Seasonal Retailer Achieves 350% ROAS with Dynamic Budget Management

The challenge

A seasonal online retailer with extreme demand spikes around key calendar dates faced a problem that manual campaign management couldn't solve: by the time budgets were increased in response to rising demand, the peak selling window had already passed. The business also carried finite inventory — over-advertising during a spike could generate orders that couldn't be fulfilled, while under-advertising left revenue on the table.

The approach

Seasonal products were separated from year-round lines and given their own campaigns, allowing entirely different strategies for each. Budget scaling was automated to respond to performance signals in real time, ramping up ahead of seasonal windows rather than reacting after the fact. Bidding was connected to stock levels so that as inventory depleted, spend automatically reduced — preventing the customer experience problems that come with advertising out-of-stock products. Location targeting was also tightened to exclude areas the business couldn't serve.

The result

350% ROAS during peak periods, with automated budget management removing the need for daily manual adjustments. The combination of seasonal campaign separation and inventory-aware bidding turned unpredictable demand spikes into a manageable, repeatable process.
