The client and the goal

The client runs an online lingerie shop. We keep the brand anonymous. The shop already had advertising strategies in place and wanted more: mainly, to scale its campaigns.

The question was how to scale without simply paying more. Our answer was to change a handful of things and let the whole account work differently.

The challenge

The lingerie market is highly competitive, and advertising costs were rising. Earlier strategies had delivered ROAS 536%. The client wanted more.

Scaling meant finding the spend that produced clicks but not sales, and focusing on the audiences most likely to buy.

What we did

Four changes did the work. Together they reshaped how the shop's Performance Max campaigns spend and who they reach.

Precise targeting
We split campaigns by product category, seasonality and customer profile, so each group got its own focus.
Eliminating inefficient spend
We identified the campaigns that generated clicks but did not translate into sales, and dealt with them.
Performance Max optimisation
We used Google Ads automation under the agency's control, applied to precisely defined audience groups.
A/B testing
We tested messages, creatives and calls to action in different combinations to see which worked best.

What drove the results

ROAS. At 1066%, every €1 spent on ads returned more than €10 in revenue. ROAS (return on ad spend) is revenue divided by ad spend. Earlier strategies for this shop had reached 536%.

Sales. Sales grew 280%. Precise targeting increased conversion.

CPA. The cost of acquiring a customer fell 40%. Eliminating unnecessary costs made the budget work harder.

Good advertising is not a bigger budget. It is a better strategy.
