有没有人遇到过这个问题？
我们的移动网站无法使用基于JavaScript的Google Analytics跟踪功能，因此我们必须使用此处的解决方案：http://code.google.com/mobile/analytics/docs/web/#asp
但是，它似乎没有记录过去几天的任何数据。
这是使用的代码：
public class GoogleAnalyticsHelpers
{
public static String GetTrackingImageUrl()
{
StringBuilder url = new StringBuilder();
url.Append("/ga.aspx?");
url.Append("utmac=").Append(Configuration.GoogleAnalyticsKey());
Random randomClass = new Random();
url.Append("&utmn=").Append(randomClass.Next(0x7fffffff));
String referer = "-";
if (HttpContext.Current.Request.UrlReferrer != null && "" != HttpContext.Current.Request.UrlReferrer.ToString())
{
referer = HttpContext.Current.Request.UrlReferrer.ToString();
}
url.Append("&utmr=").Append(HttpUtility.UrlEncode(referer));
if (HttpContext.Current.Request.Url != null)
{
url.Append("&utmp=").Append(HttpUtility.UrlEncode(HttpContext.Current.Request.Url.PathAndQuery));
}
url.Append("&guid=ON");
return url.ToString().Replace("&", "&");
}
}
在ga.aspx页面中：

有没有人遇到过这个问题？我在哪里可以找出为什么没有被跟踪的原因？在过去的几天里，它仅跟踪了2次访问。 FWIW，该网站的Google Analytics状态确实有一个绿色复选标记，似乎工作正常。
感谢您提供任何帮助！
更新：更多信息：
它似乎正在跟踪 1 人。所有视图都在那里（即页面视图正在跟踪）。我想知道是不是因为网络服务器正在提供图像？
答案 0 :(得分：4)
我查看了我们应用的Google Analytics页面设置，然后深入设置，然后进入状态，然后进入高级，然后将单选按钮更改为移动网站。从那里，我们似乎要为移动网站应用使用不同的帐号！也就是说，UA必须与MO交换，而不是典型的基于UA的帐号。那应该解决它！
