Single-Touch Attribution is a marketing measurement method that assigns all credit for a conversion to a single touchpoint in the customer journey. This touchpoint could be an ad, email, or social media post that the customer interacted with before making a purchase. It simplifies the analysis by focusing on one interaction, making it easier for marketers to evaluate the effectiveness of specific campaigns. This approach is often used for its simplicity, but it has limitations. By attributing success to only one touchpoint, it may overlook the influence of other interactions that contributed to the customer's decision, leading to a potentially skewed understanding of the overall marketing impact.
