Offline Sales Measurement

Also known as offline-to-online purchase measurement, this links online advertising to offline sales by measuring the lift in purchase from those exposed to a digital ad. Vendors such as Nielsen Catalina Solutions, Oracle, IRI, and Kantar Group collect offline purchase data (point-of-sales [POS], coupon, loyalty card, and panel data) and leverage their robust database technology to match consumers who purchased offline with their online cookie.
