This article highlights F.D.C. Products’ launch of the “ZETA VOICE” review engine for its online jewelry shop, enhancing customer engagement across its portfolio of brands.

F.D.C. Products has introduced the review, word-of-mouth, and Q&A engine “ZETA VOICE” to its official website “4℃ JEWELRY ONLINE SHOP”. The company handles a total of seven brands, including “4℃”, “Canal 4℃”, and “EAUDOUCE 4℃”. Since the birth of the “4℃” brand in 1972, the company has been involved in jewelry planning and manufacturing and currently operates over 100 stores nationwide.
The “4℃ JEWELRY ONLINE SHOP” handles jewelry in various categories such as necklaces, earrings, rings, and bracelets, and also provides services like a “Gift Guide” that allows users to select items based on the recipient or occasion.

Sorting and filtering functions have been implemented for the “Customer Reviews” and “Staff Reviews” sections on product pages. By enabling users to search for reviews based on criteria they want to know, such as “by skeletal type” or “fashion taste”, the company aims to achieve a smooth and comfortable purchasing experience.

The “fit,” an important factor in choosing jewelry, is displayed in a graph on a 5-point scale from “good” to “bad,” making it easy to visually understand review information. Additionally, for staff reviews, the ability to attach images alongside the “fit” graph has been added. By allowing users to check actual wearing images through photos, they can gain a more concrete impression before purchase, leading to increased satisfaction.
Both “Customer Reviews” and “Staff Reviews” have been implemented, allowing reviews to be posted from both purchasers and staff. These reviews can be toggled and displayed within the same screen, enabling users to check posts from both sides with minimal actions. By allowing users to browse reviews from different perspectives without stress, the company aims to deepen product understanding, support product consideration, and enhance purchase motivation.

It is a service that enables the implementation of review content within a website. It allows for the easy introduction of a mechanism to collect user reviews across multiple evaluation axes and display them through various UIs.
