Persona.ly worked with Nexon, a South Korean gaming giant owning over 50 gaming titles, including Dungeon & Fighter, Sudden Attack, and KartRider, to run a campaign to re-engage users of FC™ Mobile, one of Nexon’s sports games.
Our primary goal with this campaign was to re-engage churned users of the FC™ Mobile game to continue using the app and make purchases. To achieve the ROAS-based KPI, we optimized the campaign towards users who would make a first purchase after re-attribution.

When we started running the re-engagement campaign for FC™ Mobile, our initial approach was to target all churned users who hadn’t been active for at least seven days.
Using our proprietary Dynamic Audiences segmentation tool — available to our clients at no extra cost — we quickly generated audience segments of users who churned within a specific timeframe. Dynamic Audiences integrates directly with clients’ MMP, allowing us to update the audience in real-time to continuously add freshly churned users without delay and suppress segments of users who returned organically.
Within a short time, our algorithm identified which user segments would click the ad and re-engage in the app. This basic targeting model, which focuses on audience segments that have a higher probability of being re-attributed, allowed for gradual campaign scaling while significantly reducing the CPA (cost per first purchase after re-attribution).
As the learning progressed, our algorithm was able to classify users into three groups:
Once we gathered enough data to safely predict which group a given user belonged to based on multiple factors, our algorithm designed a custom targeting model. This allowed for a massive campaign scaling while targeting audience segments and significantly reducing the cost per first purchase after re-attribution.
Within five weeks of starting the campaign, as the learning progressed and we focused on a more engaged audience, we were able to increase the re-attribution volume by 60%.
The FIFA World Cup 2022™ promo campaign allowed for a massive additional scaling by 290% vs. week 1. Despite a decrease in scale straight after the campaign was over, we managed to scale the campaign by an extra 270%, proving the effectiveness and success of our processes. This means we reached an impressive 560% overall campaign scaling.
With the first purchase after re-attribution being a target action and its cost being a KPI, our proprietary algorithm focused on the audience segments who clicked the ad, opened or re-installed the app, and eventually performed the target action.
As the targeting models kept improving, we were able to double the target action conversion rate by the end of month 2.
Due to focusing on the audience based on the IAP (in-app purchases) KPI, our programmatic bidder was able to distinguish and retarget highly engaged users who would make their first purchase after re-attribution and continue making purchases within the app.
During months 2 and 3, the scale was significantly increased due to the FIFA World Cup 2022™ campaign and our bidder adjusted the bidding strategy to acquire users based on predicted value.
Throughout the special promotion, the eCPM increased 5.1x while the cost per revenue event drastically decreased by 83% compared to month 1.
“We find Persona.ly to be a reliable DSP for running re-attribution campaigns. They have an advantage over other DSPs in campaigns where timing is crucial, such as the World Cup, because they can use fast machine learning to optimize the campaigns and reach the user re-attribution cost and UA campaign goals that I have in mind. We look forward to working with them on various campaigns and improving the campaign outcomes by keeping up the communication as we do now.”Dongguk Kim & Yunchul Kim // User Acquisition Managers at Nexon
