【May 19 (Tue) Online】Just Before Rakuten Super SALE! Self-Service RPP Optimization. How to Effectively Utilize a Monthly Budget of 20,000-30,000 Yen to Simultaneously Achieve "ROAS Improvement and Sales Growth"? 【Online Seminar Held】

Nihon EC Service Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Keisuke Yabunaka), which operates the "EC Masters Club" with over 2,600 Rakuten shops nationwide, will hold an online seminar titled "Just Before Rakuten Super SALE! Self-Service RPP Optimization. How to Effectively Utilize a Monthly Budget of 20,000-30,000 Yen to Simultaneously Achieve 'ROAS Improvement and Sales Growth'?" on May 19, 2026 (Tuesday).

This seminar is aimed at e-commerce businesses on Rakuten Ichiba who feel challenged by the cost-effectiveness of RPP. We aim to provide practical know-how that will enable e-commerce businesses to reduce wasted advertising costs and set up RPP like a professional.

Background of the Event

It is not uncommon for RPP on Rakuten Ichiba to be operated "as set." Many e-commerce businesses find themselves busy with product registration, shipping, and customer service, only to realize that advertising costs are being consumed without leading to sales. Against this background, Nihon EC Service Co., Ltd. planned this seminar to convey an "automation mechanism" that automatically cuts wasted advertising costs and makes it easier to increase sales and ROAS, so that e-commerce businesses can operate RPP like a professional in a short time, even when busy. Through the know-how of the EC Masters Club, we aim to help e-commerce businesses reduce waste in advertising operations and achieve EC management that maximizes profits.
