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.

Audit & Prioritise
Implement Edge & Server-Side
Accessibility & Compliance
Government websites serve high-traffic, mission-critical needs: benefits portals, licensing, public health updates, and FOIA requests. Improving performance reduces bounce rates, lowers support costs, and increases task completion rates for constituents. This guide focuses on measurable, practical steps to accelerate page loads, secure data flows, and preserve accessibility and compliance across US jurisdictions.
Apply a structured plan: Audit → Prioritize → Implement → Measure → Repeat. Start with a Lighthouse/Real User Monitoring (RUM) baseline, map the busiest user tasks (login, forms, file downloads), and address critical paths first. For examples of structured engagement models and retained services, see Prebo Digital services overview and the agency approach on the Prebo Digital homepage.
User Browser → Edge CDN → App Server → Server-side Tracking → Analytics / Data Warehouse → Reporting
Shifting key events to server-side tracking reduces data loss from ad-blockers and consent declines while preserving privacy. For government projects, this also aids in creating auditable logs that meet records retention policies.
| Metric | Target (US Government context) |
|---|---|
| Largest Contentful Paint (LCP) | ≤ 2.5s (real-user median) |
| Total Blocking Time (TBT) | ≤ 200ms |
| Accessibility score | WCAG AA baseline |
Note: Targets above are recommended baselines for public-sector sites in the United States. Use real-user data from the site to set final SLAs and KPIs.
Choose an infrastructure that supports autoscaling, regional cache rules, and edge compute. Implement cache-control headers and use a layered cache (CDN + application cache). For government systems handling sensitive data, keep authenticated APIs behind secure application servers and use token-based short-lived sessions.
Combine RUM, server-side event collection, and batch ETL to a central data store for accurate performance and usage reporting. This reduces attribution gaps caused by browser privacy features. If you want technical examples of tracking-first approaches, see how our agency structures tracking solutions in the About Prebo Digital profile.
Prioritize WCAG AA conformance and follow Section 508 guidance. Accessibility improvements often improve perceived performance by clarifying navigation and reducing DOM complexity. Be mindful of state privacy laws and the California Consumer Privacy Act (CCPA) when implementing analytics; provide clear consent flows and server-side data minimization where required.
A mid-sized state agency portal with 100k monthly users might budget $8,000-$25,000 for an initial performance audit and prioritized remediation (estimates only). Ongoing monitoring and iterative improvements are often managed via monthly retainers or sprint-based contracts. To discuss practical engagements and technical planning, you can request a technical review with team members experienced in government projects.
Measure success with task completion rates, median LCP, TBT, and accessibility scores. Iterate in short cycles: prioritize fixes that reduce time-to-interactive for the most common user journeys. Explore the framework above against your own baselines and see a real-world example by reviewing case approaches on the services overview.
