我们使用analytics下载实验和变体,并在我们的终端为我们的访问者做变体选择(即服务器端实验,如下所述:https://developers.google.com/analytics/solutions/experiments-server-side)
当访问者访问正在实验中的url并且有一个选定的变体时,他们会得到如下所述的javascript:
<script>
cxApi.setChosenVariation(1, 'a9BcDEFgHijKl8mON-Opqw');
</script>这很好用。我们希望有多个实验运行(例如,一个涉及菜单的网站范围的实验,和一个特定页面的实验),变体选择和所有的一切都在我们的末端很好地工作。对于用户来说,当他们是多个实验的一部分时,他们会得到setChosenVariation的多个调用,如下所示:
<script>
cxApi.setChosenVariation(1, 'a1BcDEFgHijKl2mON-3pqr');
cxApi.setChosenVariation(1, 'z9YxWVVuTsrPl8oNM-7lkj');
</script>我找不到任何不应该这样做的理由,但是在实验的结果中,当这种情况发生时,我们看到所有的用户只被分配给一个实验,尽管这两个实验都有结果(创建转换率>100%)。

对这种行为有何解释(我觉得第二个电话可能压倒了第一个电话?)和/或一个正确的方法来做这件事?
非常感谢

轻松的回答对我没有用。多亏了Google Analytics Debugger扩展,我可以看到这两个ga('send','pageview')都在发送关于第二个实验的数据。使用synchronous call起了作用,最后我得到了这样的结果:
var sendExperiment = function(tracker, experimentVar, experimentId) {
cxApi.setChosenVariation(experimentVar, experimentId);
tracker.send('event', 'experiment', 'view',{'nonInteraction': 1});
}
ga(function(tracker) {
sendExperiment(tracker, 1, 'a1BcDEFgHijKl2mON-3pqr');
sendExperiment(tracker, 2, 'z9YxWVVuTsrPl8oNM-7lkj');
});发布于 2014-07-23 03:01:43
我认为当你在每个实验下设置一个选择的变体时,你应该把实验值发送到Google。代码如下:
cxApi.setChosenVariation(1, 'a1BcDEFgHijKl2mON-3pqr');
ga('send', 'pageview');
cxApi.setChosenVariation(1, 'z9YxWVVuTsrPl8oNM-7lkj');
ga('send', 'pageview');发布于 2016-06-09 05:41:19
我意识到这是一个老生常谈的问题,但最近我不得不想出一个解决这个问题的办法,我想我会和一些现实世界的约束分享我的方法。
在高层次上,我的方法的工作方式如下:
不幸的是,我不得不将这种方法作为我正在使用的平台,只允许我对全局标题进行编辑,而不是对任何特定页面的基础进行编辑。因此,正如我提到的,它只是检查规范的URL标记和我正在运行测试的URL。
