Question

我已设法通过ISOWeek计算总事件，但不是使用BigQuery计算给定Google Analytics事件的唯一事件。检查GA时，total_events与点上的GA接口匹配，但unique_events已关闭。你知道我怎么能解决这个问题吗？

查询：

SELECT INTEGER(STRFTIME_UTC_USEC(PARSE_UTC_USEC(date),"%V")) iso8601_week_number,
hits.eventInfo.eventCategory,
hits.eventInfo.eventAction,
COUNT(hits.eventInfo.eventCategory) AS total_events,
EXACT_COUNT_DISTINCT(fullVisitorId) AS unique_events
FROM
    TABLE_DATE_RANGE([XXXXXX.ga_sessions_], TIMESTAMP('2017-05-01'), TIMESTAMP('2017-05-07'))
WHERE
  hits.type = 'EVENT' AND hits.eventInfo.eventCategory = 'BIG_Transaction'
GROUP BY
iso8601_week_number, hits.eventInfo.eventCategory, hits.eventInfo.eventAction

Answer 1

Google Analytics中唯一身份的定义是：

具有类别/操作/标签的事件的次数计数在一次会议中至少看过一次。

换句话说，发送特定事件（由类别，操作和标签定义）的会话数。在您的查询中，您计算具有该事件的唯一身份访问者的数量，同时您需要计算会话数量并记住，具有不同标签的事件应计为不同的唯一事件（尽管我们只对类别和行动）。

修复代码的一种可能方法是：

SELECT 
  INTEGER(STRFTIME_UTC_USEC(PARSE_UTC_USEC(date),"%V")) iso8601_week_number,
  hits.eventInfo.eventCategory,
  hits.eventInfo.eventAction,
  COUNT(hits.eventInfo.eventCategory) AS total_events,
  EXACT_COUNT_DISTINCT(CONCAT(fullVisitorId,'-',string(visitId),'-',date,'-',ifnull(hits.eventInfo.eventLabel,'null'))) AS unique_events    
FROM
  TABLE_DATE_RANGE([XXXXXX.ga_sessions_], TIMESTAMP('2017-05-01'), TIMESTAMP('2017-05-07'))
WHERE
  hits.type = 'EVENT' AND hits.eventInfo.eventCategory = 'BIG_Transaction'
GROUP BY
    iso8601_week_number, hits.eventInfo.eventCategory, hits.eventInfo.eventAction

此查询的结果应与GA界面中的数据匹配。

Answer 2

我认为问题在于您只计算已完成指定操作的唯一身份访问者数量，而GA将唯一身份事件定义为“会话包含特定维度的日期范围内的次数”

因此，我只想将您的代码更改为以下内容：

SELECT INTEGER(STRFTIME_UTC_USEC(PARSE_UTC_USEC(date),"%V")) iso8601_week_number,
hits.eventInfo.eventCategory,
hits.eventInfo.eventAction,
COUNT(hits.eventInfo.eventCategory) AS total_events,
EXACT_COUNT_DISTINCT(CONCAT(fullVisitorId, STRING(visitId))) AS unique_events
FROM
    TABLE_DATE_RANGE([XXXXXX.ga_sessions_], TIMESTAMP('2017-05-01'), TIMESTAMP('2017-05-07'))
WHERE
  hits.type = 'EVENT' AND hits.eventInfo.eventCategory = 'BIG_Transaction'
GROUP BY
iso8601_week_number, hits.eventInfo.eventCategory, hits.eventInfo.eventAction

这应该为您提供具有给定事件的不同会话数。

Answer 3

根据您count(distinct )不同内容所需的范围，但您始终需要满足以下条件：

唯一事件是指类别，操作和标签的组合
确保eventAction不是NULL
确保eventLabel不是NULL
eventCategory被允许为NULL

我使用COALESCE()来避免NULL s

示例会话范围

SELECT
  SUM( (SELECT COUNT(h.eventInfo.eventCategory) FROM t.hits h) ) events,
  SUM( (SELECT COUNT(DISTINCT 
    CONCAT( h.eventInfo.eventCategory,
      COALESCE(h.eventinfo.eventaction,''),
      COALESCE(h.eventinfo.eventlabel, ''))
      )
    FROM
      t.hits h ) ) uniqueEvents
FROM
  `google.com:analytics-bigquery.LondonCycleHelmet.ga_sessions_20130910` t

示例命中范围

SELECT
  h.eventInfo.eventCategory,
  COUNT(1) events,
  -- we need to take sessions into account, so we add fullvisitorid and visitstarttime
  COUNT(DISTINCT CONCAT(fullvisitorid, CAST(visitstarttime AS string), 
    COALESCE(h.eventinfo.eventaction,''), 
    COALESCE(h.eventinfo.eventlabel, ''))) uniqueEvents
FROM
  `google.com:analytics-bigquery.LondonCycleHelmet.ga_sessions_20130910` t,
  t.hits h
WHERE
  h.type='EVENT'
GROUP BY
  1
ORDER BY
  2 DESC

HTH！

我们用一些很酷的 CTE 做了一些类似于 @Martin 建议的事情，我们能够 100% 匹配来自 BigQuery 的 Google Analytics 的结果。

查看下面的代码片段，该代码段返回每天的会话总数 + 独特的添加到购物车事件：

   #standardSQL
WITH AN_ATC AS 
(
  SELECT
    -- full date w/ hyphens (ie 2021-01-07)
      CAST(format_date('%Y-%m-%d', parse_date("%Y%m%d", date)) AS DATE) as DATE,
      -- COUNT OF SESSIONS
      COUNT(DISTINCT CONCAT(fullVisitorId, CAST(visitStartTime AS STRING))) AS Sessions,
      -- COUNT OF UNIQUE EVENTS PER SESSION
       COUNT(DISTINCT CONCAT(fullvisitorid, CAST(visitstarttime AS string), 
        COALESCE(hits.eventinfo.eventaction,''), 
        COALESCE(hits.eventinfo.eventlabel, ''))) AS EVENTS
  
  FROM `an-big-query.PROJECT_ID.ga_sessions_*` , 
  UNNEST(hits) as hits
  WHERE
  -- start date
  _table_suffix BETWEEN '20190101'
  -- yesterday
  AND FORMAT_DATE('%Y%m%d',DATE_SUB(CURRENT_DATE(),INTERVAL 1 DAY)) 
  AND hits.eventInfo.eventAction = 'add to cart'
  GROUP BY 
    date
)
SELECT
DATE,
SESSIONS,
EVENTS
FROM AN_ATC
ORDER BY date DESC

哪里，

SESSIONS = Google Analytics ga:Sessions

和

EVENTS = Google Analytics ga:uniqueEvents

两者都带有 eventAction=@添加到购物车
