你的客戶是一間美容院，他們即將推出新的影片廣告活動，大多數資訊會從第 25 秒起播送。你想瞭解該訊息獲得的觀看次數。 請問你該在 Campaign Manager 360 報表內查看哪項影片基準？

The correct answer is "Active View: Custom metric viewable impressions" because it allows you to define a specific point in the video (like 25 seconds) as the threshold for a viewable impression. This directly addresses the client's need to understand how many times their key message, which starts at 25 seconds, was viewed. "Active View: Viewable impressions" would count any viewable impression, regardless of how long the video played, which wouldn't isolate the message starting at 25 seconds. "Active View: Conversions" measures post-view actions, not views of the message itself. "Active View: Video completes" only counts when the entire video finishes, which is too restrictive if the key message is earlier.
