Retail Measurement

Nielsen is a global leader in retail measurement services. Our purchasing data offers comprehensive and timely information on market shares, competitive sales volumes and insights into distribution, pricing, merchandising and promotion. By combining this detailed information with and professional consultative services, we offer valuable insights and expertise that help consumer packaged goods (CPG) brands and retailers improve their manufacturing, marketing and sales decisions.


With presence in more than 100 countries, Nielsen collects sales information from more than 900,000 stores within our worldwide retail network—including grocery, drug, convenience, discount and e-commerce retailers—who, through cooperation arrangements, share their sales data with us.

Nielsen collects electronic point of sale (POS) data from stores through checkout scanners. In emerging markets where POS information is unavailable, we use field auditors to collect sales data through in-store inventory and price checks. Nielsen’s stringent quality control systems validate the data before it’s made available in our proprietary software.

Understanding e-commerce sales has become increasingly important for manufacturers and retailers, and e-commerce measurement is a priority for Nielsen. That’s why we offer a global e-commerce measurement solution to help manufacturers and retailers accurately assess their online sales performance and see how online sales contribute to total sales.


Solid sales growth and performance are critical in driving long-term viability and business success for both manufacturers and retailers, and accurate retail measurement is critical in tracking what’s happening in stores and online in an increasingly competitive CPG landscape.


Only Nielsen can provide a comprehensive view on what’s happening with brands in stores across the globe. As part of our commitment to Nielsen Total Consumer measurement, we strive to provide our clients with flexible analytics to understand what is being purchased across all channels—sharing a holistic view of the marketplace. Nielsen’s powerful combination of deep data and insights arms clients with actionable intelligence for their business planning.
