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
“Tomas at SmartMetrics has been fantastic to work with. He consistently delivers high-quality work quickly, communicates clearly and proactively, and makes even complex implementations feel straightforward. We’ve partnered with him multiple times now and the experience has been excellent every time.”
Jim Aderhold
Gray Digital Group
“Wow! Blown away by their expertise and speed as well as communication. We had a botched Google tagging job that needed to be fixed and they jumped right in and had it done in the same day. I'm recommending them to everyone I know needing help with the Google suite of business tools.”
Jennifer Roberge
“Working with SmartMetrics has made a huge difference in my business. I now know what is working on an hour by hour basis, and where to invest additional resources. I can’t recommend it highly enough.”
