On Shopify Plus, that's a mix of qualitative research (session replay, customer interviews, support log mining), quantitative analysis (funnel breakdowns in GA4 and Shopify reports), and a structured experimentation program that ships changes only when they earn their place. Mejix runs CRO as engineering, not opinions. Every recommendation is tied to a measurable hypothesis with a defined success metric. We obsess over the unglamorous side of conversion — page speed and Core Web Vitals, broken cross-sell logic, hidden friction in the cart and checkout, and trust signals that aren't doing their job — because that's where most of the lift hides. Typical engagements combine an initial diagnostic audit with an ongoing program of testing, theme refinements, and Checkout Extensibility tweaks. The output isn't a slide deck — it's measurable revenue lift, validated against a holdout, with the experiment log to prove it. What's included ## Concrete deliverables Every engagement ships a defined scope. No vague promises — these are the artifacts and outcomes you can expect. ### Diagnostic audit Quantitative funnel breakdown plus qualitative session-replay analysis to surface the highest-leverage opportunities first. ### Performance & Core Web Vitals Image, font, and third-party script audits; LCP, INP, and CLS work; real-user metric monitoring. ### Funnel & UX refinements PDP, cart, and checkout improvements grounded in real customer behaviour, not opinion. ### A/B testing program Hypothesis library, prioritisation matrix, and a tested A/B framework (Convert, VWO, Shopify-native) with proper sample sizing. ### Personalisation Segment-based experiences for VIPs, returning customers, B2B accounts, and traffic source — without page-speed cost. ### Reporting & decision log Monthly performance reports and an experiment log so leadership sees the cumulative impact, not just last week's win. How it works ## A predictable delivery process The same sequence we run on every engagement, refined across enterprise Shopify Plus projects. 1. 01 ### Diagnostic & opportunity map Two weeks of audit, session replay, and analytics work that produces a ranked list of opportunities and a baseline. 2. 02 ### Quick wins & speed work Ship the no-test-required improvements first — performance, broken flows, obvious friction. 3. 03 ### Structured experimentation Hypothesis-driven A/B tests with proper sample sizing, holdouts, and a written decision per result. 4. 04 ### Quarterly review & roadmap Cumulative impact review, refreshed roadmap, and a recalibrated hypothesis library every quarter.
