Supplements Online Store: How We Optimized Advertising and Increased Orders

Services

Challenge

Our client is a supplements online store selling a drainage drink for reducing swelling, detox, and weight control. The project was launched almost from scratch: there was no advertising infrastructure, no analytics, and no tracking. The goal was to bring the brand to market quickly and build a customer acquisition system through Google Ads.

Goal

Build a customer acquisition system through Google Ads, set up analytics, and launch sales quickly. Test demand for the key products.
