Stop Flushing Ad Spend: How Bidetlity Scaled Revenue by 55% at an 18% Higher ROAS
Bidetlity is a German direct-to-consumer personal hygiene brand modernizing bathroom routines through sustainable, water-based alternatives to toilet paper. Their product line spans portable travel bidets, ergonomic toilet stools, and mechanical and electric retrofit bidet seats, serving wellness use cases from postpartum care to sensitive skin. Operating on a high-growth D2C e-commerce model, they reached an inflection point where initial traction was strong, but rapid scaling began eroding unit economics and contribution margins.
The Challenge
The core bottleneck holding Bidetlity’s growth back was not consumer demand, but channel efficiency and data visibility across their paid media stack. Paid Search and Paid Social operated in silos with no single source of truth, causing platform metrics to double-count conversions and masking the true marginal return of each ad dollar. On Google, broad Performance Max setups blended high-intent brand searches with low-converting generic queries, while Meta campaigns suffered from creative fatigue and rising acquisition costs that compressed overall margins.
Our Solution
Attribution Foundation via Klar: Integrated Klar multi-touch attribution and marketing mix modeling (MMM) with Shopify store data, moving focus away from in-platform ROAS toward real-time contribution margin and blended efficiency.
Search Architecture & SKU Segmentation: Restructured Google Ads by separating brand from non-brand queries, tightening PMax asset controls, and applying custom label tiers in Shopping feeds to direct ad spend toward high-margin hero products.
Systematic Creative Testing Engine: Built a two-tiered Meta framework pairing a dedicated testing sandbox (targeting specific use cases like postpartum, expat, and travel) with an evergreen scaling engine that only graduated validated, high-efficiency creative.
Funnel & AOV Optimization: Deployed on-site A/B tests across key landing pages and product funnels, introducing strategic bundle tiers, tiered volume discounts, and contextual cross-sells to lift basket size.
Impact at a Glance
+55% Revenue Expansion: Total quarterly revenue surged by 55% year-over-year across the brand's six-figure baseline.
+18% Blended ROAS Lift: Blended ROAS climbed from 3.41 to 4.04 as attribution visibility eliminated wasted spend across underperforming search inventory and social audiences.
+15% Average Order Value (AOV): On-site bundle architectures, quantity breaks, and cross-sells drove consistent basket size expansion before checkout.
-4% Customer Acquisition Cost (CAC): Top-line scale and a +34% lift in order volume were achieved while systematically reducing unit acquisition costs.
