我们使用analytics api下载实验和变体,并为我们的访问者进行变体选择(即此处所述的服务器端实验:https://developers.google.com/analytics/solutions/experiments-server-side)
当访问者访问正在进行实验的网址并且他们有选定的变体时,他们会获得如下所述的javascript:
<script>
cxApi.setChosenVariation(1, 'a9BcDEFgHijKl8mON-Opqw');
</script>
这很好用。我们希望运行多个实验(例如,涉及菜单的站点范围实验和特定于页面的实验),变体选择以及我们最终的一切正常。对于用户来说,当他们参与多个实验时,他们会多次调用setChosenVariation:
<script>
cxApi.setChosenVariation(1, 'a1BcDEFgHijKl2mON-3pqr');
cxApi.setChosenVariation(1, 'z9YxWVVuTsrPl8oNM-7lkj');
</script>
我找不到任何理由不应该起作用,但在实验结果中,当发生这种情况时,我们会看到所有用户只被分配到一个实验,尽管两个实验都有结果(创建转换率) > 100%)。
是否有对此行为的解释(我觉得第二次调用可能会覆盖第一次调用?)和/或正确的方法来执行此操作?
非常感谢

轻松回答并不适合我。感谢Google Analytics Debugger扩展,我可以看到ga('send','pageview')
这两个人都在发送有关第二次实验的数据。使用synchronous call工作,我最终得到了类似的东西:
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');
});

我认为您应该在每个实验下设置选定的变体时将实验值发送到Google Analytics。 代码像这样:
cxApi.setChosenVariation(1, 'a1BcDEFgHijKl2mON-3pqr');
ga('send', 'pageview');
cxApi.setChosenVariation(1, 'z9YxWVVuTsrPl8oNM-7lkj');
ga('send', 'pageview');

我意识到这是一个古老的问题,但我最近也不得不想出一个解决这个问题的方法,并且我认为我会分享我的方法,并采用一些现实世界的约束措施。
在高级别,我的方法以下列方式工作:
不幸的是,我不得不采用这种方法作为我正在使用的平台,只允许我编辑全局标题而不是任何类型的页面特定基础。因此,正如我所提到的,它只是针对我正在运行测试的URL检查规范URL标记。
