The client
Our client is an Australian online lighting retailer selling lighting, globes and ceiling fans from a range of leading brands.
The challenge
With tens of thousands of products, the retailer’s Shopping and Performance Max campaigns risked spreading budget across low-value items. The account needed to put spend behind the products and brands that drove profitable sales.
What we did
Cut low-value products
excluded products under $20 from Shopping and Performance Max, reviewed weekly, so budget went to items worth advertising.
Budget behind profit
moved budget into high-profit campaigns and scaled spend up and down with demand, including holiday periods.
Cleaner purchase tracking
consolidated revenue tracking onto a single purchase goal, so bidding optimised for real sales.
Feed and account health
fixed Merchant Center and policy issues quickly and refreshed Performance Max creative.
Brand and product reviews
launched dedicated campaigns for key lighting brands and ran proactive 45-day product reviews to find new winners.

Why it worked
