我正在寻找通过在线营销渠道制作的客户旅程用户。我的数据集架构与 Google Merchandise Store 相同，可在此处找到： https ://support.google.com/analytics/answer/3437719?hl=en
这就是我的输入数据的样子（示例）：
+---------------+-------+------------+---------+--------------+-------------+
| fullVisitorId | visit | visitTime | revenue | transactions | channel |
+---------------+-------+------------+---------+--------------+-------------+
| 1234 | 1 | 1516468217 | null | null | Direct |
| 1234 | 2 | 1517937012 | null | null | EMail |
| 1234 | 3 | 1523031014 | null | null | Organic |
| 1234 | 4 | 1530461419 | null | null | Organic |
| 1234 | 5 | 1531152611 | null | null | Paid Search |
| 1234 | 6 | 1531411812 | 1393000 | 1 | Organic |
+---------------+-------+------------+---------+--------------+-------------+
我已经做了这个 SQL 查询：
WITH
_step1 AS (SELECT
DISTINCT
a.fullVisitorId,
a.visitNumber,
a.visitStartTime,
a.Date,
a.totals.totalTransactionRevenue AS totalTransactionRevenue,
a.totals.transactions AS transactions,
a.channelGrouping AS channelGrouping
FROM
`data` a,
unnest(a.hits) as h
)
SELECT
a.fullVisitorId as visitor,
STRING_AGG(channelGrouping, '>') AS CustomerJourney,
SUM(totalTransactionRevenue) AS Umsatz,
SUM(transactions) AS transaktionen
FROM
_step1 as s
GROUP BY fullVisitorId
结果应如下所示：
+--------+----------------------------+---------+---------------+
| visitor| CustomerJourney | Umsatz | transaktionen |
+--------+----------------------------+---------+---------------+
|1234 | Direct>EMail | null | null |
|1234 | Organic | null | null |
|1234 | Organic>Paid Search>Organic| 1393000 | 1 |
+--------+----------------------------+---------+---------------+
我实际得到的：
+--------+-------------------------------------------------+---------+---------------+
| visitor| CustomerJourney | Umsatz | transaktionen |
+--------+-------------------------------------------------+---------+---------------+
|1234 | Direct>EMail>Organic>Organic>Paid Search>Organic|1393000 |1 |
+--------+-------------------------------------------------+---------+---------------+
困难的部分：
有一个转化跟踪期（30 天），这意味着如果自第一次访问以来已过去 30 天或用户完成交易（新行），则将开始新的客户旅程。每次访问都有时间戳。
我必须从哪个查询开始考虑转化跟踪期？
