Daypart is a marketing strategy where a day is divided into different parts, and advertising or marketing efforts are targeted to specific times of the day. This strategy allows businesses to tailor their marketing efforts to the specific needs and behaviors of their target audience during different parts of the day. By analyzing data on customer behavior and sales patterns, businesses can identify the most profitable dayparts and allocate their resources accordingly. Dayparting can help businesses optimize their advertising budgets and reach their customers more effectively.
