We [launched] our new company website and I took a lot of what I learned in Karl’s class into consideration when designing the new site.

  3. An in-depth knowledge of how to get useful insights out of the most important (and affordable) user research tools and methods available. Without spending ages staring at boring graphs and numbers.
  4. An incredible amount of tips, tricks and guidelines to convert your visitors into customers. Yes, believe me: it’s incredible. See what I did there?

This course is right for you if…

  • You believe that your site or landing pages can be improved. A lot. But you’re not sure where to start.
  • You have the ambition to grow your online business or those of your clients and you understand Rome wasn’t built in a day. So you’re looking for a strategy and repeatable process to improve any website or landing page step-by-step.
  • You’re a business owner, webmaster, designer, marketeer, … who believes that online marketing shouldn’t be based on gut feeling and opinions. But you’re not sure how to gather those facts.
  • You realize that tools are important but are never the solution as such. You want to learn to get the most out of them. And even more important: how to connect the dots.
  • You understand that usability & conversion optimization are crucial to survive online. But you’re overwhelmed with all the information you can find online. So you’re looking for a hands-on training that’s build around the idea that the proof of the pudding is in the eating.

This course is probably not for you if…

  • You don’t have any ambitions with your website. And you don’t care if you go bankrupt this year.
  • You believe there’s a magic checklist with 10 tips that will make your website the best in the world. That list doesn’t exist. I’ll give you a framework and a hands-on process to make your website better.
  • You believe you can make tons of money online without any effort. Once again: that doesn’t exist. You have to work hard. And improve your site every day. But thanks to the tips & tricks you get during this course you’ll know exactly how to do this and how to get results.
  • You want more visitors on your website. This course is not about attracting more visitors. It’s about getting more revenue and sales from your visitors.
  • You don’t believe in data but gut feeling and opinions. I wish you all the best.

UX and Usability

1 Leave Your Ego at the Door and Find Out What Your Visitors Want

If I’ve learned anything over the past 15 years, it’s that most websites fail due to ego. Companies big and small put themselves first instead of putting their users first. Often without even realising it. Do you talk about what you think customers wan

2 Google Analytics

The sheer volume of data in Google Analytics can feel a bit overwhelming. It’s easy to get lost. Unless you come prepared with the right questions to ask. Your data ain’t going to tell you anything interesting unless you know what to look for. Resource

3 Mouse Heatmaps and User Recordings

Heatmaps are more than just pretty pictures that you can integrate into presentations to impress your stakeholders. They can tell you a lot about your site and your visitors. That is… if you know what you’re looking for. Resources Slides

4 Form Analysis & Getting Ready for Action

On most websites, forms are the last step in converting visitors. Unfortunately, they’re also often the last obstacle. Form analysis tools can give you deep insights into how people interact with your forms. Resources Slides Formisimo

5 UX Tips for Detail Pages & Landing Pages

I’ll show you the ins and outs of every element of a typical page (e.g. header, photo, design, text, call to action, USP, etc.) Not based on gut feeling or opinion, but on real life examples and what we’ve discovered in the previous sessions. Resources

6 UX Tips for Forms

Forms are crucial for every online business. I’ll share all the tips and tricks I know to make sure your visitors will feel the urge to fill out your forms. Okay, maybe that’s a bit exaggerated. But I can guarantee that if you follow my tips, your form

7 Category Pages & Your Homepage

If you sell more than one product or service, you probably have category pages. We will tackle the most common, but often overlooked, problems with these pages. Resources Slides (PDF)

8 Building a Relationship & Summary

When was the last time you went on a website you’d never visited before and immediately bought something? Right. And yet most websites are built around this concept. Someone lands on your website and buys. In this session, I’ll show you some brilliant

Frequently asked questions

What books or resources should I be familiar with?

  • Karl gives similar trainings at digital agencies and they always admit they learned a lot.
  • +5 years experience as a conversion or usability specialist who has hands-on experience based on user research. Not someone who has mainly read many articles about the subject.

What would make a student overqualified for this course?

  • If you have a website and you want to improve it, you qualify.
  • Don’t follow this training if you can only change the content of your website. You’ll learn a lot, but you’ll get frustrated because you can’t change a thing.
  • If you have many years experience as a UX designer, you’ll probably learn more than you would think is possible.

How long should I have been working in UX?

  • Karl recommends reading Don’t Make Me Think to get in the right mindset.

What programs or tools should I  be familiar with?

  • It’s helpful to have experimented with a tool like Hotjar, or another click heatmap, scroll heatmap and user sessions tool. During the training Karl will teach you how to read the data you get from these tools. He won’t teach you how to set them up. So start implementing one of those tools (it’s really easy) and start recording data.
  • Same for form analysis. You can use Hotjar or Formissimo for that. Just start collecting data.
  • These classes are not about the technical use of these tools, it’s how to interpret the data they provide you. So if you start collecting data before this course and if you get familiar with the interface of these tools before, you will get the most out of the trainings.
