48x ROAS in the Glamour Days promo campaign

Introduction

As Bosch’s Hungarian e-commerce partner, we handled the promotional management of small and large electrical appliances, primarily kitchen and laundry-related devices, during the Glamour Days period. The goal was to support a nationwide, few-days-long sale with digital advertising, maximising the revenue realised over the campaign period while strictly holding a 20x target ROAS.

The campaign period analysed: 9–12 October 2025.

Challenge

The starting position was made harder by several mutually reinforcing factors: the client had little experience running promotions that last only a few days, the available budget was low, and there was no pre-campaign, the standard practice before short sales for building up demand.

On top of all this came holding the strict 20x ROAS target, in an environment where set-ups that need a quick learning phase do not always pay back over a short run time. Together these posed a serious risk to managing both efficiency and total spend.

Solution

We built the strategy on the coordinated use of two platforms. On the Meta side we launched a conversion campaign with general, non-product-specific creatives, because in our experience these perform more consistently in a short promotional window than narrow product- or category-specific ads.

On the Google Ads side we worked in several layers: we set up a Performance Max campaign in both a feed-only and a creative-asset-enhanced version (thanks to the wide awareness of Glamour Days, the creative assets worked particularly well here), and we ran Search campaigns on the historically strongest product categories and on brand search. We directed traffic to a dedicated landing page to keep the conversion path as short as possible.

We optimised bidding for a Maximize conversions strategy: over a short run time this proved the most reliable, since value-based bidding typically needs a longer, multi-day learning phase. We allocated the budget by performance, at roughly an 80% Google Ads to 20% Meta split.

Channels and tools

Summary

The outstanding result came from the coordinated architecture of Meta and Google Ads, the dedicated landing page and a bidding strategy optimised for short-run promotions, all working together. The general creatives delivered steady performance, while Performance Max and Search efficiently covered both intent-based demand and automatic reach expansion.
