RT Journal Article SR Electronic T1 The Marketer's Dilemma: Focusing on a Target or a Demographic? JF Journal of Advertising Research JO J Advert Res FD WARC SP 231 OP 236 DO 10.2501/JAR-53-2-231-236 VO 53 IS 2 A1 Hess, Mike A1 Doe, Pete YR 2013 UL http://www.journalofadvertisingresearch.com/content/53/2/231.abstract AB Data-integration techniques can be useful tools as marketers continue to improve overall efficiency and return on investment. This is true because of the value of the techniques themselves and also because the current advertising market, based on demographic buying, has major opportunities for arbitrage in the range of 10 percent to 25 percent (where in that range depends on the nature of the vertical). The current study reviews different methods of data integration in pursuing such negotiations.
