Counting how many times an advert on a bus shelter has been viewed is impossible; counting clicks on a blinking banner ad is a doddle. But knowing where each click came from, and how many people are clicking, is harder than it appears.  互联网对于广告人而言太神奇了。没法计算公交站亭上的广告被观看的次数，但却可以轻而易举地计数一条屏幕闪动的广告栏的点击量。可是，要弄清楚每个点击从何而来，有多少人点击过，就比看起来难多了。  Firms dedicated to click-counting put code on websites that reports the times, origins and frequencies of visits, or get consumers to install it buried in browser plug-ins or mobile apps. These record web-users digital calling-cards: the internet-protocol (IP) addresses of the devices they are using. But to assume that each IP address represents a single user in its country of registration is a wild oversimplification.  许多热衷点击量的公司，在网站上附加代码，用来跟踪访问的时间、来源以及频率，或者让用户安装隐藏在浏览器插件中或者是移动应用程序中的这些代码。这些代码记录网络用户的数字名片——这就是用户使用设备的互联网协议地址(IP地址)。但如果想当然假设每个IP地址就代表了在地址注册国的单个用户，那你就弱爆了。  A new report published on November 4th takes a differentapproach.

It puts China and India in the top three for Facebook users.

Conversely, more than three-quarters of respondents in the GWI report said they used more than one device. Another factor is the spread ofvirtua
