The challenge

Studio BÜKI, a B2C e-commerce brand selling customizable children's books, needed to save time and resources while making its advertising genuinely profitable. The marketing effort needed structure, and the ad accounts needed to work harder.

The approach

Jade Antlers built an omnichannel program tuned for profitable scale. On Google, Dynamic Search Ads and exact-match campaigns ran alongside Performance Max. Facebook advertising used multi-funnel targeting with continuous creative optimization, and the LINE account was audited and restructured to perform.

Marketing consulting tied the channels into one strategy, and a disciplined weekly optimization rhythm compounded what worked.

The results

  • Return on ad spend reaching up to 541%
  • A 43% average increase in return on ad spend month over month
  • Total ad spend scaled to six-figure levels while staying profitable
  • A clear performance step-change within six months

The professional, timely, and data-driven service led us to quickly reach excellent profitability.

The takeaway

Profitable scale is a structural outcome. An omnichannel build, a restructured LINE account, and a disciplined optimization loop let spend grow without giving back the return.
