May showed which GEOs have truly secured their positions at the top โ the list of leaders remained almost unchanged compared to April. Letโs take a closer look at the benchmarks and analyze the average performance across the top-performing GEOs.
General Trends
Most countries maintained their positions, with the only notable change being Australia replacing France among the strongest GEOs of the month.
Top GEOs: Poland, France, Netherlands, Pakistan, Spain, Czech Republic, Australia, Italy, United Kingdom
As for apps, Chicken, Bonanza, and Zeus continue to dominate, while vertical videos and playables remain the undisputed leaders among creatives. These formats consistently hold usersโ attention and continue delivering the strongest performance throughout the funnel.
๐ต๐ฑ Poland
Metric โ Value
CPI โ $5.17
CPR โ $14.97
CPD โ $93.57
install2reg โ 34.53%
reg2dep โ 16.00%
Poland maintained its position as one of the best-performing GEOs of the month. The most significant improvement came from the deposit conversion rate, which increased from 9.47% to 16.00%. As a result, despite the higher install cost, CPD increased only slightly ($88 โ $94). This is a great example of why looking only at CPI and CPR can be misleading.
๐ช๐ธ Spain
Metric โ Value
CPI โ $7.14
CPR โ $16.10
CPD โ $178.90
install2reg โ 44.32%
reg2dep โ 9.00%
Spain has become more expensive for the third consecutive month โ CPI increased from $6.20 to $7.14, while CPR surpassed the $16 mark. At the same time, reg2dep improved from 7.63% to 9.00%, which kept CPD almost unchanged: $178.31 versus $178.90. The GEO is still performing, but the entry threshold continues to rise. Without precise optimization at every stage of the funnel, margins will continue to shrink.
๐ฆ๐บ Australia
Metric โ Value
CPI โ $7.04
CPR โ $14.32
CPD โ $144.36
install2reg โ 49.20%
reg2dep โ 9.92%
Australia returned to the list of top-performing GEOs and effectively replaced France in the monthly rankings. The relatively expensive installs are offset by strong conversion rates: an install2reg rate of 49.20% and a reg2dep rate close to 10% result in a CPD of $144 โ a solid outcome for a Tier-1 English-speaking market. For teams that have not tested Australia recently, May demonstrated that revisiting this GEO may be worthwhile.
๐ฎ๐น Italy
Metric โ Value
CPI โ $5.34
CPR โ $12.27
CPD โ $135.90
install2reg โ 43.49%
reg2dep โ 9.03%
Italy showed perhaps the most significant improvement of the month. In April, CPD was around $173, while reg2dep stood at 6.37%. In May, deposit conversion increased to 9.03%, reducing CPD by nearly $40. This is one of the clearest examples of how higher-quality traffic directly improves campaign economics.
Conclusion
The market never stands still. As Italy demonstrated, higher install costs can be accompanied by higher-quality audiences. Operating blindly is becoming increasingly expensive: monitoring metrics at every stage of the funnel is no longer optional โ itโs essential.
Thereโs no need to monitor KPIs manually. RentAcc Performance AutoRules track campaigns in real time based on CPD, Spend, CR, and other key metrics, automatically responding to deviations and helping maintain campaign efficiency.
