1. The Impact of Rakuten Reviews on Sales

Products with 10+ reviews show 30-50% higher CVR than those without. Review quantity and recency influence both customer decisions and Rakuten search ranking algorithms.

Additionally, in Rakuten's search algorithm (organic search ranking), review count and average rating are important scoring factors. As reviews increase, search rankings improve, leading to more sessions (traffic), which generates further reviews — creating a virtuous cycle of growth.

2. Three Proven Strategies for Increasing Reviews

Simply waiting for reviews naturally, the acquisition rate stays at about 1-3% of purchases. To raise this to 5-10% or higher, we organize the measures in a MECE framework.

Offering Coupons Usable on Next Purchase: This is the most common and effective method. Incentives such as "500 yen off your next purchase for posting a review" also contribute to improving repeat purchase rates.
Optimizing Thank-You Emails: Timed to coincide with product delivery, automated emails request review submissions. It is essential to include a direct link (review submission URL) that makes it easy to post from a smartphone.
Utilizing Package Inserts (Thank-You Cards): Channel the excitement at the moment of unboxing into reviews. Include a QR code and simplify the posting steps to the absolute minimum.

Q. How should you handle negative reviews?

A. Respond promptly, professionally, and publicly. Acknowledge the issue, offer a solution, and use feedback to improve products and service. Never argue with reviewers.
