单页网站的 Google Analytics 跳出率低于 100%
谷歌这样描述它的跳出率指标：
跳出率是指 单页访问或其中的访问 该人从以下位置离开了您的网站 入口（登陆）页面。
我的网站本质上是一个页面，没有出站链接。那么，为什么我的跳出率不是 100%，事实上，大约是 60%！
Google describes it's bounce rate metric thusly:
Bounce rate is the percentage of
single-page visits or visits in which
the person left your site from the
entrance (landing) page.
My site is essentially a single page, with no outbound links. Why, then, is my bounce rate NOT 100%, in fact, it is roughly 60%!!

Google Analytics（分析）将发送到其服务器的点击次数超过 1 次的任何会话视为非跳出访问；它不区分独特和非独特的综合浏览量。
因此，如果有人查看您的单页网站两次（即刷新页面、提交表单等）；任何触发综合浏览量或谷歌分析事件的事件，都会将访问视为非跳出访问。
这表明大约 40% 的访问者与网站的互动超出了单次页面浏览的范围。
（如果您正在进行某种外部链接跟踪，那么点击 Twitter 和 Facebook 链接的人将发送第二次点击，并将被视为非弹跳者；但是，情况似乎并非如此，因此这不是跳出率低于预期的原因）。
Google Analytics considers any session with more than 1 hit sent to its servers as a non-bounce visit; it doesn't distinguish between unique and non-unique pageviews.
Thus, if someone views your 1-page website twice (ie, refreshes the page, submits a form, etc); anything that triggers any pageviews or google analytics events, it will consider the visit a non-bounce visit.
That indicates that roughly 40% of your visitors are interacting with the site beyond a single pageview.
(If you were doing some sort of external link tracking, then people clicking the Twitter and Facebook links would send a second hit and would be treated as non-bouncers; however, this does not appear to be the case, so that is not the cause of the lower-than-expected bounce rate).
当我们将登陆页面更改为与您类似的页面时，我们的跳出率从 45% 上升到 99%，在我们更改了更简单的布局（没有 jQuery 显示/隐藏 div）后，我们设法恢复到 50%。你有 2 个链接 Facebook 和 Twitter。
Our bounce rate went from 45% to 99% when we changed our landing page for one that looks like yours, we managed to get back to 50% after we changed the layout for something more simple, without jQuery show/hide divs. And you have 2 links facebook and twitter.
