CXL - A/B Testing Mastery course updated

Our A/B Testing Mastery course just leveled up.

Three new lessons. Same mission: teach you to test like an absolute boss.

Most companies run A/B tests. Few do it right.

Too many chase tiny lifts from random button colors or headline tweaks.

Zero impact on revenue. Total waste of time.

This course teaches you how to run tests that move real metrics - revenue, conversions, growth.

You’ll walk away knowing how to:
- Design tests that actually matter - not guesswork or busywork.
- Spot why most tests fail and what to do instead.
- Prioritize tests based on business impact, not gut feeling.
- Analyze results with confidence - no more misreading data.
- Scale winning experiments across the business.

Taught by experimentation legend, Ton Wesseling. The guy top brands turn to when they want results. 20+ years in CRO, keynote speaker, active practitioner.

Updated by Ruben de Boer- another heavyweight in experimentation.

No theory. Just tested, repeatable systems that drive growth.

If you’re tired of running “meh” tests with no real outcomes - this is for you.
Stop testing noise. Start testing for profit.
