More sales from 21% less Google Ads spend.

The problem

Reactiv Supplements is a New Zealand sports nutrition and supplement retailer offering locally sourced protein powders, creatine, health supplements and sports nutrition products. After more than 10 years in the account, the job is not to spend more — it is to keep making the budget work harder.

The brief

Improve efficiency and generate the strongest possible return from the available Google Ads budget.

The result

Comparing February–December 2025 with the same period in 2024, Google Ads delivered 12% more conversions on 21% less spend (about $2,800 less) and a 29% lower cost per conversion. Tracked conversion value held virtually flat. ROAS rose from 13.23x to 16.86x, and average cost per conversion fell from $8.48 to $5.99. More sales, from considerably less advertising spend.
