[2026 Latest] Even Beginners Can Win! Rakuten Super Sale Strategy: RPP Ads and Negative Keyword Management for Sellers
The Rakuten Super Sale is one of the largest traffic-driving events on Rakuten Ichiba. However, because so many sellers pour their advertising budgets in at once, many beginner shop owners struggle with the issue that "even with RPP (Rakuten Promotion Platform) ads, the return on ad spend (ROAS) doesn't add up." In this article, we will provide a thorough explanation of strategic negative keyword management to beat the competition on a limited budget, along with boosting techniques during the sale period.

1. The Importance of RPP Ads in the Rakuten Super Sale
During the Rakuten Super Sale, the gross merchandise value (GMV) on Rakuten Ichiba jumps to several times its normal level. To ride this wave, appearing on the first page of search results is an absolute requirement. While improving organic search (SEO) rankings takes time, you can secure immediate exposure by utilizing RPP ads.
The following chart illustrates the correlation between traffic and sales via RPP ads during the Super Sale period. By making appropriate bid adjustments, it is possible to concentrate traffic during time slots with high conversion rates (CVR).
2. The Secrets of Setting "Negative Keywords" to Prevent Wasted Spend
While the "Automatic Bidding" feature in RPP ads is convenient, leaving it as-is can cause ads to appear for keywords with low relevance to your products, leading to wasted click charges. Since cost-per-click (CPC) skyrockets during the Super Sale, setting "negative keywords" directly impacts your profit margins.
For example, you should actively add overly broad keywords like "free shipping" or "dirt cheap," model numbers you don't carry, and competitor brand names to your negative list. This allows you to target only users with high purchase intent. This process is essential not only for controlling costs but also for maintaining your ad's "Quality Score."
3. Time-Specific Bid Boosting Strategies During the Sale Period
In the Rakuten Super Sale, there is a clear trend where orders concentrate during the "first 2 hours" and the "last 5 hours." A common mistake for beginners is allocating the budget uniformly across the entire period, resulting in ads stopping on the final day—the biggest sales day—due to a depleted budget.
In the latest 2026 management practices, it is crucial to analyze the "Performance Reports" in RMS (Rakuten Merchant System) in detail to identify the correlation between your shop's search queries and LTV (Lifetime Value). Plan and execute "boost operations" by temporarily raising per-product bid prices to coincide with point-up days like those ending in 5 or 0. This allows you to maximize exposure during time slots with high acquisition efficiency.
FAQ
- Q What is the minimum budget I should start with for RPP ads?
- A. You can set it from as low as 5,000 yen per month, but since competition is fierce during the Super Sale, we recommend starting with a daily budget of around 1,000 yen per product to test and then adjusting based on ROAS.
- Q When is the best time to set negative keywords?
- A. You should complete the settings based on historical data at least three days before the sale starts. Once the sale begins, the golden rule is to check the "Performance Report" in real-time and immediately add keywords that are not leading to conversions to your negative list.
- Q Which should I prioritize: coupon distribution or RPP ads?
- A. Ideally, you should use both in tandem. Use RPP ads to "attract traffic" and coupons to encourage "conversion (purchase)." The flow where a user enters via an ad and decides to buy after seeing a coupon is the most effective way to increase CVR.
