Unique Reach: Incremental Click Reach

For each time increment within a report — day, week or month — the estimated number of additional new users who clicked on an ad, and who didn't click on an ad during any previous increment. The total for all increments is the click reach for the full reporting period.

For example, if your report is broken down by day, incremental click reach will show how many unique users clicked on Day 1, how many additional users clicked on Day 2, and so on. Users are only counted once and attributed to a particular day. The total for all increments is the click reach for the full reporting period.
