Efficient Growth: How Bohmeyer & Schuster Increased SEA Revenue by 70%
Operating online via schilder-versand.com, Bohmeyer & Schuster GmbH is an established leader in B2B industrial supply. Faced with complex B2B paid search requirements and stalled digital growth by 2021, they partnered with Muhlert Digital to unlock untapped revenue potential.
The Challenge
When Muhlert Digital audited the client's Google Ads account in 2021, the primary obstacle was a lack of clear account architecture. Campaigns relied heavily on outdated manual bidding strategies and operated in isolation, disconnected from the actual profit margins and economic goals of the business. While Google Ads represented our primary lever, we quickly extended campaign operations into Microsoft Ads to capture high-intent business traffic. Retainer capacity was flexibly allocated beyond basic ad management into targeted mini-projects, including CRO, SEO, data analysis, and advanced tracking, to drive holistic growth.
Our Solution
Margin-Based Performance Clustering: Replaced generic category campaign structures with three profitability-based clusters tied directly to net profit targets and automated portfolio bidding.
Offline Conversion Import: Captured the non-linear B2B buyer journey by linking offline phone, email, and quote orders back to initial ad clicks for full attribution.
Continuous Multi-Year Optimization: Ongoing recalibration across six years to adapt to evolving product lines and major platform algorithm updates.
