Enoteca Co., Ltd. Solves Speed Issues Unresolved by AWS Migration with Speed Kit, Achieving 40% Improvement in LCP

Gaprise Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Ryoji Kai, hereinafter "Gaprise") announces that it has supported Enoteca Co., Ltd. (hereinafter "Enoteca") in the full implementation of its website acceleration tool "Speed Kit" on Enoteca's wine e-commerce site, achieving a 40% faster page loading speed (LCP: Largest Contentful Paint) across the site and an 8.0% increase in CVR (conversion rate). This case successfully addressed the challenge of improving site speed while maintaining rich content, without modifying the existing system.

Background and Challenges

In the e-commerce industry, rising customer acquisition costs have heightened the importance of not losing customers who have already visited a site. Among various factors, page loading speed has become one of the most critical metrics directly affecting the purchasing experience.

For Enoteca, rich content conveying stories about wine origins, producers, and ways to enjoy wine has been a key competitive advantage. However, this richness in content also became a structural cause of slow page loading. Increasing loads from external tools, images, and scripts accumulated over time, and even after migrating servers to AWS, fundamental speed improvements were not achieved. Despite a strong desire to make the site faster, the complexity of the existing system made it difficult to identify a viable solution.

Rationale for Adopting Speed Kit

Speed Kit, provided by Gaprise, is a website acceleration tool that works simply by adding one line of JavaScript code to the HTML. Since processing occurs via the browser's service worker (a mechanism for cache management running in the background), it can be implemented without modifying any system configuration, including fully in-house developed (scratch-built) e-commerce systems.

Before full implementation, Enoteca conducted a small-scale proof-of-concept (PoC) test and confirmed measurable speed improvements. Furthermore, internal team members who use the site daily experienced the post-implementation site firsthand and subjectively felt that it was "clearly faster," which helped drive the decision for full adoption. The combination of objective data verification and qualitative feedback from on-site employees led to the final decision.

Results After Implementation

Page loading speed (LCP): 40% faster across the entire domain (after improvement: 1.524 seconds)

Session duration: Increased by 8.6%

Add-to-cart rate: Increased by 10.2%

CVR (conversion rate): Increased by 8.0%

Further details are available as an interview article on Gaprise Media MarTechLab.

Significance of the Results

Improved loading speed reduces user drop-off by displaying pages faster, leading to longer viewing times and a chain of behavioral changes such as increased add-to-cart actions and purchases. These results empirically validate the causal chain: speed improvement → longer session duration → more add-to-cart actions → higher CVR → improved revenue.

As competition for customer acquisition intensifies and advertising costs rise, enhancing site quality as a reliable "receptacle" to retain returning visitors represents one of the shortest paths to improving e-commerce profitability. The Enoteca case demonstrates that it is possible to achieve speed improvements without compromising content quality.
