Madison Brook International was facing high customer acquisition costs (CAC) and inconsistent lead generation through its PPC campaigns. Their goal was to increase visibility, generate quality leads, and reduce CAC.
Solution
We focused heavily on Quality Score, decreasing CPC and improving Ad Rank, which reduced lost impression share (more traffic, less cost). We refined keywords & bids, optimised ads, and adjusted audience targeting for better-quality conversions, with continuous A/B testing for ongoing improvements.
Result
Our strategy led to a +45% increase in click-through rates (CTR), a +35% reduction in cost per conversion, and a +40% increase in conversion rate. These changes significantly boosted their lead quality and reduced their overall marketing spend.

An Australian e-commerce retailer struggled to achieve its target ROAS of 5× despite consistent ad spend across Google Ads and Bing Ads. The account was heavily reliant on Performance Max campaigns, limiting visibility and control. CPA remained relatively high, and budget allocation was not aligned with top-performing product categories, resulting in inefficient spend and suboptimal revenue growth.
Solution
We conducted a deep performance analysis and identified Shopping campaigns as the primary revenue driver. The strategy was shifted to a Shopping-first approach. Campaigns were restructured into category-level segments (AA/AAA, Button, Coin, Rechargeable Batteries) for better control. Budgets were dynamically allocated based on performance, ensuring higher investment in top-performing categories and improved efficiency.
Result
Conversions increased from 1,593 to 1,632 while CPA reduced from A$19.77 to A$16.01. Revenue grew from A$57,898 to A$62,409, and ROAS improved significantly from 1.84x to 2.39x. The optimized campaign structure delivered better efficiency, stronger returns, and a scalable performance marketing system aligned with business growth objectives.
