根据视频浏览量出价的优化目标是提升视频浏览量。领英如何定义视频浏览量？

LinkedIn defines a video view as when the video plays for two seconds or longer with at least 50% of the video visible on screen, OR when a user clicks on the call-to-action (CTA) button. This comprehensive definition ensures that engagement is captured even if a user quickly interacts with the CTA without a prolonged view. The option stating only "two seconds or longer with 50% visible" is incomplete because it omits the CTA click, which LinkedIn also counts as a view. The option "clicks on the call-to-action button" is too narrow, as it excludes passive viewing.
