app-store - appannie.com 如何让应用排名达到 1500？

Question

我一直在使用 Apple 的搜索 API 和 RSS 提要来查看收入最高的应用程序。据我所知，Apple 在查看收入最高的应用程序时将结果限制为 300，但不知何故 appannie.com 将应用程序列为收入最高的应用程序为 1500。

有谁知道他们的号码是怎么来的？

Answer 1

App Annie 营销副总裁 Oliver Lo 在接受 pocketgamer.biz 采访时给出了一些提示(引述如下)。

The firm offers a sales analytics tool for developers that both gathers their sales numbers and processes them. Indeed, App Annie's analytics tool is used by over 150,000 apps and, in particular, over 40 percent of the top 100 publishers by revenue.

Once a developer connects their App Annie account with their iTunes Connect account, the sales data is automatically downloaded and processed.

While App Annie keeps the data from that tool completely anonymous, it does combine all the download and revenue data it has access to together to build a global model of sales.

That data is then correlated with the public ranking data in the top app lists to place sales figures with ranks.

Filling in the blanks

"Imagine a Y axis that represents downloads and X axis that represents rankings," adds Lo.

"Essentially we create a model of those two data points, correlating them and growing a distribution of those points through advanced statistics.

"Through that statistical correlation we are able to generate market estimates for the downloads and the revenue of the entire App Store ecosystem."
