Seller's Concern

When launching ads in a new marketplace for the first time, the biggest obstacle is the absence of data. Without any prior operational history or performance benchmarks to reference, the priority isn't to invest heavily from the start — it's to validate efficiency first, then consider scaling.

Celimax is a K-beauty brand known for its commitment to ingredient transparency and skin irritation minimization, building recognition in the sensitive skin and everyday skincare categories. Entering the UK market for the first time, Celimax needed to establish a stable, efficient ad structure from day one.

LG Optapex Solution

Even as a first-time launch in a new marketplace, Celimax was able to achieve strong early results. Here's how:​

① Algorithm-driven optimization that works — even in a new market

With virtually no operational history in this market, Optapex's optimization algorithm began generating early results from the start. From the first days of ad delivery, CPC stabilized quickly, while impressions and sales followed a steady, upward trajectory.

② A structure built on efficiency, not just spend

Even with a conservatively set initial budget, TACoS was maintained at an exceptionally low level of approximately 2%. This wasn't simply a result of limited spend — it reflected a structure designed to minimize inefficient traffic and concentrate investment in high-conversion areas, creating a lean ad operation from the beginning.

③ Performance builds trust. Trust drives expansion.

Celimax began with a single Optimization Set as an initial test. As strong results emerged, the team gradually expanded operations — scaling up to 8 sets, with performance growing alongside each step.

Results

While ad spend increased by 123%, total sales grew by 493%. ROAS improved by more than 3x, and TACoS was maintained at approximately 2% — well below the industry average. (January-March 2026)

Starting from a market with no prior data, Celimax achieved efficiency and growth at the same time.

“Entering a new market, we wanted to lower the barrier to launching Amazon advertising. Through Optapex, we were not only able to build an efficient structure, but also achieve meaningful improvements across key metrics including TACoS, ROAS, and CPC.” — Celimax Brand Manager

Conclusion

Entering a new market. No data to rely on. The weight of risk. These are the realities every brand faces when launching Amazon advertising in an unfamiliar marketplace.

Celimax lowered those barriers with Optapex — building a stable, results-driven structure from the very first campaign.

No matter which market you're entering, you can get it right from the start.
