Food Beverage And Drugs

Project Overview

"Appier AI technology is capable of identifying all devices owned by the same user from billions of data points. When a potential buyer visits the Carrefour online store on one device (e.g. a PC), Appier can analyze his or her profile and deliver customized product recommendations on other devices owned by the same person (e.g. a phone), motivating the person to buy from the Carrefour online store. Appier’s AI analyzes user behaviors both within and outside of the website to determine the activities of a single user as well as to segment different users. Cross-comparisons with the Appier CrossX database along multiple dimensions allow Appier to locate potential customers in similar segments to expand the original user base".

Reported Results

Carrefour states that:

* Online page views increased 60% month on month
* Increased online store purchases by 25% month on month

Channel Marketing


"Carrefour, a France-headquartered global retailer, is one of the largest hypermarket chains in the world. The brand operates 103 outlets in Taiwan alone. Carrefour launched its online store in Taiwan in December 2015 to address the boom in e-commerce. Over the years, the online market has become increasingly saturated, making it challenging even for big brands to stand out.

Carrefour is expanding online, and wanted to reach more potential consumers through its online store. The marketing team wanted to boost awareness and drive more online purchases, while optimizing the cost per action (CPA)."



Data includes "billions of data points" of users who access the Carrefour online store via various devices
