Find answers to common questions
Prebo integrates CRO work with GA4, Google Tag Manager, server-side tracking, and common ecommerce platforms like Shopify and WordPress to ensure accurate event capture and attribution. We also set up ETL or data-layer solutions where needed so test results feed into a single source of truth for decision making.
Common experiments include A/B tests, multivariate tests, funnel experiments, UX and checkout performance optimizations, and technical fixes that reduce friction. Test duration depends on traffic volume and required statistical power but typically ranges from several weeks to a few months per experiment cycle.
We prioritise revenue-per-visitor, conversion rate, average order value, customer acquisition cost (CAC), lifetime value (LTV), and marketing efficiency ratio (MER), alongside statistical significance for experiments. Clean attribution and centralized data pipelines ensure those metrics reflect true business impact rather than platform-reported figures.
CRO is designed to improve conversion efficiency and attribution accuracy, which can increase revenue and profitability when combined with product-market fit and adequate traffic. Outcomes vary by business and depend on test quality, funnel issues identified, and downstream economics, so results are not assured and are measured against revenue-focused KPIs rather than vanity metrics.
CRO is the systematic process of improving a website or funnel to increase revenue per visitor. Prebo Digital uses a technical-first, analytics-driven approach with hypothesis-driven experiments, server-side tracking, and funnel-level optimization focused on measurable revenue outcomes.

Revenue-first CRO
Technical accuracy
Structured growth
Selecting the best website optimization services for e-commerce is about turning visits into predictable revenue. For US-based founders, marketing directors, and growth teams, optimization should reduce CAC, increase average order value (AOV), and lift lifetime value (LTV) - not just inflate traffic numbers. Prebo Digital builds optimization programs that prioritise profitable growth, clean data, and measurable lift across the funnel.
For an overview of how our offerings map to these phases, see our services. Prebo Digital combines technical implementation with experiment design - read about our approach on the homepage to understand how we align tracking and media spend to revenue goals.
A typical initial audit surfaces prioritized fixes and an estimated uplift range. For US DTC and B2B stores, preliminary optimization scopes often include a technical tracking remediation, 4-8 CRO tests in the first 90 days, and performance media alignment to reduce CAC. Cost estimates vary by store complexity; retainers commonly range from $4,000-$12,000/month depending on scope and platform integrations (these are estimates and will vary by project).
The best website optimization services for e-commerce pair CRO with clean analytics. That means GA4 configuration, server-side tracking for resilient conversion capture, and unified reporting so MER and CAC are accurate. For example, switching to server-side event forwarding can recover a meaningful share of lost conversions when browsers block client-side events - improving reported ROAS while providing truer budget decisions.

| Service Tier | Typical Monthly Range | Focus |
|---|---|---|
| Optimization Retainer | $4,000-$8,000 | CRO, tracking, 3-6 tests/month |
| Growth Retainer | $8,000-$12,000+ | CRO + site development + automation |
Engagements are designed to be long enough to run statistically valid tests and iterate. We avoid short-term experiments that produce noisy signals; instead we focus on measurable revenue lift and improved attribution clarity so you know which channels to scale.
Example: A mid-market US Shopify store with $200k/month revenue may start with a $6,000/month retainer aimed at resolving tracking gaps, running high-impact product page tests, and improving checkout throughput. Expected outputs include a prioritized roadmap, implemented tracking, and 2-3 validated lift-producing tests within 90 days (figures are estimates and will vary by store).
