New Udemy courses

To help people who don’t have the budgets to pay for the CRO business-to-business courses, new courses will be released in 2020. Do you want to know when a new course launches? Stay up to date by connecting with me on LinkedIn.

A book on psychology & CRO

If you are interested in the psychology behind conversion optimization, soon you´ll find a book here explaining just that. It will cover research in psychology in a fun and engaging way, with practical examples you can implement straight away in your conversion optimization practices.

Charity help blog

With knowledge on influencing human behavior, one should also use it for the greater good. I will help charity organizations improve their website, build a behavioral report for other charity organizations and report on it in my blog. Are you a charity organization with at least 10,000 website users a month? Feel free to contact me.

Who am I and why Conversion Ideas?

My name is Ruben de Boer. As a CRO Manager and consultant at Online Dialogue, I have the pleasure to work with great people on great websites every day. With Conversion Ideas my goal is to help people who don’t have the money, or budgets from their employer, to access expensive business-to-business courses. As well as (e-)meet amazing like-minded people.

  • Through high quality, practical and engaging online courses, I want to help people enjoy, start with and excel in Conversion Optimization.
  • The book on Online Psychology and CRO is for people who love to read and are interested in the topic of psychology. (The book will be available in 2020).
  • In 2020, I will help charity organizations and write a blog about it. Because I belief if you have the knowledge and passion for something, you should also use it for the wellbeing of others.
