To analyze how many times users watch a video within 7 days after sign-up and track this metric's changes over time in Mixpanel, you can use the Retention report. Here's how you can set this up:
1. Go to the Retention report in Mixpanel.
2. Set up your retention behavior:
- First event (A): "Sign Up Completed"
- Return event (B): "Video Watched"
3. Set the retention criteria to "On or Before" with a 7-day interval. This will capture all video watches within 7 days of sign-up.
4. For the measurement, choose "Total Events" instead of the default "Retention Rate". This will show you the count of video watches rather than the percentage of users retained.
5. Set your time range to cover the months you want to analyze.
6. Choose "Month" as your time interval to see the month-over-month changes.
This setup will show you how many times users who signed up in each month watched videos within their first 7 days, allowing you to track changes in this metric over time.
For a more detailed guide on using the Retention report, you can refer to the Mixpanel Docs on Retention.
Remember that you can further refine your analysis by adding filters or breakdowns as needed. For example, you might want to filter for specific user segments or break down by user attributes to gain more insights.
