如何查明弹跳率

本帖最后由 luck 于 2015-1-19 20:40 编辑


常听说这个词，我也想看看自己网站的弹跳率，如何查明。是这个单词bounce rates
谢谢

简单一点的办法，加统计工具。

var et = (86400 - ed.getHours() * 3600 - ed.getMinutes() * 60 - ed.getSeconds());
ed.setTime(now + 1000 * (et - ed.getTimezoneOffset() * 60));
document.cookie = "cnzz_a1562522=" + cnzz_a + ";expires=" + ed.toGMTString() + "; path=/";
document.cookie = "vw1562522=" + escape(vw) + ";expires=" + ed.toGMTString() + ";path=/";
document.cookie = "sin1562522=" + escape(sin) + ";expires=" + ed.toGMTString() + ";path=/";
ed.setTime(now + 1000 * 86400 * 182);
document.cookie = "rtime=" + rt + ";expires=" + ed.toGMTString() + ";path=/";
document.cookie = "ltime=" + now + ";expires=" + ed.toGMTString() + ";path=/";
document.cookie = "cnzz_eid=" + escape(eid) + ";expires=" + ed.toGMTString() + ";path=/";一种方法是写入cookies，当页面跳出的时候，记录时间。如上面cnzz的统计就是用这样的代码，还有一种就是利用js里面的onload和onunload函数，然后ajax入库。
