The Challenge

Four Obstacles Holding Growth Back

Before partnering with Covenant, American Radiator was facing several key paid advertising challenges that were capping performance and putting profitable growth at risk.

📉

Declining Performance

The account had recently seen a significant drop in results and was barely above break-even.

🗂️

Inefficient Account Structure

Campaigns were split too broadly, making optimization slower and less effective.

🎯

Limited Algorithm Guidance

Google Ads did not have enough clean audience and conversion signals to properly optimize performance.

📈

Need for Stronger ROAS

The main goal was to improve ROI/ROAS while continuing to scale e-commerce sales.
