A/B Testing Background & Methodology

I've built and executed experimentation programs for B2B SaaS platforms, e-commerce sites, and high-traffic applications. My 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

Quantitative Results: Conversion Lifts

18% Trial-to-Paid Lift (B2B SaaS)

Starting point: 12.4% trial-to-paid conversion rate. Experiments were run ad hoc, results inconsistently documented.

Approach: Established weekly experiment cadence, refactored trial onboarding flow, instrumented funnels with activation metrics. Key experiments included value framing overhaul, guided setup checklist, and pricing preview transparency.

Results:

  • • 18% lift in trial-to-paid conversion (12.4% → 14.6%)
  • • Sustained over three consecutive quarters
  • • 27% faster experiment turnaround (11 days → 8 days)
  • • 60% adoption of experimentation playbook templates across teams

35% Conversion Increase (SaaS Platform)

Challenge: Strong product-market fit but struggling conversion rates during signup and onboarding.

Approach: Comprehensive optimization of landing page messaging, signup flow design, onboarding experience, and micro-interactions. Focused on first-value delivery and reducing friction.

Results:

  • • 35% increase in conversion rate
  • • Significantly improved growth trajectory
  • • Better lead quality through optimized messaging

4× Increase in Experiments Shipped

Context: Product team making opinion-driven decisions. Experiments ad hoc without statistical rigor.

Approach: Built full-stack experimentation platform with statistical guardrails, automated reporting, and analytics integrations. Established experiment lifecycle management and team training.

Results:

  • • 4× increase in experiments shipped (2 → 8 per month)
  • • 60% reduction in time from hypothesis to launch (3 weeks → 1 week)
  • • 45% improvement in experiment win rate (22% → 32%)
  • • Zero statistical errors after guardrail implementation

Frequently Asked Questions

A CRO consultant analyzes your website or application to identify friction points, design experiments to test improvements, and implement data-driven changes that increase conversion rates. I combine A/B testing expertise, UX research, and statistical rigor to deliver measurable lifts in key metrics like signups, trial-to-paid conversions, and revenue.
CRO consulting rates vary by engagement type. Hourly rates: £150–£250/hour (UK) or $175–$275/hour (US). Project-based: £8k–£25k for strategy and initial experiments, £25k–£70k for comprehensive optimization programs. Retainers: £3k–£10k/month for ongoing experimentation cadence. Pricing depends on scope, complexity, and whether you need full-stack experimentation platform development.
Typical results include 15–35% conversion rate increases for well-executed programs. In my case studies: 18% trial-to-paid lift sustained over three quarters, 35% conversion increase for SaaS onboarding, and 27% faster experiment turnaround. Results depend on your starting point, traffic volume, and commitment to the experimentation process.
Initial discovery and strategy: 2–3 weeks. First experiments: 4–6 weeks (including design, implementation, and statistical significance). Comprehensive programs: 3–6 months for multiple experiment cycles and compounding wins. Most engagements start with a 3-month pilot to establish baseline and prove value.
A/B testing is a methodology for comparing two versions of a page or feature. CRO is the broader discipline that includes A/B testing, but also encompasses UX research, funnel analysis, user interviews, heatmaps, session replays, and strategic prioritization. I use A/B testing as the validation tool within a comprehensive CRO framework.
It depends on the engagement. For strategy and design-only work, you'll need engineering resources to implement experiments. For full-stack implementations, I can build experimentation platforms, feature flag systems, and analytics integrations. Many clients prefer a hybrid: I design experiments and provide implementation guidance, while your team handles deployment.
