How Perfetto.sk and Boosters Agency Crafted the Recipe for Google Ads Success

Achieving a 636% Profit Surge on a 15% Margin

Selling authentic Italian pasta, specialty coffee, or honest olive oils is a delightful mission. Italian gastronomy has a massive following in Slovakia, but with a narrow 15% profit margin, the e-shop Perfetto.sk and marketing agency Boosters couldn’t afford to let their ad budget boil over.

In the online grocery space, every cent poured into Google Ads must translate into tangible bank revenue – not just piles of clicks that leave you empty-handed.

Perfetto.sk is a Slovak e-shop catering to foodies and Italy enthusiasts alike. Their catalog is packed with “Made in Italy” goods, ranging from pasta and household products to authentic pizza ovens. In short, it’s a place where you can pack the essence of Italy straight into your shopping cart.

From a business perspective, how do you evaluate the collaboration with Boosters and the rollout of P.Max Labelizer?
We have been partnering with Boosters long-term and truly appreciate being able to openly address not only positive outcomes, but also bottlenecks and the raw numbers. Given the low-margin nature of our inventory, flying blind with ad spend isn’t an option. Labelizer introduced clear structure to our product catalog, which suited us perfectly. We can finally identify which products drive volume and which merely drain spend. What pleased us most was seeing neglected products – which previously sat around without a single impression—finally gain visibility and reach customers. We continuously cross-reference advertising platform metrics against our actual e-shop turnover to verify that performance holds up in reality. We are heading in the right direction and look forward to continuing this partnership.

Who Drives the Campaign Performance?

Boosters.sk is an ambitious Slovak marketing agency focused on bottom-line numbers and scalable e-commerce growth rather than empty slide decks. They specialize in driving measurable performance, executing efficient PPC management, and fueling strategic development for e-commerce brands.

The Problem: When P.Max Cooks without a Recipe

Standard Performance Max campaigns operating without granular segmentation behave like a chef tossing every ingredient into a single pot, hoping for a Michelin-star meal. Left unguided, Google tends to favor a handful of top-performing items – funneling the lion’s share of the budget into them – while hundreds of other potentially profitable products gather dust in the warehouse without securing a single click.

In an e-commerce model operating on a 15% margin, this lack of control is an expensive gamble. Perfetto.sk needed to stop subsidizing dead-end clicks and draw a strict line in Google Ads between profitable items and wasteful ad spend.

As an agency, what was your biggest hurdle when managing P.Max campaigns for Perfetto.sk prior to deploying Labelizer?
With a 15% margin catalog, the primary risk lies in disproportionate budget allocation. Running a single P.Max campaign across an entire inventory directs the bulk of ad spend toward a narrow cluster of products with historical conversion data. Meanwhile, a substantial portion of the catalog receives zero impressions, making it impossible to evaluate performance. The secondary issue centered on target ROAS. Perfetto operates with a 750% account-wide ROAS target, but applying a single target across an entire campaign fails to account for product-level variances. Top-tier products become throttled, while underperformers are subsidized at their expense. Manually reallocating products at this catalog scale is unsustainable due to daily fluctuations in performance.

The Solution: When Boosters Deploys a Secret Weapon

Boosters took charge, balancing refined strategy with decisive execution. Their specialists knew that surviving on a 15% margin required more than blind faith in Google’s automation – achieving truly bellissimo results demanded clear strategic direction.

Bidding arrivederci to wasted ad spend, they implemented P.Max Labelizer by BlueWinston. The tool established an automated system across the product catalog, categorizing items by real profitability:

Star, Helper & Core: High-performing, proven assets were granted priority budget allocation and greater leeway to maximize profit potential.
New: Recently added catalog items that needed to build baseline market data before Labelizer dynamically reassigned them into their respective performance tiers.
Ghost & Zero: Dormant stock and zero-impression items were isolated into dedicated campaigns to finally gain bidding traction.
Off & Loser: Chronic spenders that previously burned ad budget were reigned in with strict bid caps.

How did P.Max Labelizer provide the most leverage in your optimization workflow?
Labelizer automatically segments products into campaigns based on live performance data, enabling us to set custom budgets and targets for each tier. Proven profit drivers receive priority spend, while inefficient products are capped at tighter thresholds while remaining live in the catalog. We assess the 750% target at the overall account level rather than campaign by campaign, meaning lower-tier segments can temporarily run below target if balanced out elsewhere—eliminating the need to evaluate products individually. Our role shifted from manual sorting to higher-level management of budgets, data feeds, and creatives.

Numbers That Taste the Best

Backed by Boosters’ strategy and BlueWinston’s automation, the account delivered decisive 30-day metrics:

Total Revenue from Labelizer Campaigns: €16,771.18 (+118% increase)
Net Campaign Profit: €573.01 (+636% surge)
Average ROAS: 863.3% (+41% increase)
Conversion Volume: 2,275 completed checkouts

How the Individual Campaigns Performed

Parent Campaign (Star, Helper, Core and New labels): The core engine of the account. High-margin, vetted products operated with priority budgets, while the New label gathered data to funnel arrivals into appropriate tiers. Result: Generated over €4,700 in turnover at an exceptional ROAS above 1,500%.

Reviving Dormant Stock (Ghost and Zero labels): Products previously languishing in P.Max without a single impression were separated into their own campaigns, unlocking visibility and generating over 100 net-new conversions.

Halting Budget Drain (Off and Loser labels): Strict controls placed on historically unprofitable items produced the most surprising turnaround: instead of burning budget, they yielded over 1,900 purchases at negligible acquisition costs.

Summary

The collaboration between Perfetto.sk, Boosters, and P.Max Labelizer highlights the impact of structured e-commerce marketing. By removing dead zones from the catalog, cutting wasteful ad spend, and unlocking dormant inventory, the strategy turned hidden capacity into realized profit.
