On this day, we answer several questions about your previous and future optimization efforts. The list of questions depends on your individual state of conversion optimization. Maybe you are just starting out, maybe you already have a lot of optimization history.


An initial set of CRO tools

To ensure an optimal foundation for all future conversion efforts, I will equip you with a set of to-dos and tools.

The set is based on your individual CRO status quo, and can include tools like:

A list of event and goal trackings for your web analytics
with the goal to do better, more exact, and more valid conversion research for more conversion optimization success.

A catalog of requirements for a CRO analytics dashboard
with the goal to monitor crucial CRO metrics, and to save time in conversion research.

A unique, step-by-step conversion optimization process for your business
with the goal to assure long-term CRO success, involve stakeholders, handle approvals, and ensure testing quality.

A data sheet for experiment ideas (on steroids)
with the goal to avoid gut-feeling-based testing (it’s bad), to prioritize the most promising ideas, and to discuss test variation setups.

A catalog of requirements for CRO documentation
with the goal to document tests and learnings, make them searchable and usable for future tests, file best-performers, and report to stakeholders.

But wait!Who is talking here?

My name is Nils Kattau. But call me Nils.

I am one of the leading conversion optimization experts. Since 2004, I ran 2,000+ A/B/n-tests for more than 300 companies and built one of the biggest agencies specialized in conversion optimization.

Since leaving my agency in 2016, I’ve been focusing on my own clients and projects.

I am co-author of several books about conversion optimization, online marketing, and growth hacking. Each year, I speak on the stages of many popular conferences and well-known companies. Also, I am the CRO university lecturer for Google’s first European Digital Marketing Degree.

I work with small and medium sized brands as well as market leaders like Facebook, Airbnb, PayPal, Amazon Audible and ebay with the goal to improve my clients’ conversions or knowledge in the field.
