Proteinum Inc. (Headquarters: Minato-ku, Tokyo, Representative Director: Yohei Yonezawa) has launched an AI-driven data analysis function for its automatic bidding and operation management system for Rakuten RPP ads, "ECPRO," starting April 1, 2026.
This function analyzes past RPP ad data accumulated in ECPRO using AI and proposes CPC (Cost Per Click) adjustment policies and specific improvement actions. It provides an environment where Rakuten store ad operations managers and e-commerce operation outsourcing companies can make data-driven decisions without relying on experience or intuition.
Development Background: Three Challenges in RPP Ad Operations
Rakuten's RPP ads require fine-grained CPC adjustments for each product and keyword, which many responsible personnel may find burdensome.
Don't know how to adjust: Even when trying to adjust CPC, they don't know what approach to take for adjustments.
Lack of time for analysis: Busy with daily order processing and page updates, they have no time to thoroughly review ad data.
Personalization of CPC adjustments: CPC adjustment decisions depend on the experience of the person in charge, making handovers and team operations difficult.
Having managed Rakuten ad operations for over 1,000 stores cumulatively, we have experienced these challenges daily. The ECPRO AI Data Analysis Function was born from the desire to solve these real-world problems.
Overview of the AI Data Analysis Function
AI automatically analyzes past RPP ad data held by ECPRO (click count, CVR, ROAS, CPC trends, etc.) and provides the following:
【Function Overview】
Performance Diagnosis: Analyzes the current status of RPP performance.
Improvement Action Suggestions: Presents concrete CPC adjustment details based on data, along with the rationale.
Verbalization of Adjustment Reasons: AI explains "Why is this adjustment necessary?". It can be directly used for team sharing and client reporting.
【Features】
Achieves "precision specialized for Rakuten RPP ads," which general AI tools lack, due to analysis based on actual operational data accumulated in ECPRO.
Maintains an operational style where "humans make the decisions," not fully automated, because the flow involves confirming analysis results before execution.
Reflects operational know-how cultivated through e-commerce operation outsourcing into the AI's analysis and proposal logic.
Pricing Plans
In addition to ECPRO's basic fee, the AI analysis function is available as an option.
*Data acquisition for 2 years: ¥30,000 (lump sum)
*Up to 20% discount available for annual lump-sum contracts
*ECPRO offers a 2-week free trial.

E-commerce businesses wishing to resolve the personalization of ad operations and build a reproducible operational system within their team.
E-commerce operation outsourcing companies and consultants who want to add data backing to their operational reports for clients.
