Persona.ly worked with Nexon, a South Korean gaming giant owning over 45 gaming titles, including MapleStory, Sudden Attack, and KartRider, to re-engage users of one of their top MMORPG titles – Dungeon&Fighter Mobile.
FTD CVR increase within 3 months
Creative variations tested,
significantly lowering the cost per conversion
When we started running the re-engagement campaigns for Dungeon&Fighter Mobile, our initial approach was to target all churned users that haven’t been active for at least 7 days.
Using Dynamic Audiences we quickly generated a segment of newly churned users to re-engage. The continuous data sharing and Persona.ly’s capabilities to update the Dynamic Audience in real-time, allowed us to keep the audience segment constantly up-to-date by adding freshly churned users and suppressing the targeting of users that re-engaged organically while avoiding manual operations on both Nexon and Persona.ly’s sides.
The initial campaign setup generally targeting churned users already put the campaigns well above the KPI as our targeting algorithms quickly found the best time and placements for re-engaging with users, driving the engagement costs down rapidly and leading to positive ROAS.
Over time, as we gathered enough samples, the target for our algorithms shifted towards increasing the ROAS, which shifted our targeting algorithm to also factor the probability of users making additional purchases, which lead to a significant increase in our payer conversion, as shown in the graphs below.
By slicing and dicing in-app event activity data, our proprietary segmentation engine allows us to identify, define and test performance across various audience segments for re-engagement campaigns. It enables any of our partners to run effective re-engagement campaigns without any additional costs and eliminates the need to use a third-party service.
As soon as the model focusing on ROAS was established and robust, our extensive reach, processing over 1.8M in-app ad auctions per second allowed us to maintain strong performance at a high scale.
Ad-hoc analysis of the targeting algorithm generated specifically for Dungeon&Fighter Mobile informed us that a key feature that increases the likelihood of a user making purchases is the usage of high-end devices (expressed by having more RAM capacity and a higher Pixel-Per-Inch ratio), which aligned well with the context of the title.
Once enough sample data was collected for our ML models to classify the users who are likely to convert by making a first purchase and non-converting users, the payer conversion began to steadily increase as campaigns scaled up.
As can be seen in the graph, over the course of fewer than two months scale increased by 250% while payer conversion doubled.
While re-engaging churned payers is the easier part of the task, the main problem was sifting through the churned users that had not purchased before and re-engaging with those who have a higher probability of turning into paying customers.
Ad-hoc analysis showed that the most important factor increasing the likelihood of a purchase being made was the time passed since the user’s last engagement – how ‘freshly churned’ he was, the shorter the time passed, the higher the conversion rate. As soon as our targeting algorithms realized this relationship, we started to bid more efficiently and our performance improved dramatically.
As can be seen in the graph, the conversion rate for users that churned 7-8 days before re-engaging with them converted almost x5 higher than users that churned 21 days ago or more.
“Despite the time difference, the Persona.ly team offered responsive support and made sure to meet our goals & KPIs, and worked professionally, providing us great results. Our team considers Persona.ly as one of our main DSP retargeting platforms as it outperformed in KR titles in general. We’d love to cooperate further and see how the campaign would perform globally too.”Amy Chung, Global User Acquisition Team at Nexon
