Case Study: kGoal x MarketingLeague
Scaling Smart Kegel Trainer to Record-Breaking Sales
Delivering unprecedented growth through strategic multi-channel advertising across Google, Microsoft, Amazon, Meta, and Yandex
Jan 2024 - Present
The Challenge
kGoal is a revolutionary smart Kegel trainer designed to make pelvic floor exercise easier, more effective, and fun. The device blends medical-grade engineering with app-powered guidance, giving users real-time biofeedback, personalized training, and measurable progress tracking.
The company joined us in January 2024 after advertising on Google Ads and Amazon Ads, but didn't manage to scale to a profitable level. kGoal aimed to increase product sales while meeting a target cost per sale for optimal revenue and profitability.
Our Solution
MarketingLeague implemented a comprehensive multi-channel advertising strategy across Google Ads, Microsoft Ads, Amazon Ads, Meta Ads, and Yandex Ads. We developed a full-funnel paid search strategy targeting high-intent audiences, leveraged conversion tracking and granular keyword segmentation, and unified tracking across all ad platforms for accurate attribution.
We improved the conversion tracking system, including tracking and reporting of missed conversions, corrected attribution issues, and used performance insights from one channel to optimize others through data-driven and proprietary optimizations.

Impact & Results
2024 vs 2023 Sales Growth, while keeping the same Cost Per Sale
H1 2025 vs H1 2024 Sales Growth, while decreasing the Cost Per Sale by 5.82%
Sales increased by 190.68% in 2024 vs 2023, with January 2025 sales surpassing the total sales value in all of 2023
Using our proprietary optimization algorithms, we successfully increased their sales and revenue to an all-time high in January 2025.
The company benefited from sales growth within the desired cost per sale, allowing it to increase its ad spend and profit.
All this while reducing sales costs and improving profitability.
We have worked with a number of partners in the past to try to improve our digital advertising performance and never saw the results we were hoping for -- until we started working with Marketing League. Of course, their team has great expertise in crafting and optimizing ad campaigns (both targeting and content/messaging) but in addition, they have a deep understanding of what's under the hood, and their assistance in closing some attribution gaps and better understanding the full chain customer interactions, from initial touch point to conversion, made a huge difference in both revenue volume and efficiency for us. I would definitely recommend them as the best digital advertising partner we have ever worked with.
