DS User Focus allows AI to learn from past A/B test results and attribute data to predict target audiences for whom marketing activities such as campaigns and coupons are expected to be effective. Focusing investment on the target audience identified makes possible increased marketing effectiveness and improved ROI. Approaching customer segments that can be expected to use services or purchase products without being targeted for marketing activities, or segments that are not likely to become customers even if marketing measures are implemented, will result in unnecessary costs being incurred and investment efficiency worsened. Furthermore, knowing in advance what segment of customers will only be dissuaded from using services or buying products when targeted with campaigns or coupons will make it possible to avoid unnecessary communication to that demographic and risk disengagement.
