Maxime 正在投放一则视频广告，但却发现该广告没有促成转化。根据领英数据，其需要在 90 天内达到多少视频浏览量才能开始建立再营销目标客户？

To build a retargeting audience from video views on LinkedIn, an ad needs to accumulate at least 50,000 video views within a 90-day period. This threshold ensures a sufficiently large and engaged audience for effective retargeting campaigns. Options like 10,000, 30,000, or 75,000 are incorrect as they do not align with LinkedIn's specific data requirements for establishing a video-based retargeting audience. Meeting this 50,000 view minimum allows advertisers to then target users who have already shown interest in their video content, increasing the likelihood of conversion.
