A testing strategy and increase overall AD & creative performance.

The Challenge

Implement a testing strategy to improve AD & creative performance, all in order to scale the Tvornica Snova brand.

Tvornica Snova is a Croatian brand that specializes in making personalized books for families and children.

They came to us with a request to scale their AD & creative performance.

The main goal was to implement a testing strategy and increase overall AD & creative performance. The main metric we wanted to improve were:

  • Click Through Rates (CTR)
  • Cost per Action (CPA)
  • Return on Ad Spend (ROAS)


The Goal – Improve AD performance.

The Solution

The challenge was to improve overall Brand Communication and enhance their communication architecture.

We decided to test with the new Product launch. In order to test and reach new audiences, and create a new revenue stream.

Although the brand is all about emotion, we needed to focus on data. Learn what the customer’s pain points are, and how we solve their problems.

Because we are on a tight schedule and budget we set up a process of a series of Sprints and High Impact Tests. In order to save budget and gain Confidence Intervals with our tests we set up our tests based on Cumulative Binomial Probability Distribution.

Every test reinforces the previous learning and that is how we gained confidence with the test results.


Run a series of High Impact Tests and build up an AD that communicates directly to the User and provides a solution to their problem.


Reconfirming the final test results to improve Confidence in the tests by stress testing the final ADs.
