Drogerkovo’s 25,000-product cleanup drove a 463% profit increase

Do you have a massive warehouse, thousands of items, and the feeling that your Google Ads budget is vanishing into a black hole? Welcome to the club.

This is exactly what Drogerkovo.sk was struggling with (but they don’t have to anymore :D). This e-shop faced a major challenge: how to effectively manage a gigantic catalog within a Performance Max (P.Max) environment.

Maintaining profitability with a 25,000-product catalog is a monumental challenge. Typically, only a fraction of the inventory actually sells, while advertising for the rest of the warehouse needlessly burns through the budget.

We’re going to show you how we “cleaned up” this massive digital shelf so that every single item started contributing to the bottom line.

Originally, the account ran one large P.Max campaign for all products. By deploying the P.Max Labelizer, we gained an “X-ray” view of the entire catalog. Products were labeled based on real performance, and we took action.

We filtered products out of the original general campaign and segmented them into specialized campaigns for Ghost + Zero and OFF labels (campaigns created in March 2026).

Acts as the e-shop’s main engine. The Labelizer filtered out thousands of inactive items, “purifying” the campaign.
The result? A stable 290 conversions at an impressive 634.30% ROAS.

Previously the “invisible” part of the warehouse (23,580 items) that received no exposure.

By isolating them into their own campaign, they achieved an 862.55% ROAS – we brought dead inventory back to life and turned it into a profit machine.

A place for the “outsiders” who failed elsewhere. Through intelligent recycling with low bidding, we achieved a shocking 1,094.46% ROAS.

These four campaigns brought order to the e-shop, but the real “brain” is hidden behind the scenes. Every day, the P.Max Labelizer scans all >25,000 products and instantly decides which ones are worth pushing and which should be hidden.

By constantly cleaning up products based on their actual performance, the e-shop has significantly increased its earnings. Take a look at how the numbers have shifted since the start of 2026.

The tracking period from January to April 2026 clearly confirms that intelligent segmentation isn’t just about chasing turnover – it’s about brutally stripping away “noise” to protect the margin.

When looking at the total portfolio performance, the numbers speak for themselves: while costs increased by a controlled 40% (to a total of €9,326.14), we managed to generate revenue of €45,629.30 (a 62% increase) and skyrocket net profit by an incredible 463% to €2,081.16.

This success is built on total efficiency. While we started in January with a 324% ROAS, by March – thanks to precise labeling – we reached a record 619%, with the average return stabilizing at 489%.

Relevance followed suit: the Conversion Rate jumped from 2.85% to a peak of nearly 6%. The system stopped “guessing” and started serving customers exactly what they were looking for.

A look at the individual performance labels—where the Labelizer manages all 25,415 products in real-time—shows that every euro invested has its place:

We identified 19 elite products that are absolute drivers. Their profit grew by a staggering 25,732% and revenue by 2,736%. With costs under €1,300, they generated nearly €10,000 in revenue at a 758% ROAS.

This is an analytical masterpiece. A total of 23,580 products (93% of the catalog!) were previously ignored by Google’s algorithms. The Labelizer gave them a chance, and the result is breathtaking: the Zero segment saw a 1,479% profit increase, and the Ghost segment brought in €13,422 in revenue that the e-shop would never have seen without this tech.

These segments form the healthy core of the business. While “Helper” products increased profit by 6,261%, the “Core” items saw a 132% revenue increase at a healthy 433% ROAS.

The Labelizer also acts as a relentless guard for your margin. The system detected 26 items (OFF) generating a net loss of -€364. By isolating them immediately, we saved hundreds of euros. Simultaneously, we “recycled” the Loser segment, which miraculously maintained an 848% ROAS under minimal bidding.

To recap: running an e-shop with 25,000 items without proper segmentation is like searching a massive warehouse with a tiny flashlight – you only see the three boxes at your feet.

The BlueWinston Labelizer turned on the floodlights for Drogerkovo. It identified potential in 93% of the catalog that was previously dormant, isolated the “Stars” for maximum profit, and organized the “Outsiders” so they stopped burning the budget

In just a few months, Drogerkovo achieved a leap in profit that others only dream of. And no, it wasn’t luck. It was pure mathematics, refined segmentation, and the right technology.
