an audit that maps performance to revenue: identify pages with high traffic and high drop-off, then correlate load times with conversion rates. For Shopify or WooCommerce stores this often means prioritising the homepage, category pages, product pages, and checkout. A technical-first approach ties into analytics and tracking so your optimisation efforts show up in clean attribution reports. For an agency-level overview of services that support this approach, see Prebo Digital services.
| Metric | What it shows | Performance range (US ecommerce targets) |
|---|---|---|
| LCP | Perceived load speed | <2.5s (good), 2.5-4s (needs work), >4s (poor) |
| INP | Interaction responsiveness | Lower is better; aim for sub-200ms interactive experiences |
| CLS | Visual stability | <0.1 |
TOF (paid social, search, email) --> Landing page (LCP/CLS) --> Product/Service page (INP, forms) --> Checkout/Conversion (TTFB, server stability) --> Post-purchase analytics
Use server-side event collection or GA4 with Measurement Protocol to reduce attribution loss from ad platforms and browser limitations. Prebo Digital's technical-first approach links performance telemetry to conversion events so you can see how a 1s LCP improvement affects revenue per session. For more context on the agency's approach and team, review About Prebo Digital.
Quick note: in the US, even modest speed gains (0.5-1.0s) on high-traffic pages can reduce bounce and meaningfully lower CAC. Estimated impact depends on conversion baseline and ad spend; use experiments to validate.
Apply a structured framework: Audit → Prioritise → Implement → Measure → Iterate. Below are practical tactics organised by responsibility (frontend, backend, infra, tracking) and examples relevant to Shopify, WooCommerce, and custom platforms used by US brands.
Performance work must link to conversions. Use GA4, server-side tagging via Google Tag Manager server container, or Measurement Protocol to capture conversions with less client-side loss. A clean pipeline also enables A/B tests where the control vs. variant differences are attributed properly to revenue. For integration and tracking build support, see Prebo Digital homepage.
Store profile: $200k monthly revenue, 2.2% conversion rate, $40 average order value. Audit finds homepage LCP = 5s and product pages LCP = 4s. Estimated goal: reduce LCP by 1.5-2.5s across priority pages. Based on typical US ecommerce elasticities, an LCP improvement like this can increase conversion rate by an estimated 5-15% (estimates; validate via A/B tests). If conversion rises 10%, monthly revenue could increase from $200,000 to roughly $220,000 (example estimate-actual results will vary).
