Dayparting is a marketing term inherited by search marketing from broadcast and television programming. A day is sectioned off into dayparts, and each daypart carries with it its own audience and, likewise, its own type of content. In TV programming, an early-morning program differs greatly from a prime-time program. Online, dayparting basically means that you have more control over when your ad is displayed. Use dayparting to choose which time of the day or time of the week you’d like to show your ad so that you can target your specific audience with greater efficiency. Often times, advertisers will optimize their ads for when their target audience is most active.
