Shoparize x RevWise
How Agency–CSS Cooperation Unlocks Incremental Google Shopping Performance
Shoparize is a Google Premium CSS Partner delivering incremental revenue for 10,000+ marketplaces, resellers, and brands across the UK and Europe through managed Google Shopping, Microsoft Shopping, and comparison shopping campaigns, on a pay-per-sale basis.
RevWise is the affiliate marketing agency responsible for managing advertiser strategy and partner relationships.
Across multiple advertisers and verticals, this three-party model, where the brand sets commercial terms, RevWise coordinates affiliate strategy and advertiser alignment, and Shoparize invests ad budget and manages Google Shopping campaigns on a pay-per-sale basis, has consistently delivered incremental sales through Google Shopping.
This case study highlights two repeatable best practices from this cooperation that consistently drive results across different brands and categories.

Executive summary
01 Validate
We restructured approval frameworks to align CSS validation with true order quality—unlocking scalable Google Shopping investment, reactivating paused campaigns and driving +233% impressions and +66% YoY GMV without media risk.
02 Activate
By coordinating seasonal CPA uplifts and early best-seller data sharing, we enabled proactive bidding strategies that turned peak demand into +173% YoY GMV and +125% transaction growth across high-competition retail verticals.
03 Scale
Through transparent validation, shared product intelligence and aligned commission structures, we empowered Shoparize to confidently reinvest and expand - delivering incremental Google Shopping revenue at zero ad-spend risk to the retailer.
Fair Validation & Rejection Rates Enable CSS to Scale
Best Practice #1 Fair Validation Enables CSS Scale
Challenge
A leading UK retailer applied a strict validation model that wasn’t aligned with Google CSS traffic, resulting in higher-than-average rejection rates. As CSS partners absorb click costs upfront, excessive rejections limited reinvestment and campaign scale.
Solution
RevWise facilitated collaboration between the brand and Shoparize to refine the validation framework. Rejection rates were aligned to industry standards while maintaining incrementality and order quality. This created a commercially sustainable structure for long-term growth.
Outcome
Previously paused CSS campaigns were reactivated and scaled in Q4, delivering: +233% YoY Google Shopping impressions +66% YoY gross merchandise value +103% YoY transactions
Campaigns became sustainable, driving incremental, high-intent sales without upfront media risk.
Key Takeaway
Transparent, commercially aligned validation frameworks are essential for scalable CSS growth. Fair validation isn’t just operational best practice, it’s a growth lever.
Product & Promotion Sharing Combined with Seasonal CPA Adjustments Improves Efficiency
Best Practice #2 Product Transparency & Seasonal CPA Alignment Drive Peak Efficiency
Challenge
For a leading UK drinks retailer, peak season required early product visibility and commercial flexibility to maximise Google CSS performance.
Solution
RevWise aligned the retailer and Shoparize on a proactive strategy, increasing CPAs for November and December and sharing best-seller data, promotions, and launches ahead of peak.
Impact
+28% YoY conversion rate +173% YoY gross merchandise value +125% YoY transactions
This enabled efficient scaling of high-converting products, increasing impression share and driving incremental growth without media risk.
Key Takeaway
Early product insights and seasonal CPA flexibility allow CSS partners to invest confidently and capture peak demand at scale.
