The Challenge
Suzana was looking for a way to effectively expand its performance marketing beyond traditional channels — without a significant increase in costs. Although the client initially had some concerns about CSS advertising, open communication and expert guidance from Expandeo helped overcome these doubts. As a result, Suzana confidently embraced the strategy and, through our smart multi-channel setup, gained a high-performing and flexible new marketing channel.
Our Strategy
- Implemented Google CSS Shopping Ads as the primary channel
- Expanded visibility by launching campaigns in Bing CSS and our own price comparison platform
- After initial testing and performance review, optimized the product feed and shifted strategy in March to promote top-converting SKUs using more aggressive bidding
Channel breakdown (Feb–Apr 2025):
- Google CSS: 61% of total revenue
- Bing CSS: 34%
- Comparison engine: 5%
