通过 Firebase 分析获取不活跃用户的百分比

Question

我正在为我的应用程序进行 Firebase 分析，因此以下问题在同一上下文中 - firebase 是否有 "retained user, who did not open the app but had app on device" 的概念？如果是，它会出现在 Firebase 仪表板上吗？

还有我如何计算每天新安装的用户（新用户）。

感谢所有帮助。

Answer 1

不，无法在 Firebase Analytics 上进行跟踪。当您的用户使用您的应用程序时，Firebase SDK 会向 FA 发送事件，然后他们汇总这些数据以生成报告。

通过这种方式他们可以提取活跃用户，但无法确定安装了该应用但未使用该应用的用户。

您可以根据"first_open"事件确定新用户。此事件显示有多少用户首次打开该应用

将 Firebase 与 BQ 链接后，可以在 BigQuery 中计算 N 天不活跃用户 (Source):

-- N-Day Inactive Users = users in the last M days who have not logged a user_engagement event in the last N days where M > N.

SELECT
  COUNT(DISTINCT M_days.user_id)
FROM (
  SELECT
    user_id
  FROM
    /* PLEASE REPLACE WITH YOUR TABLE NAME */
    `YOUR_TABLE.events_*`
  WHERE
    event_name = 'user_engagement'
    /* Has engaged in last M = 7 days */
    AND event_timestamp > UNIX_MICROS(TIMESTAMP_SUB(CURRENT_TIMESTAMP, INTERVAL 7 DAY))
    /* PLEASE REPLACE WITH YOUR DESIRED DATE RANGE */
    AND _TABLE_SUFFIX BETWEEN '20180521' AND '20240131') AS M_days
/* EXCEPT ALL is not yet implemented in BigQuery. Use LEFT JOIN in the interim.*/
LEFT JOIN (
  SELECT
    user_id
  FROM
    /* PLEASE REPLACE WITH YOUR TABLE NAME */
    `YOUR_TABLE.events_*`
  WHERE
    event_name = 'user_engagement'
    /* Has engaged in last N = 2 days */
    AND event_timestamp > UNIX_MICROS(TIMESTAMP_SUB(CURRENT_TIMESTAMP, INTERVAL 2 DAY))
    /* PLEASE REPLACE WITH YOUR DESIRED DATE RANGE */
    AND _TABLE_SUFFIX BETWEEN '20180521' AND '20240131') AS N_days
ON
  M_days.user_id = N_days.user_id
WHERE
  N_days.user_id IS NULL
