Reducing Customer Acquisition Cost on Google & Meta Ads
How we reduced Taja AI's acquisition cost by 56% on Google & Meta with performance advertising.
The Goal
Taja AI is a two-person startup that built a YouTube SEO tool gaining traction through ProductHunt, AppSumo, and organic search. While sponsored partnerships drove early growth, they were inconsistent and unpredictable. Taja needed a channel for consistent, predictable user growth with a profitable return on ad spend.
The Results
We achieved a 56% reduction in customer acquisition costs and a return on ad spend over 500%. By scaling video campaigns and optimizing retention, Taja AI went from inconsistent sponsorship-driven growth to a predictable, profitable acquisition engine.
Key Actions
Conversion Tracking
Set up end-to-end conversion tracking with custom events tracked server-to-Facebook, giving us clean attribution data to optimize against.
Data-Driven Performance Campaigns
Launched campaigns that started at ~187% return during the learning phase and scaled to 500%+ ROAS through systematic optimization of audiences, creatives, and bidding.
Retention Campaigns
Implemented Churnkey for retention optimization, achieving a 13% decrease in cancellations — directly improving the lifetime value of every acquired customer.
Our Approach
Conversion Tracking
Before running a single ad, we built custom conversion tracking from the ground up. We configured server-side events flowing directly to Meta, ensuring accurate attribution even with iOS privacy changes. This gave us the data foundation needed to make every optimization decision with confidence.
Data-Driven Performance Advertising
We started with broad-targeting video campaigns on Meta to build initial data. During the learning phase, campaigns returned ~187% ROAS. As the pixel learned and we refined audiences, creative, and bidding strategies, we scaled to a consistent 500%+ ROAS. The key was patience during the learning phase and aggressive scaling once we found winning combinations.
Conversion Rate Optimization
We integrated Churnkey to intercept users at the point of cancellation with targeted retention offers. This reduced churn by 13%, which compounded over time — every percentage point of retained users amplified the value of our acquisition spend.
