Executive Summary

Looking to improve programmatic advertising performance in driving new signups and streamlining their workflows on the Finnish market, Storytel tapped Ambine for assistance.

Utilizing Ambine to optimize selected line items within their programmatic setup, Storytel achieved the following results:

  • A 56% increase in new signups in line items aimed towards conversions
  • A 54% increase in clicks in line items to aimed at growing site traffic

Client introduction

Storytel is one of the world’s largest subscribed audiobook and e-book streaming services and offers listening and reading more than 500 000 titles globally. 

Storytel operates in over 20 markets around the globe and is headquartered in Stockholm, Sweden.

How we helped Storytel


Storytel’s primary objective was to drive signups to their service and generate additional traffic to include them in more tactical remarketing audiences. Running an extensive programmatic setup, including several line items within Adform’s DSP, the challenge was to determine which line items contributed the most towards their business objectives.

How Ambine helped

By utilizing Ambine’s optimization algorithm to continuously monitor each line item’s performance and reallocate budgets based on their ability to spend their budget and provide the best results, Ambine provided much-needed assistance. Storytel was able to increase the number of new signups and clicks significantly.
Continuous performance analysis and budget reallocation are often time-consuming and laborious.

With Ambine’s help, Storytel effectively streamlined its processes and allocated time towards more strategic initiatives.

Results & future plans

After the initial setup and some amendments to the existing line items, Ambine’s algorithm found improvement opportunities and reallocated budgets to line items with the most suitable conditions, spend the allocated budget, and contribute to the set objectives. As illustrated below, Ambine generated a significant amount of incremental conversions and made continuous adjustments to line items’ budgets to achieve the best possible result.

After the two-month pilot concluded, a 56% increase in signups was reached and a 54% improvement in clicks in line items aimed at driving traffic.

Baseline vs. incremental events delivered by Ambine

Incremental events (conversions) resulting from Ambine’s optimization were directly observable from the data.

Budget changes done by Ambine per line item

Ambine quickly identified best performing line items and reallocated budgets, resulting in more conversions and subsequently decreasing overall cost per acquisition. 

"With Ambine, I both saved time and got better performance out of my line items. I can definitely recommend Ambine if you are running several line items with differing strategies and buying algorithms under a single campaign."
