Nanigans is an ad engine used by companies such as eBay, Zynga, and T-Mobile to advertise on Facebook. Though this article is based on a single report, this is a report worth paying attention to.

In their report, it was noted that, “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.”

Why the huge difference? iPhone users represent a larger percentage of smartphone web traffic, and spend more money as a group.

Speaking to Businessweek about the mobile industry, Mr. Cook said, “There’s always a large junk part of the market. We’re not in the junk business … There’s a segment of the market that really wants a product that does a lot for them, [emphasis added] and I want to compete like crazy for those customers. I’m not going to lose sleep over that other market, because it’s just not who we are.”

This sounds like arrogance, but it’s really shrewd business. What Mr. Cook is telling us, in other words, is that Apple designs its products for people who aren’t buying bottom of the barrel smartphones. Apple implicitly designs its phones for people who can and do spend money.
