Repro's 'Booster' Improves DECORTÉ Online Boutique's Site Speed Significantly

Repro's 'Booster' Powers DECORTÉ's Online Boutique



Repro Inc., a company dedicated to maximizing revenue through its marketing solutions for web and application platforms, has revealed impressive results after implementing its site speed enhancement tool, 'Repro Booster,' on the official online boutique for DECORTÉ, a brand operated by KOSÉ Cosmetics. This development highlights Repro's commitment to improving user experience in the digital marketplace.

What is Repro Booster?



Repro Booster is a patented site speed improvement tool that enables users to enhance web page loading speeds simply by installing a tag. This innovative solution not only accelerates the speed at which web pages load but also requires minimal operational effort, making it an attractive option for businesses seeking to improve their online presence swiftly and effectively.

While KOSÉ Cosmetics had already been focusing on improving user interface (UI) and user experience (UX) across its six e-commerce sites, there was a perception that these improvements had not sufficiently tackled the issue of site speed. Cosmetic e-commerce sites, in particular, tend to become visually heavy due to the need to communicate product value effectively through images and graphics, which can slow down loading times.

Knowing this, KOSÉ decided to conduct a trial of Repro Booster specifically with the DECORTÉ online boutique, which represents a significant volume of sales and customer views.

Significant Speed Improvements with Repro Booster



Following the implementation of Repro Booster, DECORTÉ’s online boutique experienced notable enhancements in key indicators related to website speed, specifically 'First Contentful Paint' (FCP) and 'Largest Contentful Paint' (LCP). Both of these metrics are critical for assessing site performance and are essential for search engine optimization (SEO).

The results showed:

  • - Mobile Devices:
- FCP improved by 17% (0.76 seconds faster)
- LCP improved by 16% (0.92 seconds faster)

  • - PC:
- FCP improved by 35% (0.55 seconds faster)
- LCP improved by 26% (0.74 seconds faster)

These improvements were achieved while running an A/B test during the trial period, wherein all pages were evaluated without the influence of Repro Booster.

Feedback on Repro Booster’s Impact



Following these enhancements, key representatives from KOSÉ Cosmetics shared their thoughts on the integration of Repro Booster:

Yuu Shiotani, Head of Direct Business Office, said, "As online platforms increasingly serve as the first touchpoint for our brand, enhancing site speed is crucial for providing an excellent customer experience. The DECORTÉ site has demonstrated a notable difference in speed compared to the other five e-commerce sites we manage. Notably, there was a significant uptick in our conversion rate during the trial, indicating that the economic impact was substantial. We achieved our goals for both customer satisfaction and economic effectiveness."

Atsuhiko Sawai, managing systems and adjustments for the e-commerce site at KOSÉ Provision Inc., remarked, "If you are struggling with website speed issues, integrating Repro Booster is a straightforward solution. It’s easy to implement, leads to immediate speed enhancements, and delivers a solid return on investment. The ongoing support, including monthly reports from Repro, has been incredibly beneficial."
