How to Evaluate User Quality Across Different Digital Marketing Channels
Contents
Why Is User Quality Assessment Critical?
The core competition in digital marketing has shifted from “acquiring traffic” to “screening high-quality users.” With rising traffic costs and increasingly complex user behavior, blindly pursuing user quantity leads to resource waste: Low-quality users may generate short-term clicks but fail to deliver long-term returns (e.g., fake clicks, coupon abuse). By evaluating user quality, businesses can precisely identify high-value segments, allocate budgets to conversion-ready users, and avoid ineffective spending.
The essence of user quality assessment lies in identifying real value through cohort analysis. Traditional traffic metrics often obscure user heterogeneity - users acquired during the same period may generate vastly different value due to channel sources, motivations, and behavioral patterns.
