What is a Minidegree program?

Course is a puzzle piece. Minidegree is the whole puzzle. It’s a complete training program that teaches you everything from A to Z and takes you on a path towards becoming the top 1% marketer.

All of our instructors are hand-picked and carefully vetted. Our approach is straightforward – every instructor needs to be the absolute best in the world at what they do.

Change your results with world-class conversion optimization training

The Conversion Optimization Minidegree by CXL will teach you the methodologies and processes needed to get more wins and bigger wins.

You will develop in-depth knowledge in conversion optimization (driving growth without spending more) and learn processes that you can replicate across any web property.

Access to expert takeaways + guidance can be a game changer when you’re wading through the sea of unreliable and inaccurate information out there.

You shouldn’t be operating without this kind of help.

A program designed to develop true professionals

This in-depth conversion optimization training program will help you become a top conversion optimizer. The skills you gain will benefit you for years to come. You’ll learn how top conversion rate experts in the world approach conversion optimization.

This program will teach you the methodology, tools, and the mindset needed to become a successful optimizer – and make any website sell.

Learn a systematic, repeatable process

True conversion optimization is not about guesswork or running random tests. It’s a process. It’s what separates wannabes from conversion pros. Amateurs think in terms of tactics, while the pros uncover the real issues by following a proven methodology.

After this program, you’ll be able to systematically identify all the places where a website is leaking money, figure out exactly why, create data-backed hypotheses, run tests for learning, and improve your customer theory.

Unique content you won’t find anywhere else

Conversion Optimization Minidegree is the only advanced level CRO training program in the world.

Internet is full of superficial level content on this. More and more junk information is popping up on blogs and places. The best way to learn is from practitioners who’ve been doing this for years and years. We’ve got the best names in the industry to teach you this stuff.

Jeff B.

The curriculum was extremely diverse and comprehensive. It covered all aspects of Conversion Optimization from analytics, to behavior research, psychology, test setup, statistics, etc.

You can dive deep into areas you are not expert in, and bolster other areas you are already strong in.

Winston C.

Once I got into the actual courses, I realized that this was indeed going to be the serious content I was expecting.

Suffice it to say that I’m taking notes.

Steph L.

The most practical and relevant CRO course I have found.
They give you loads of extra materials, guides and templates to work from. Every course is run by a specialist in that field so its relevant to the times.

Will Gray

The Maximizing Audiences for PPC was f*cking excellent!!! I watched the videos many times and recently used some of their tactics and it’s working! CXL ain’t nuttin’ but the truth.

Brandon V.

CXL gave my team the tools to create and run a successful growth team. We were running tests without any thought behind them.

I now have the methodology to be more successful in my day-to-day tasks, and to further my career.


Jonathan R.

CXL showed me how to go from no optimization program to a fully matured program, and how to handle all the nuances that pop up along the way.

Radvilas Š.

Anyone interested in genuinely understanding the math behind CRO and A/B testing absolutely has to use CXL.

My whole team has a great time discussing the material and aligning our views on processes we use, and to come up with ideas to implement in the future.

Bill Angelos

The CRO Minidegree was great.

I previously took the CRO certification from Digital Marketer, and holy crap was I not prepared for how little I knew about CRO before enrolling in CXL’s CRO Minidegree.

I thought I learned a lot, but when I saw what CXL offered vs what they had… it was clear to me that what I thought was a pretty decent course was really something that just covered the tip of what your program touched on.

John O.

This platform truly helped develop my career.

I went from specialist to Head of CRO in 7 months. Many “right timed events”, I agree, but CXL made me confident.

The hours that I spent covering all the lessons were more than enough to avoid imposter syndrome. I was ready when I needed to be.

Josh R.

CXL has lead to more professional growth than any other year of my life. The best educational investment I have ever made.
