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.

Prioritise by Impact
Improving website accessibility is both a legal and commercial priority for US-based founders, marketing directors, and growth teams. When you focus on how to improve website accessibility through optimization, you reduce friction across the entire funnel, increase usable audience size, and lower abandonment rates-supporting long-term revenue growth rather than vanity metrics. Accessibility optimization also improves SEO, page performance, and attribution accuracy because well-structured HTML and consistent ARIA patterns make analytics more reliable.
| Client | Browser | Server-side | Analytics |
|---|---|---|---|
| User (keyboard/screen reader) | Accessible markup, events, consent banner | Server-side tagging, event validation | GA4 / server-side metrics, accessible funnels |
Mapping tracking like this helps ensure screen reader interactions and keyboard-only navigation generate the same validated conversion events as pointer-based users. For eCommerce stores on Shopify or WooCommerce, this reduces missing conversions and improves MER calculations.
| Stage | Accessibility focus | Business effect (US context) |
|---|---|---|
| TOF (Awareness) | Semantic headings, images with alt text | Improved crawlability and organic traffic quality |
| MOF (Consideration) | Keyboard flows, clear labels, error states | Lower bounce, higher engagement and CLTV |
| BOF (Conversion) | Accessible checkout, ARIA live regions for confirmations | Reduced checkout abandonment and clearer attribution |
Practical optimizations begin with an audit that pairs manual testing (keyboard + screen reader) with automated tooling. Prebo Digital describes a strategy-first approach for technical improvements; learn more about our overall approach on the services page.
For a technical-first implementation that ties accessibility to measurable growth, see how structural improvements feed into analytics and CRO workflows on our homepage. These linkages help product and marketing teams prioritize accessibility fixes that produce the largest revenue impact.
A repeatable accessibility optimization program combines testing, measurement, and governance. Begin with automated scans (e.g., axe-core, Lighthouse) and pair them with manual checks using NVDA/VoiceOver and keyboard-only navigation. Track accessibility defects as part of your backlog and attach estimated revenue impact where possible. For B2B SaaS and eCommerce, include accessibility regression tests in your CI/CD pipeline to prevent new releases from introducing regressions.
Note: Accessibility improvements can reduce customer support costs and protect against avoidable legal risk in the United States. Treat accessibility as part of your product quality rhythm, not a one-off audit.
When you address how to improve website accessibility through optimization, ensure analytics capture the accessibility-enabled conversions. Examples include accessible checkout completions, contact form submissions via keyboard users, or completed video views where captions were required. Implement server-side event validation (server-side tagging) to reduce noise from client-side blockers and to centralize consent handling-this also increases attribution clarity for MER and CAC calculations. Prebo Digital's services include analytics and tracking builds that align with accessibility-aware data collection; learn more on our about page about why technical-first tracking matters.
Example: fixing keyboard trap in checkout might be a 4-hour fix with an estimated 0.5-1.5% improvement in checkout completion. For a $100k/month store, that could translate to an estimated $500-$1,500 monthly revenue gain (figures are estimates for planning only).
