Bad channels and the wrong customers are a major problem for many product launches. Many people sign up but don't use the product, often because they have no need for it or were attracted through ineffective marketing channels. This can be compared to trying to sell wedding dresses to single guys as being futile. To fix this issue, one must filter out bad channels that cost money and eliminate them from data analysis in order to prevent misleading results. This approach allows for more effective use of resources and focuses on converting good traffic rather than stressing about A/B testing or dealing with dead traffic.
