Among the top 10 countries by average iOS CPIs, emerging market Russia and soft-launch favorite Canada displayed the greatest growth, advancing 18% and 14%, respectively.
Google Play Average CPI Shows Growth in Most Countries
Summary
Average CPIs for Google Play experienced robust growth in most countries in September. South Korea, however, felt average CPIs drop 21% month-over-month to $1.15. With South Korea’s average CPI increasing 55% in August, it wasn’t unexpected for the average CPI to taper off in September. The countries that spearheaded Google Play’s average CPI growth included Canada (up 52% to $2.46), Germany (up 33% to $2.33) and the UK (up 30% to $2.02).
Amazon Average CPI Catches Fire
Summary
Average CPIs for Amazon were on fire in September (pun intended). The top 10 countries by average CPIs for Amazon were all up month-over-month. In particular, average CPIs swelled by 19% in the US, 14% in the UK and 37% in Mexico.
With Apple potentially recording 20 million iPhone 6 sales, we expected advertisers to bid slightly more for installs on iPhones. While we saw iPhone bids increase in September, it looks like bids rose for every platform, showing that seasonality had a stronger effect on average CPIs in our Network than the iPhone 6 release.
