The Story

Partners since 2017, Rakuten Advertising and Redbrain have been helping brands across the UK and Europe promote their products and services by tapping into Google Shopping and Microsoft Ads placements.

In early 2023, Redbrain modernised its commission structure by introducing baseline CPA rates per advertiser sector, making it more straightforward for brands to partner with them and adjust rates where needed. The higher the bids Redbrain could win, the higher impression share on product carousels they would win on behalf of their brands, resulting in more clicks and sales. The Rakuten Advertising team worked with the Redbrain Customer Success team to educate brands on this change and negotiate competitive CPA rates. This resulted in Redbrain gaining additional data from Google auctions, allowing them to optimise new and existing campaigns more effectively.

The proactive approach and education of the industry helped Redbrain sustain strong Year-on-Year growth in performance.
