Case Study

Maximizing ROI with Performance Max Campaigns

Problem Statement

A mid-sized e-commerce retailer aimed to increase its return on ad spend (ROAS) and reach new customer segments using Google’s Performance Max campaigns. The goal was to consolidate advertising efforts, optimize creative delivery, and achieve better conversions with automation-driven targeting.

Maximizing ROI with Performance Max Campaigns

Challenge

The business faced the following hurdles:

  • Low ROAS from Traditional Campaigns: Existing Search and Display ads weren’t delivering scalable results.

  • Fragmented Audience Targeting: Manual segmentation was limiting reach and relevance.

  • Ad Fatigue: Repetitive creatives led to reduced engagement and high CPC.

Limited Budget Efficiency: Without automation, budget allocation across channels was suboptimal

Solution Provided

We implemented a Performance Max campaign using first-party data for precise targeting, diverse creative assets tailored to customer personas, and goal-based conversion tracking. Google’s automation optimized budget and delivery across channels, while weekly creative testing and performance monitoring ensured continuous improvement.
