Performance ads for an online fashion store with a seasonal sales target and a fixed budget. Ran Meta and Google campaigns with prospecting kept separate from retargeting of product viewers and abandoned carts, set up e-commerce events (view, add-to-cart, purchase) in GA4 and Conversions API with order value, tested creatives weekly and focused spend on the highest-margin products. Result: 30% above the seasonal sales target with the same budget.
