Marketing data can help decide when it is time to stop pushing a weak affiliate product. One sign appears when many visitors click the link but very few people complete a purchase. Another sign is when other products on the same site convert better with the same traffic. By comparing clicks, sales, and earnings in reports, marketers can see if effort is being wasted. When numbers stay low for a long period, attention may be better spent on stronger offers. Should data guide this type of decision today?
