在确定竞拍赢家时，领英会考虑哪些因素？请选择所有合适选项。

LinkedIn's ad auction considers three primary factors to determine the winner: a competitive bid, the Quality Score, and a high Click-Through Rate (CTR). A competitive bid is essential as it directly influences how much you're willing to pay for an ad impression. The Quality Score reflects the relevance and engagement of your ad, which LinkedIn prioritizes to ensure a good user experience. A high CTR indicates that your ad is resonating with the target audience, further contributing to its perceived quality and relevance. Vertical industry is not a direct factor in the ad auction's winner determination; while industry targeting is possible, the auction itself focuses on bid, quality, and engagement.
