A/B Test like a Pro!
You can become an A/B testing expert, too. Usually, it takes years. But this A/B testing course will give you a huge head start. You’ll learn the science, the statistics, the business logic, the research framework, the typical mistakes… everything you need to run successful experiments.
90% of online businesses are doing A/B testing wrong!
Here's a typical A/B testing story.
Opening consultation for a data science project. The client proudly mentions:
"We run A/B tests all the time! And we get pretty nice results… Last time we just hit a +60% conversion increase on our main page."
Then we sit down to review those test results. And in 9 out of 10 cases it turns out that the client made a huge mistake somewhere in the process… And the promising conversion boost was only the result of improperly implemented or wrongly evaluated tests. The 60% increases they saw are, in reality, hovering around 0%. (Or worst-case, they turned out to be 20% decreases in conversion.)
Today, everyone can run an A/B test. There are easy to use point-and-click tools. In just an hour you can create and start your first experiment... Sure. But here's the thing: very few online experts can run A/B tests properly.
And as I have written: 90% of online businesses are doing A/B testing wrong! Extremely dangerous… (for them, anyway.)
It's not their fault though. It's hard to get great at A/B testing. It can take years to learn everything:
I created this A/B testing course so you can skip the trial and error phase and get into the race with a head start. You don't have to go through all the typical mistakes to become an A/B testing expert. You can learn from others' successes and failures!
In this course, I'll provide you everything.
Not just everything you need to know about A/B testing... But frameworks, checklists and step-by-step guides that I use myself in my conversion optimization projects.
So when you run your experiments in the future, they will be professionally executed, scientifically correct -- and most importantly, you will deliver real, long-term and outstanding results!
You'll A/B test like a pro!
Data Science + A/B testing
For running proper A/B tests, you don't have to be a data scientist. But you have to understand the scientific background of experiments.
Don't worry, it’s not as complicated as you’d think!
You have to master 3 main domains:
- 1The A/B testing business logic and the strategy. How can you make a real impact with A/B testing? How can you deliver real value (and real profit) for your online business?
- 2The statistical and mathematical background of A/B testing. How can you avoid the typical statistical errors in your experiments (e.g. stopping and evaluating them too early)?
- 3The A/B testing research framework. Instead of testing random gut-feeling ideas (like many do), how can you prioritize your experiments and consistently keep the focus on the most promising, most impactful next steps?
Once you understand these, all you have to do is to learn a few more best practices and watch out for the typical mistakes... And you'll start to see more and more great results in your experiments!
A/B test like a data scientist!
Hi, I'm Tomi Mester, a data professional since 2012. I've seen, managed and run hundreds of A/B tests. Besides, I was lucky enough to get to the industry's most important conferences and learn from the best data analysts.
In the last few years, I’ve collected the best methods (and improved them further in practice); I've seen all the typical mistakes; and I've tested all the best practices on real life projects.
I have a smooth, simple and efficient A/B testing framework -- and a knowledge base that contains everything you need to know. Not to mention the cheat sheets and checklist I use in my own projects.
And you can get access to all these!
A/B testing course... How does it work?
The A/B Test like a Pro! course is an online course. When you enroll, you'll get instant access to the course curriculum, where you will find:
This is a compact yet comprehensive course, by design. In other words, there is everything in it that you'll need and nothing that you won't.
I intend it to be the only A/B testing course you need to take. You take this course, you listen to it, you internalize it -- and then you'll simply know everything that you have to know to run experiments properly and with great results.
Here's the exact curriculum of the course:
MODULE #1 - INTRODUCTION:
MODULE #2 - IMPORTANT INITIAL BUSINESS QUESTIONS:
MODULE #3 - STATISTICAL BACKGROUND:
MODULE #4 - EXECUTION:
MODULE #5 - A FEW SMALLER ADDITIONS:
MODULE #6 - SUMMARY:
You will get evidence-based answers to the most common questions
In the last few years, I’ve gotten a lot of questions on A/B testing. I'll answer all of them in the course. A few (but not all) of these:
This course is based on real life knowledge (and examples of real business cases)
In the last few years, over 1000+ students have enrolled in my data science courses. And I have two golden rules: (1) keep it simple and (2) keep it practical!
So I always put a huge emphasis on explaining everything (even the most complex concepts) in a way that enables everyone to understand it, internalize it and then apply it in real life.
In this A/B testing course, you will see examples from real-life business use cases. Most of the base concepts will be introduced through my (or through my data scientist friends' and colleagues') projects.
Who is this course for?
I guarantee this: This is not another marketing BS course.
Here, we will focus on the practical parts of running experiments - and more importantly how you will be able to use them in real projects.
I recommend this course for people who don't expect A/B testing to be a fancy, one-size-fits-all marketing tool for overnight conversion boost. (Because that'd be a lie anyway.)
It's for online professionals who want to understand the science and the strategy behind A/B testing. Who see that this is a research method. And who are ready to improve their results methodically for real, long-term success.
Do you want to hear a proper "target audience," too? Fine. Here it is.

FAQ: "How deep do we go into A/B testing? Is this interesting for experienced online professionals, too?"
I got this question above from a course participant (before he registered). It might be a relevant question for many, so I’ve just copy-pasted the relevant part of the discussion here:
hi Tomi, quick question: How deep do we go into the topic? Is this interesting for experienced online professionals, too?
hey! Good question -- just in general: we start from scratch, and by the end of the course, we get far enough that everything regarding A/B testing will be completely clear. So I'd say that if someone has been running experiments for years, with great results, it's unnecessary for her to enroll. But for someone who just wants to get started with this field, or has been doing it for, say, half a year - but isn’t sure if she's doing it right, it's 100% that she will profit a lot from the course.
Two more frequently asked questions
As of the current version of the course we don't use any coding languages in it. So you don't have to know any Python, SQL, R or bash.
We focus on understanding the key-concepts: the statistics, the business logic and the processes behind A/B testing. And for that we use the right point-and-click tools.
Yes, I think, everything important is covered in the course. Well, I wanted it to be compact and to-the-point... I personally don't like unnecessary-long learning materials when I learn, so I kept this in mind when I created this course.
Anyway, I keep the right to be wrong about this -- and it's possible that I missed something that should be in the course.
But that's why I added an important extra to the course: a 1-hour 1-on-1 consultation - online - for each participant of this class. There, we can discuss every question that you have after finishing the course. (I've also done this before and I've built in the typical questions/answers already into the current course curriculum... Regardless, I think the 1-on-1 call is a good opportunity to go deeper into the "nitty details" if needed -- also to discuss/brainstorm your specific project, etc...)
