This is the third part in a series on The Basics of Online Advertising. I’ll be posting a new entry each week for the next four or five weeks – or maybe I’ll just keep goin’!
What is day parting?
Day parting a campaign restricts the campaign to serving only during certain times of the day. Day parting typically takes the form of a serving window between particular hours; a setting may have a starting hour and a stopping hour. The campaign serves normally between the hours, but doesn’t serve at all outside of them. Day parting is not the same as a start and stop time for a campaign. When a campaign is day-parted it will serve during the “on” hours every day the campaign is scheduled to run.
In a typical RTB transaction there’s a user ID, pulled from the user’s cookie or some form of server side system, which is passed to the DSP from the SSP. That ID is, in most cases, the DSPs record locator for the user’s information. Most DSPs have a server side data store where this information is housed, updated and augmented from a variety of sources including data companies like Blue Kai and Excelate and their ilk. DSPs may also be collecting and distilling information based on bid request activity from that user (although most SSPs put language into the contracts governing the use of this “bid stream” data) or retargeting data gathered for their customers. This type of data system is generally referred to as a Data Management Platform (DMP) in the industry. While there are some stand-alone DMPs out there, more and more DSPs are integrating or building their own.
