Google Analytics - GA 在删除 Cookie 后如何跟踪用户?

发布于 2024-12-10 22:35:07 字数 219 浏览 1 评论 0 原文

如果 Google Analytics cookie 从网络浏览器中删除,如果访问的是具有 GA.js 代码的网站的同一台计算机,那么 GA 如何跟踪该 cookie?

例如,www.stackoverflow.com 有 GA.js 代码来跟踪其访问者。用户在他/她的浏览器中打开它,GA 开始跟踪流量,但下一小时所有浏览器 cookie 都会被删除。 现在,GA 将如何跟踪之前访问过该网站的同一用户?

If the Google Analytics cookies are removed from the web browser, how GA tracks that if it was the same computer from where a site having GA.js code was accessed?

for instance, www.stackoverflow.com has GA.js code to track it's visitors. A user opened it in his/her browser and GA starts tracking the traffic, but the next hour all of the browser cookies are removed.
NOW, how GA will track the same user accessed this site before?

*此 cookie 通常会在首次从网络浏览器访问您的网站时写入浏览器。如果浏览器操作员已删除 cookie,并且浏览器随后访问您的网站,则会使用不同的唯一 ID 写入新的 __utma cookie。该 cookie 用于确定您网站的唯一访问者,并随每次页面浏览而更新。此外,此 cookie 还提供了一个唯一的 ID,Google Analytics 使用该 ID 来确保 cookie 的有效性和可访问性,作为额外的安全措施。* - Google:http://code.google.com/apis/analytics/docs/concepts/gaConceptsCookies.html

因此它不会跟踪它们作为同一用户。

如果您非常感兴趣,我推荐他们的“Conversion University”视频:http://www.google.com/support/conversionuniversity/bin/request.py?hl=en&contact_type=indexSplash&rd=1

如果您确实想要,可以交叉引用带有浏览器指纹的 IP 号码,因此可以很好地锁定浏览器/位置组合。然而,有两个原因大多数人不会打扰:

  1. 这是一个很大的痛苦
  2. 它没有给用户提供不被跟踪的选择,他们可能不喜欢这一点,而且它甚至可能不合法,具体取决于隐私随着技术不断变化的法律。

*This cookie is typically written to the browser upon the first visit to your site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to your site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure.* - Google: http://code.google.com/apis/analytics/docs/concepts/gaConceptsCookies.html

So it doesn't track them as the same user.

If you're very interested, I recommend their "Conversion University" videos: http://www.google.com/support/conversionuniversity/bin/request.py?hl=en&contact_type=indexSplash&rd=1

If you really wanted, you could cross reference an ip number with a browser fingerprint, and have a pretty good lock on a browser / location combination as a result. However, there are two reasons most people won't bother:

  1. It's a big pain in the bum
  2. It doesn't give users the option of not being tracked, which they might not like, and it might not even be legal, depending on privacy laws which constantly change with technology.
