What was the challenge?

Despite success in other global markets, Sage Appliance’s European affiliate program was heavily reliant on voucher partners – a tried and tested partner type that tends to dominate the lower funnel. While this delivered volume, it left limited room for innovation, diversification and stronger brand positioning through the affiliate channel.

Sage challenged Silverbean to disrupt this affiliate mix and drive sustainable, high-quality growth across key EU territories. The objectives were clear:

  • Diversify the partner mix with new upper- and mid-funnel opportunities
  • Increase revenue and order volume YoY
  • Scale the program while maintaining a strong ROI
  • Meet and exceed an ambitious revenue target for 2024

The added complexity of launching new strategies in voucher-heavy markets like Germany and France required a bold, performance-led strategy with a long-term approach.

What was our solution?

Silverbean developed and delivered a multi-layered solution, centred around the activation and optimization of Comparison Shopping Services (CSS) partners – a relatively untapped opportunity within Sage’s EU affiliate strategy.

Partner Diversification Through CSS Activation

Silverbean identified CSS as a strategic channel to diversify the program beyond traditional voucher and cashback partners. Two CSS partners were brought into focus:

  • CSS partner 1 – a new addition to the program in 2024
  • CSS partner 2 – previously active but underperforming

Both partners offered strong presence across EU Shopping results, and the potential to drive qualified traffic at scale. CSS partners were selected based on their ability to:

  • Support high-AOV products in competitive search spaces
  • Run flexible CPA-based activity
  • Leverage Google Merchant Promotions for tactical sales pushes

The Silverbean team wasted no time. They began onboarding, negotiating of commercial terms, and overall the integration of both partners into the program – including ensuring tracking readiness and feed compatibility.

Feed Optimization for Shopping Success

The success of any CSS campaign relies heavily on the quality of the product feed. Silverbean first engaged with the priority CSS partners to gauge their feedback on what could be added and what needed amending. The team then worked closely with Sage’s internal teams to audit, restructure, and optimize their Google Shopping feed, ensuring both partners had everything they needed to run effective campaigns.

Key optimizations included:

  • Enriching product data with GTINs, colour, material and localized descriptions
  • Categorizing products to align with Google’s taxonomy
  • Flagging promotional pricing and stock availability in real time
  • Ensuring feed integrity across all relevant EU markets

This groundwork enabled CSS partners to surface Sage’s listings accurately and competitively, improving visibility across Shopping ads.

Tactical Use of Google Merchant Promotions

During a promotional period where Sage Appliances ran a 25% discount campaign, Silverbean advised activating Google Merchant Promotions via CSS partner 1. This allowed promotional messaging to be shown directly on Shopping listings – ensuring Sage stood out against competitors and resellers.

To ensure the success of this optimization, the team:

  • Collaborated with the client to shape compelling promotional messaging that would drive urgency and align with brand tone.
  • Audited the product feed to confirm it met Google’s eligibility criteria for promotions, making adjustments as necessary.
  • Coordinated closely with the CSS partner to implement the promotion across all relevant listings in the Shopping feed.
  • Monitored live campaign performance to assess early traction, adjusting bids and targeting to maximize visibility and return during the promotional window.

This tactic helped to elevate the brand’s presence in Shopping results during a high-intent window, resulting in a substantial uplift in clicks, conversions and revenue.

Data-Driven Commission Optimization

To ensure the channel remained profitable, the Silverbean team tested various CPA levels for each CSS partner – both during and outside of promotional periods. These rates were tiered by product category and adjusted based on:

  • ROI performance by market
  • Average order value (AOV)
  • Revenue vs. action count trends

CSS partner 1, for example, was allocated a temporarily increased CPA during key campaigns to support additional media investment and maximize Shopping real estate.

Ongoing Performance Management & Optimization

The team also worked closely with the CSS partners to:

  • Optimize bidding strategies in real time
  • Monitor impression share, traffic quality, and conversion rates
  • Align CSS tactics with broader affiliate and eComm plans

The team also carried out post-campaign analysis to assess long-term lift in traffic and brand engagement – ensuring each campaign left a lasting impact beyond short-term gains.

What results were achieved?

Sage’s EU affiliate program achieved outstanding growth in 2024, far surpassing expectations. Silverbean’s strategic activation of CSS partners – combined with feed optimization, tactical promotions, and ongoing management – played a pivotal role in delivering these results.
