某個健身服飾品牌即將推出新的高強度健身服裝系列。他們想從報表中瞭解有多少新使用者和不重複使用者購買商品，以及媒體廣告活動觸及了多少這類使用者。 請問他們應該查看哪些報表？

The brand needs to understand new and unique purchasers, which are conversion metrics tracked by Floodlight activities. Floodlight reports provide detailed insights into these conversions, including unique users and new users, based on the Floodlight tags implemented on their site. To see how many users their media campaigns reached, they need a Reach report. Reach reports specifically measure the number of unique users exposed to campaign ads. Standard reports offer general campaign performance data but lack the specific conversion detail of Floodlight reports or the unique user exposure data of Reach reports. Summary reports provide high-level overviews but don't offer the granular detail needed for unique purchasers or reach.
