GA 与关于名为 __utmz 的 Cookie 参数

与关于名为 __utmz 的 Cookie 参数

GA Cookie

GA (Google Analytics)

1. 关键词

Google Analytics, Behavioral Targeting, Third party cookie, tracker / ad networks, flash cookie

2. 起因

在做测试时,观察 HTTP 请求的时候,发现一个不太熟悉的 cookie, 因此深入了解了一下。

3. 分析

经过一些搜索,初步推断是 Google Analytics 相关的一些 tracker 投放的 cookie。

GET /s?z=dbname&c=111 HTTP/1.1

举个例子

__utmz=1431777613.utmcsr=(direct)|utmcmd=(direct)



3.1. 部分代码片段

gaforflash (Google Analytics for flash) action script

http://gaforflash.googlecode.com/svn-history/r330/trunk/src/com/google/analytics/campaign/CampaignTracker.as

/**  
 * Format for tracker have the following fields (seperated by "|"):  
 *

<table> * <tr><td>utmcid - lookup table id</td></tr> *

<tr><td>utmcsr - campaign source</td></tr> *

<tr><td>utmgclid - google ad click id</td></tr> *

<tr><td>utmccn - campaign name</td></tr> *

<tr><td>utmcmd - campaign medium</td></tr> *

<tr><td>utmctr - keywords</td></tr> *

<tr><td>utmcct - ad content description</td></tr> *

</table> * should be in this order : utmcid=one|utmcsr=two|utmgclid=three|utmccn=four|utmcmd=five|utmctr=six|utmcct=seven  
 *  
 */

3.2. 更多细节

参考 【GA Basics: The Structure of Cookie Values】

Google Analytics 主要有 5 种 cookie

UTMA – The Visitor Identifier (访客标识符)
UTMB – 30 Minute session identifier (30分钟会话标识符)
UTMC – On Exit session identifier (退出会话标识符)
UTMV – Custom Variable Cookie (自定义变量Cookie)
UTMZ – Visitor segmentation (访客细分)

utmcsr: This is the source of the visitor.
utmgclid: This is the Google ad click ID (thanks to Andy in the comments for bringing this omission to my attention)
utmccn: This is set by the campaign value of the url, or in the case of organic traffic it is (organic).
utmcmd: This is set by the medium defined by the URL.
utmctr: This is the keyword that brought the visitor here in search engine campaigns.
