google-analytics - Google Analytics 和 Piwik 差异

Question

大家好，我想知道是否有人和我遇到同样的问题。我有 2 个跟踪器，分别是 Google Analytics 和 Piwik，但一段时间后我发现存在差异。请阅读以下内容了解更多信息。

这是昨天的数据(当时是 New Piwik Last Week v1.7.1 版本)。 GGA:14 803 次访问(独立访客) Piwik:10 254 次访问(独立访客)

31% discrepancy.

问题 我需要做什么才能匹配记录？或者哪个统计数据是正确的？

如有任何建议，我们将不胜感激。

Answer 1

对于不同的程序，它们都是正确的。差异在于他们如何计算唯一访客。没有两个统计聚合器的工作方式相同。

谷歌分析What's the difference between the 'Absolute Unique Visitor' report and the 'New vs. Returning' report? :

Absolute Unique Visitors

In this report, the question asked is: 'has this visitor visited the website prior to the active (selected) date range?' The answer is a simple yes or no. If the answer is 'yes,' the visitor is categorized under 'Prior Visitors' in our calculations; if it is no, the visitor is categorized under 'First Time Visitors.' Therefore, in your report, visitors who have returned are still only counted once.

Piwik FAQs :

How is a 'unique visitor' counted in Piwik?

Unique Visitors is the number of visitors coming to your website; Unique Visitors are determined using first party cookies. If the visitor doesn't accept cookie (disabled, blocked or deleted cookies), a simple heuristic is used to try to match the visitor to a previous visitor with the same features (IP, resolution, browser, plugins, OS, ...). Note that by default, Unique Visitors are available for days, weeks and months periods, but Unique Visitors is not processed for the "Year" period for performance reasons. See how to enable Unique Visitors for all date ranges.

它们都使用 cookie 来确定唯一性，但都以不同的方式计算它们。并排比较统计数据包时，这是苹果和橘子。

检查除唯一访客之外的其余统计数据。如果全面存在较大差距，请仔细查看两者的实现情况。

如果两种实现方式均顺利，则选择其中一种并使用它进行统计。总体趋势就是您要寻找的内容。您想要上升的统计数据上升了吗？您想要下降的统计数据会下降吗？
