Eureka Achieves 2X Increase in ROI

with Install and Creative Optimizations

The Challenge

Eureka contacted Aarki for a user acquisition campaign to broaden the audience reach of their dating app, Pairs. The campaign’s goal was to win an increased user base with a high engagement and lifetime value and to generate a strong return on investment (ROI). The campaign also aimed to deliver global scale using Aarki’s large repository of data and machine learning capabilities.

The Solution

We kicked off the user acquisition campaign by leveraging Eureka’s first-party data to develop models optimized to increase install volume. We also coupled Eureka’s creative assets and our category expertise to build engaging creatives. 

Install Optimization

In the first phase of our campaign, we aimed for a deep understanding of the app’s users’ behavior to inform our prediction model. On day ten of the campaign, our team launched the Install Optimization phase with the aim to deliver a reasonable cost per install (CPI) and establish volume for further analysis. With this phase, we registered an increase in the install probability and the install rate. Initially, the install rate was above the probability, but it began to trend down at the latter part of the campaign due to model learning.

Creative Optimization

Knowing that the best ads are visually appealing and highly relevant to the users, we began to research our client’s social media accounts, website, databases and App Store pages for new features and updates. In addition, we leveraged Eureka’s own learnings about which photos work best, and also highlighted the unique features of the app to show the user what sets it apart from other dating apps.

When the creatives were ready we ran a multivariate test which allowed us to test various permutations of ad elements, including the background and call-to-action (CTA), to determine the most effective combination for a single ad. The multivariate testing helped us gain valuable creative insight to determine which elements are the most influential.

As we continued testing, our in-house creative team ensured that published ads were always fresh and optimized. We identified the best performing “champion” creative and compared its performance to a “challenger” creative. After identifying the new champion, we increased its media and budget allocation to reach the audience with the highest engagement. Our team repeatedly set new challenges for the champion creative to prevent ad fatigue.
