Course overview

Design better experiments with fewer insignificant & throwaway results

10 test design checks to improve the quality of your experiments:


Loosely set triggers dilute your test, extending its duration and causing a loss of power.

✔️ Learn to set better test triggers.


Underpowered tests are likely to lead to insignificant results.

✔️ Learn to estimate and set realistic Minimum Detectable Effects using historical data.


Compromise and confounding often washes out effects.

✔️ Learn to separate and structure tests with minimum confounding.


Lack of iteration and giving up on an a/b test too quickly leads to wasted effort.

✔️ Learn to design your a/b tests in ways that enables you to iterate.


Lack of supporting metrics limits your ability to make correct decisions.

✔️ Learn to include custom metrics in your a/b tests that reinforce your hypothesis.


Lack of segmenting may hide the effect in the general sample.

✔️ Learn to setup your tests with custom segments that may show effects in smaller subsets of users.


Some changes may be too weak for you to see any difference.

✔️ Learn to setup your tests with different intensities.


Some ideas may be better than others.

✔️ Learn to explore and select ideas from historical data to increase your odds of success.


The effect may be too small from a single change.

✔️ Learn to design compound experiments that combine multiple changes with positive probabilities.


Not all experiments need to test for superiority which demands more power.

✔️ Learn to design non-inferiority tests in some situations.

        Jakub's coaching profoundly impacted our A/B testing in the last few years. His blend of creativity, analytical sharpness, and mastery of A/B testing not only deepened our understanding of experiment results but dramatically improved our success and conversion rates. Check out Jakub's course to bring your experimentation to the next level.

        Jakub Linowski has built the best UI pattern repository with over 130 patterns at GoodUI.org. These are tied to over 500 A/B tests to help assess their impact. Because the industry success rate of experiments is only 10-20%, using proven patterns is a great way to raise your success rate and impact.

        Jakub is a veteran in the industry and an innovative thinker with a lot to share from years of meticulously collecting and cataloguing his own experience, as well as that of others. Couple this with a strong understanding of the statistics of A/B testing and it is easy to see how his course will help you avoid common pitfalls in experimentation.

        Jakub has a unique ability to blend rigorous statistical analysis with practical UX insights, hard-earned through years of extensive experimentation. He was an instrumental partner in helping us drive meaningful improvements to our on-site funnel, and I'd recommend the opportunity to learn from him.

        We have been actively using GoodUI to strengthen our test hypothesis for a while already. Jakub has not only built up the most comprehensive catalog of experiment patterns but more over developed one of the best understandings for what works and what doesn’t. Working with Jakub as a coach and designing experiments has been revealing and impactful.

        Collaborating with Jakub has been invaluable for expanding our experimentation roadmap. His insights on data and testing patterns bring clarity and consistently add fresh, impactful ideas to our backlog. Each conversation is engaging and enlightening—I leave every session with new perspectives and actionable takeaways.

Jakub Linowski

Jakub Linowski

Jakub Linowski has been practicing UI Design (since ~2000) & designing experiments (since 2014). He ❤️ inspiring successful replications by growth and experimentation teams.


He also founded GoodUI.org as an active repository of experiments (with winning, flat and losing results) to separate the more generalizable UI, interaction and copy patterns from the more noisy and less predictable ones.


Over the years, Jakub has either been hired, interacted with, shared results, coached and/or learned from over 100 experimentation teams, including: Microsoft, Thomasnet, Booking, Backstage, Yummly, Elevate, Designlab, Reverb, VivaReal, ZAP, Volders, Rollbar, Kenhub, Expert Institute, Drip Agency, FINN, 3Dhub, Metro to name a few.


Jakub is also known to pay close attention to leaders such as: Netflix, Amazon, Airbnb, Bol, Booking, Etsy and Walmart by simply observing what UI changes they A/B test and then writing about some of their publicly visible experiments.


Jakub holds two design degrees, including a MSc in Design for Interaction (Delft, Netherlands).
