This presents a chance for marketers to take advantage of the ideal week to reach their communication targets, because the topic will begin to decline after that week and will not return to its peak. With limited time, a marketing initiative must be simple to the demographic being targeted to comprehend and deliver its own distinctiveness to capture the curiosity of their customers.
