Online Availability: A Worldwide Study of Extent, Shopper Reactions, and Strategies for Non-Food Categories in Digital Retail

We conducted a research study on Online Availability at pure online and omni-channel retailers in six major countries (China, France, Germany, Japan, United Kingdom, United States), and for six fast-moving consumer goods non-food categories (Baby, Fabric, Laudry, Oral, Shave, Skin).

The goal of the study was to determine the extent that items were availabile to purchase, causes of non-ATP, the incidence of shoppers’ encounters with items not ATP, shopper reactions to these encounters, and sales losses to manufacturers and retailers due to items not being ATP.

Data for the research was obtained through three sources:

– One examined harvested data from retailer web sites in all six countries to determine extent and root causes.
– The second was a shopper survey conducted in the USA examining shopper encounters and reactions when encountering items being not ATP.
– The third was also a shopper survey conducted in the UK, France, Germany, Japan, and China, similar to the USA shopper survey.
The report was published in July, 2018 by the Grocery Manufacturers of Association (GMA).
