Rakuten Advertising, a digital advertising division of Rakuten Group, was managing a robust campaign structure across various global marketplaces for its client, TASCHEN, a luxury art book publisher. This led to manual management with a need to streamline and automate as much as possible.


Rakuten Advertising partnered with Skai, particularly for our advanced optimization, to become more efficient with Amazon Ads campaign management across TASCHEN’s global presence.

The first step was tapping into Skai’s budget management optimization tools that leverage advanced algorithms and predictive statistical modeling. The team leveraged Portfolio and Budget Navigator across five Amazon marketplaces (US, UK, ES, IT, DE). Rakuten Advertising set up a test of automated optimization rules for TASCHEN’s Amazon Ads campaigns.

All active campaigns were grouped within a Portfolio, a collection of campaigns that share the same goal, set with a minimum target ROI of 10. To best manage budgets, the team also incorporated Budget Navigator, an optimization management set across Portfolios with the same spend goals, with a goal of maintaining the monthly budget pacing to avoid missing sales opportunities. These two optimization rules gave Rakuten Advertising the flexibility to create customized rules with the exact control to hit TASCHEN’s business goals.


Rakuten Advertising streamlined its optimization workflows while improving performance at scale. After setting up Portfolios and Budget Navigator in the U.S. TASCHEN’s performance increased from one month to the next. They saw an ROI increase of 28% and a revenue increase of 24% while lowering ad costs by 3%. So even though the ad spend decreased the next month, they still saw an increase in performance.

“This test was a major success with a 28% increase in ROI, while also not exceeding the given monthly budget. Ultimately it was even more of a success as it proved how useful Skai’s automation tools are and how we can better leverage them to help us manage our campaigns.”
