Firebase Analytics日/周/月活跃用户数据技术疑问咨询

Hey there, let's tackle your Firebase Analytics questions with clear, practical explanations!

1. Why DAU × 30 Doesn’t Equal MAU? #

First off, you’re mixing up two core metrics here—DAU counts unique users per single day, while MAU counts unique users across the entire 30-day window (with full deduplication). That’s why your 30K DAU × 30 days = 900K number doesn’t match the 150K MAU from the dashboard.

Let’s break down your example:

• 30K DAU means 30,000 distinct users were active on one specific day. But most of these users will likely return on subsequent days (they’re repeat visitors), so they don’t get counted again in MAU.
• The 150K MAU is the total number of unique users who interacted with your app at least once in the past 30 days. If 30K daily users have high overlap (say, 80% are repeat users from previous days), the total unique users over 30 days only adds up to 150K, not the inflated 900K from simple multiplication.

Your guess about "past 7 days 30K + first 21 days 120K" isn’t accurate either—MAU doesn’t split the window into chunks like that. It’s just a single set of unique users who engaged with your app at any point in the 30-day period, no matter how many days they were active.

2. Questions About Select_Content Event Navigation #

It looks like your question about the path 【Events > Select_Content > A...】 is incomplete. Could you share more details about what you’re trying to do or what’s confusing you? For example:

• Are you struggling to locate the Select_Content event in the Firebase Events dashboard?
• Is the data displayed under this event (like user counts, event frequency) not aligning with your expectations?
• Do you need help filtering, segmenting, or exporting data from this specific event?

Once you fill in those gaps, I can walk you through exactly how to resolve it.
