Looking for a CRO agency in London?
Lazige offers direct consultant-led delivery for London and UK teams. Agree a focused audit, an implementation project or ongoing experimentation support. Your team can retain engineering ownership, or include implementation in our scope.
If traffic is too low for a useful A/B test, start with tracking quality, usability research and clear journey problems. We assess feasibility before promising a testing cadence.
How traffic and sample size affect an A/B testmethodology
A/B testing background & methodology.
We've built and executed experimentation programs for B2B SaaS platforms, e-commerce sites, and high-traffic applications. Our approach combines statistical rigor with practical implementation, ensuring experiments deliver actionable insights, not just numbers.
Core Methodology
- •Signal-first discovery: Map friction points using session replays, product analytics, and support transcripts before designing experiments
- •Statistical guardrails: Proper sample size calculations, significance testing, confidence intervals, and automated analysis that flags invalid results
- •Implementation sprints: Lightweight ES5-compatible variations that don't derail roadmap work, with feature flags for safe rollouts
- •Shared analytics dashboards: Real-time experiment status, uplift ranges, and confidence intervals visible to marketing, product, and leadership
Tools & Platforms
- Optimizely Edge & Web: Client-side and server-side experimentation
- Custom experimentation frameworks: Full-stack platforms with feature flags, A/B tests, and multivariate tests
- Analytics integrations: Google Analytics 4, Mixpanel, Looker dashboards
- UX research tools: Session replays, heatmaps, funnel analysis, user interviews
pricing and scope
Choose the right starting point.
A funnel audit identifies and prioritises opportunities. An implementation project turns selected hypotheses into working variations. Ongoing support adds experiment planning, QA and results analysis across successive cycles.
Bring your monthly traffic, current conversion rate, analytics setup and the journey you want to improve. We use these to agree a realistic scope and budget.
