“Retailers are realizing significantly greater return from audiences on iOS than audiences on Android,” the report says. “For the first three quarters of 2013, RPC [revenue per click] on iOS averaged 6.1 times higher than Android and ROI [return on investment] on iOS averaged 17.9 times higher than Android.”Another graph showing the return on investment percentages by retailers advertising on Facebook Mobile showed that iOS brings retailers 162% more cash than spent on the ads, while advertising on Android returned 10% less than the cost of the ads:
“Audiences cost more on iPhone, and the reason is that it’s worth it,” Slagen said. “Typically, we’re not looking to acquire one-time customers, we’re looking to invest over time … so we pay more up front for better long-term results.”
The results are interesting given the fact that Facebook has traditionally seen deeper integration within the Android platform, including the release of the Android-only Facebook Home launcher earlier this year, as well as the multiplatform Chat Heads feature which is more feature-filled on Android devices.
