Even though the content was difficult, it was explained in relatively simple terms.
I was able to immediately apply concepts such as segmentation and presentation of experiment results to my clients’ conversion programs. Ton shared great testing tools for better pre and post test calculations and analysis. I highly recommend this course to anyone who wants to up their A/B testing game!
The A/B testing mastery course was phenomenal! One of the more challenging courses due to Ton’s in-depth teaching on testing math, pre-test planning, testing errors, and quality assurance. It really pushed me – and I loved it.
Here’s why most of your tests are flat (or losing)
With today’s tools, anyone can run A/B tests – but it’s not the tool that determines the outcome of the test. The most powerful tool is still your brain.
The outcomes of your experiments are mostly determined by what you test and the right treatments. Most people who run tests, but are not getting uplifts, are just doing it wrong. They’re either doing spaghetti testing (“maybe this will work!”), building tests based on gut feelings, or are just tinkering with the small stuff (button colors or font sizes) instead of solving problems.
This course is designed to teach you optimal testing strategies, so you can start winning
The “secret sauce” to getting more wins – and bigger wins – is about the process for identifying the biggest opportunities, and coming up with optimal solutions. It’s also about statistics: knowing when you have a false negative on your hands, and when to stop the tests to begin with.
Sometimes it’s the post-test analysis that will give you the insights you need to turn a failing test into a win. You need to know what to look for when you crunch the data.
This course is right for you if…
- You’re responsible (even partially) for the conversion rate of your digital channels.
- You’re part of a team that runs – or should be running – online experiments.
- Your company or client has at least 1,000 conversions coming in per month.
This course is probably not for you if…
- An advanced statistics guru that knows everything about frequentist and Bayesian statistics, including the fact that false negatives are a way bigger problem than false positives.
- Part of an organization with the highest testing maturity level: Evidence-based optimization is in the DNA of how the company operates.
- Working at a company (or for clients) with fewer than 1,000 conversions coming in per month (the first four lessons are still valuable, but the last four won’t apply to your situation).
Skills you should have before taking this course
- Basic digital analytics know-how
- Basic user research knowledge
- Some experience with running online experiments (or you’re going to join a team soon that is doing this)

Pillar 6 – “Bonus”
These bonus lessons are created because of frequently asked questions of students from the A/B-testing mastery course:
- What impact have data tracking issues on my A/B-test?
- What about Multi Arm Bandits, Bandits and AI solutions to experimentation?
- Bayesian or Frequentistic?
- What’s the right A/B-test tool for my company?
