Users’ events on a product website • viewing the display ads • signing up for promotions or free trials • purchasing products

PARTICIPANTS & DATASET

Three analysts at Adobe • One experienced user • Two novice users

Dataset Size • 6,999 users • 124 events types / 81,563 events

“Event filtering was the most helpful to focus the analysis”

SYSTEM USE

Page 57: Comparing Cohorts of Event SequencesComparing Cohorts of Event Sequences presented by Sana Malik with Fan Du, Catherine Plaisant, and Ben Shneiderman May 26, 2016 — HCIL 33rd Annual

“Reduced metric calculation time provided a much better user experience for data analysis”

SYSTEM USE

Page 58: Comparing Cohorts of Event SequencesComparing Cohorts of Event Sequences presented by Sana Malik with Fan Du, Catherine Plaisant, and Ben Shneiderman May 26, 2016 — HCIL 33rd Annual

Users who had a trial viewed display ads more than the other group & contained more retargeting events. Analysts hypothesized trial users were “explorers” and non-trial users were “experienced users” based on event pattern differences
