First-click attribution

First-click attribution is a marketing concept that credits the first interaction a customer has with a brand for any subsequent sales. For example, if a person discovers a product through an ad on social media, that ad is considered the most influential touchpoint, even if they later engage with other ads or channels before making a purchase. This approach helps marketers understand which initial interactions drive interest and customer acquisition, guiding them in optimizing their advertising strategies to attract new customers effectively.
