A/B Experiment Implementation
A/B test execution and UI/UX changes based on prioritized hypotheses. Covers test design, statistical setup, implementation in your testing tool, and analysis with documented winners and learnings.
What's included
- Hypothesis prioritization based on impact, confidence, and effort
- Test design with primary metric, guardrails, and sample size
- UI/UX changes built and QA'd across devices
- Implementation in your testing tool (PostHog, VWO, Optimizely, GA4 experiments)
- Statistical setup with proper traffic allocation and runtime
- Monitoring for sample ratio mismatch and data quality issues
- Results analysis with documented winners, losers, and learnings
- Shipping recommendations and follow-up test ideas
Why it matters
Most CRO programs stall because tests are poorly scoped, underpowered, or never properly analyzed. You get a steady pipeline of decision-grade experiments with a documented record of what works, what doesn't, and what to try next.
What clients say
“Wow! I can't say enough about the team at SmartMetrics! They are super fast, intelligent, and helpful in understanding and addressing your problem. I have worked with them multiple times on different accounts. I highly recommend them! I will continue to use them going forward! Big shout out to Tomas for all his help!”
Anna Crowe
“We worked with Tomas to set up some tracking for marketing analytics on our website. I'd recommend working with him - he's communicative, efficient, and effective.”

“Finding SmartMetrics was a real relief – as a research and education institute with a somewhat unconventional focus within Google Analytics, we previously struggled to find an online training program or consultant that could help us. SmartMetrics helped us to review our entire GA4 setup, and finalized multiple dashboards that addressed our subdomain website complications and redesigned our PDF download tracking. Tomas was clear, communicative and efficient, and took time to provide helpful advice at every stage of the project. We would definitely choose SmartMetrics again for future GA4 improvements.”
