We’ve updated user activity to separately track when a person first visited and when they became identified.

Problem Statement

Previously, First seen actually meant “first identified,” and Last seen was the most recent visit, leaving a gap in understanding the true first touch and acquisition source.

For example: If someone arrived anonymously via a paid ad on Jan 1 and only signed up (became identified) on Jan 5 via organic, the old model set First seen = Jan 5. You lost the original acquisition context (the paid ad on Jan 1) and misattributed that user’s source.

Solution

We added Identified on to sit alongside First seen and Last seen. Now you can see:

First seen: The user’s first visit (often anonymous). Ideal for true first-touch attribution; UTMs, referrer, campaign, device, etc.
Identified on: The moment the user was first recognized (e.g., signup, login, email/phone captured). Ideal for lifecycle analytics—conversion timing, identity resolution, and post-ID engagement.
Last seen: The user’s most recent visit or activity, as before.

Where to find it

Go to the segments section and here in User One View tab, open a user profile. You’ll now see First seen, Identified on, and Last seen with their respective timestamps.

Updated User Acquisition Activity: First seen and Identified on

In the acquisition tab, you’ll also see user acquisition properties based on true first-touch attribution, rather than the acquisition source when the user was identified.

This change restores accurate first-touch attribution, clarifies conversion timing, and keeps your ongoing engagement tracking intact.
