Case Study: AI BQML Conversion Optimization for Hydratherma

Meet Hydratherma Naturals

Hydratherma Naturals is a clean hair-care brand specializing in curly and transitioning hair. As advertising costs rose and broad audience targeting became less efficient, the brand partnered with us to implement a data-driven, AI-powered conversion optimization strategy using GA4, BigQuery and iBQML.

The Challenge

Hydratherma faced multiple challenges in scaling its digital marketing:

Rising ad costs and declining ROAS: Broad audience targeting was becoming inefficient.
Limited visibility into high-intent visitors: The brand needed to better identify which users were most likely to purchase.
Manual segmentation and slow activation: Audience building and campaign targeting were manual and time-consuming.

The Approch

Our team implemented a data-driven approach using Instant BigQuery ML (iBQML) integrated with Google Analytics 4 (GA4) to uncover deep behavioral insights.

Data Integration & Infrastructure

GA4 → BigQuery pipeline setup

We integrated Google Analytics 4 (GA4) with BigQuery to centralize all event-level user interactions. This enabled complete visibility into customer journeys — from product discovery to checkout — across both web and ad platforms.

Predictive Modeling in iBQML

Building Smart AI Models with iBQML

Using Instant BigQuery ML (iBQML), our team trained predictive models to forecast purchase intent, churn probability, and customer lifetime value (CLV). These models were continuously refined with real performance data for higher accuracy.

Segmentation & Activation

Identifying and Engaging High-Intent Shoppers

We created dynamic audience segments based on behavior, engagement depth, and purchase likelihood. These high-intent user lists were automatically synced to Google Ads and Meta for precise retargeting and personalized ad delivery.

Campaign Optimization & Measurement

Driving Growth Through Continuous Learning

With real-time feedback loops, campaigns were automatically refined for performance — adjusting bids, creatives, and targeting strategies based on AI-driven insights. The team tracked results through interactive Looker Studio dashboards, achieving measurable gains in conversion rate, ROAS, and efficiency.
