Logins: Track Customer Authentication Events

Logins measures the total number of times visitors authenticated (logged in) to their accounts on your site.

Formula

Logins = COUNT ( Login Events )

Formula Components

Metric	Definition
Login Events	Individual authentication events tracked when a user logs into their account

Metadata
Type	Number
Data Source	Upstack Pixel
Aggregation	Count

Example

Your store recorded 4,823 logins in March, indicating strong account engagement from returning customers.

Week	Logins	Change
Week 1	1,156	—
Week 2	1,203	+4.1%
Week 3	1,187	-1.3%
Week 4	1,277	+7.6%

How It Works

The Upstack pixel fires a login event each time a visitor successfully authenticates on your site. This includes logins from the main site, checkout, and any other authentication touchpoints. Each successful authentication counts as one login event, regardless of session or device.
