How Droidhang Tripled Installs with the ironSource ROAS Optimizer

Idle Heroes from Droidhang Games


The Challenge
Idle Heroes’ campaigns were being manually optimized for each source and geo based on ARPU. The hours of manual work meant bids could only be updated once a week. It also limited the reaction time to important supply changes, such as new app launches, holidays, weekends, etc. The campaigns were off goal as bids weren’t high enough on the right sources, meaning Droidhang was losing out on scale and profit.

Droidhang needed a solution that would help them hit their ROAS goal while maximizing volume across multiple traffic sources and geos.

The Solution

ironSource introduced Droidhang to our automated ROAS optimizer solution, which would help them scale their campaigns and bid more granularly with minimum effort.

Wider distribution of bids

Previously, when manually calculating their bids, Droidhang ran nearly 90% of their sources with a single default bid. The ironSource ROAS optimizer provided Droidhang with a wider distribution of bids, increasing bids on high quality sources, and decreasing them on lower quality sources with low ARPU.

This wider distribution helped Droidhang maximize profits and scale where it mattered – generating more traffic from high ARPU sources, and ultimately increasing total ARPU.


The first graph shows the bid distribution across various supply sources. For example, 80% of apps on the manual campaign had the campaign’s default bid in place – in other words, these bids were not being optimized.

The second graph shows the correlation between the bid distribution and the amount of installs.

When looking at both graphs together, we see that only 1% of the sources have bids that are 70% above the default – but they generate 12% of the installs.

Reacting quickly to new supply sources

Looking at a single new supply source, we see how the optimizer adjusts bids early with data it gathers immediately, based both on app category and early performance indicators.

Highlights:

  • Bid adjustments began on the second day following the launch of a new supply source
  • eCPI gradually increased by 370% due to strong performance of the supply source
  • Volume increased by 500% (first week vs last week)
  • Quickly maximized profit from this new supply source

  • “ironSource is a top UA partner of ours. We are very excited about the innovative solutions they are providing for granular and accurate bidding, resulting in great scale and quality. We are confident that with the optimizer and the ironSource team’s dedicated efforts, we will continue to maximize our UA potential and maintain steady growth.”
