🚀 Case Study: Reducing CPL by 68% in B2B Marketing
Background
A B2B provider of crop protection products and seeds aimed to improve lead generation efficiency during a key seasonal sales window. With a solid foundation in digital advertising already in place, the company sought to scale performance while refining lead quality. Primary conversion goals included consultation bookings, newsletter signups, and direct contact requests from prospective clients such as farmers and agronomists.
Objectives
- Reduce the average Cost per Lead (CPL)
- Broaden reach by introducing additional campaign types
- Enhance performance using richer user signals and better targeting
Approach
- Channel Expansion: We broadened the campaign structure by introducing Performance Max and Demand Gen, complementing existing Search and Display campaigns. This allowed us to cover more intent-driven and discovery-based touchpoints across the Google network.
- Audience Refinement: Target groups were revisited and restructured to focus on high-value segments. We prioritized users based on farming profiles, business size, and historic engagement, significantly improving targeting precision and ad relevance.
- Smarter Conversion Tracking: In addition to primary lead actions, we tracked a range of soft conversions—including PDF downloads, key page views, and contact interactions. These were used both as secondary KPIs and to train the algorithm with richer user intent data, helping to drive further efficiency.
- Seasonal Benchmarking: To ensure fair comparison, results were evaluated against the same seasonal timeframe in the previous year (Spring 2025 vs. Spring 2024), accounting for the natural buying cycles in the agricultural sector.
Results
- CPL decreased by €1.78, from €2.62 to €0.84
- The conversion rate rose from 4.21% to 11.94%, a 7.73 percentage point increase – nearly tripling overall efficiency
- Higher-quality signals contributed to improved algorithm performance and more stable campaign delivery during peak demand
