A fitness clothing brand is launching a new line of high-impact workout attire. They want to report on how many new and unique users are purchasing their items and are being reached by their media campaigns. Which reports should they be reviewing?

The correct answer is Floodlight report and Reach report. Floodlight reports track conversions, like purchases, and can be configured to show unique purchasers. Reach reports specifically measure the number of unique users exposed to your campaigns, which directly addresses the brand's need to understand how many unique users are being reached. Standard reports provide general campaign performance metrics but don't focus on unique users or conversions in the same specific way. Summary reports offer a high-level overview, lacking the detail needed for unique user and conversion analysis.
