Lead-Generation
Kostbaar.nl
Project Overview
Kostbaar.nl is a new, high-end player in the Luxury E-commerce and Precious Metals industry (Jewelry, Platinum, Valuation Services). Entering this competitive market demanded a strategy that moved beyond simple sales volume, focusing on brand establishment and high-value conversion efficiency from day one.
The Challenge: Launching a Dual-Funnel Business
Kostbaar.nl faced the dual challenge of operating two distinct, high-value funnels simultaneously:
E-commerce Sales: Driving direct online transactions for products.
Lead Generation (Appointments): Securing high-value, in-person valuation and consultation appointments, which represent the highest potential revenue for the business.
As a new brand, they started with zero market recognition and limited data, requiring an immediate, aggressive, and highly profitable digital footprint to succeed.

Case
Entering the already crowded e-commerce landscape is a significant challenge; successfully launching a new brand and achieving rapid, profitable growth is an entirely different feat. This was the task facing Kostbaar.nl, a new high-value e-commerce brand specializing in luxury items and appraisal services. The brand required a dual-focused strategy: driving immediate online sales while securing crucial, high-ticket, in-person appointments.
This case study details the systematic, data-driven launch strategy that propelled Kostbaar.nl to achieve 500+ Monthly Conversions and 200+ Qualified Appointments in the highly competitive luxury market, establishing a foundation for scalable, high-Return on Ad Spend (ROAS) performance from day one.
Challenges
- Zero Brand Awareness in a Luxury Market:
- Dual-Funnel Complexity (E-commerce vs. Lead-Gen)
- Data Scarcity and Machine Learning Ramp-Up
- High Competitive Barrier to Entry
My Solution
- Value-Based Bidding: We prioritized 'appointment bookings' over general sales, allowing the Google algorithm to identify only high-value customers.
- Google Search Precision: We focused on high-intent, long-tail keywords like "Platinum valuation near me."
- Creative Brand Building: We built brand value using premium imagery through PMax and Discovery campaigns.
- Full-Funnel Setup: We automated the entire customer journey, from awareness to sales.

Impact
The implementation of the structured, data-driven launch strategy ensured that Kostbaar.nl bypassed the typical slow and costly “warm-up” period for new brands, achieving high-volume success quickly. The most direct measure of success was the massive spike in profitable conversions: the brand achieved a steady state of over 500 Monthly Conversions across its entire funnel. Crucially, the strategy succeeded in steering traffic toward the highest-value actions, securing over 200 Monthly Appointments for in-person valuations and consultations, which represent the most significant revenue opportunities for the business. This simultaneous growth in both e-commerce sales and high-ticket leads confirmed the successful execution of the dual-funnel strategy. Furthermore, the campaigns achieved a healthy, sustainable Return on Ad Spend (ROAS) almost immediately, a rare feat for a new brand, validating the efficiency of the conversion value prioritization model. This accelerated success not only established Kostbaar.nl’s immediate profitability but also provided a stable, data-driven blueprint for the brand to confidently scale its advertising investment in the future with reduced risk.

Frequently Asked Questions FAQ
What was the main challenge for Kostbaar.nl in the luxury market?
Kostbaar.nl faced several challenges, including zero brand recognition, a highly competitive market, and the complexity of launching a dual-funnel strategy that simultaneously targeted e-commerce sales and lead generation for high-value appointments.
How did the dual-funnel strategy work?
The strategy was designed to balance two key goals: driving direct e-commerce sales through high-conversion search ads and securing in-person valuation appointments. We used advanced bidding strategies and targeted high-intent queries like “platinum valuation near me,” while also running performance campaigns to build brand awareness.
What tactics were used to overcome the brand awareness challenge?
A multi-channel approach was used right from day one. We deployed a full-funnel structure across Google’s ecosystem, including Google Search, Performance Max (PMax), and Discovery ads. These helped us build brand awareness rapidly while collecting valuable data for audience targeting.We saw a +33% increase in ROAS and a 25% increase in showroom appointments, plus a significant rise in impressions and clicks for previously hidden products.
How did the data-driven approach impact the performance of Kostbaar.nl?
The data-driven strategy allowed us to bypass the typical “warm-up” period, training the bidding algorithms to prioritize high-value actions—appointment bookings—right from the start. This resulted in a strong, immediate return on ad spend (ROAS) and scalable success.
