Challenge

A premium beauty brand faced the challenge of launching a new fragrance line in a competitive e-commerce market. They needed to ensure a strong market entry, maximize online sales, and maintain a low CPA to achieve a high ROAS. The brand sought our expertise to manage a pilot campaign, with the goal of testing the e-commerce waters while ensuring cost efficiency and a successful product launch within the first 90 days.

Solution

We implemented a comprehensive multi-channel marketing strategy, including targeted keyword search campaigns, advanced retargeting, and geofencing around luxury retail locations. To optimize cost efficiency, we meticulously managed CPA through real-time bid adjustments and strategic budget allocation. Data-driven approaches like A/B testing and real-time analytics allowed us to refine our strategy, ensuring that we captured significant market share and drove substantial e-commerce conversions.

Result

The campaign generated 30.4M impressions and achieved 9,973 online sales within 90 days, driving over $523,575 in e-commerce revenue. We secured an exceptionally low CPA of $3.40, far below industry averages, and delivered a 4.1x ROAS. The success of the pilot led to our agency being entrusted with the full display and programmatic advertising budget, further optimizing the campaign and setting a new benchmark for e-commerce launches.
