Most e-shops approach Facebook ads with a "throw in more budget, launch more campaigns" mindset. We did the exact opposite.
Picture this. You run a successful e-shop, great products for people with allergies, healthy margins. You pour money into ads and it sort of works. But you know it could be better. Because Meta Ads aren't about how many campaigns you can click together — they're about how clean the data is that you feed the algorithm.
That's exactly the challenge we faced with nanoSPACE.cz. January 2026 looked decent. Spend of 307,000 CZK (≈ €12,000), revenue a little over a million CZK (≈ €40,000), ROAS around 3.73×. Nothing to complain about, nothing to write home about. But we knew there was far greater potential dormant in that account. All it took was to stop fighting the algorithm and start working with it.
Where it started: an account smashed into atoms
When we first looked at the account, it resembled a teenager's bedroom. Loads of small campaigns, each living its own life, and the budget scattered across dozens of ad sets. And the algorithm called Andromeda? It was literally starving for consolidated data.
But the biggest problem lay elsewhere. A single campaign mixed products with wildly different margins. On one side, a hundred-crown toothpaste; on the other, a premium cream at eight times the price. And what does Meta do when you hand it a mix like that? It takes the path of least resistance. It starts bringing you cheap toothpaste conversions, because that's easiest for it. You cheer at the purchases, but profitability is crying.
January 2026: Ad Spend 307,000 CZK (≈ €12,000), ROAS 3.73×.
What we changed: less is sometimes a whole lot more
Instead of adding more campaigns, we picked up the scissors and started cutting. We built the strategy on four solid pillars:
1. Campaign consolidation
We merged that tangle into just 2 main CBO campaigns. Why? Because Campaign Budget Optimization works brilliantly when you give it room and data. Meta itself knows best who to show the ad to.
2. Split by margin, not by category
This was the "aha moment." Instead of dividing products into bedding and cosmetics, we split them into cheap and expensive. The algorithm could no longer take the easier route of cheap conversions. Bullseye.
3. Room for Andromeda
We scrapped narrow targeting. Broad targeting across Czechia and Slovakia, minimal restrictions. We gave Andromeda a hint, but let it roam the whole field. The result? More data, smarter learning.
4. Hunting for hidden gems
We kept running only what genuinely worked. The weak pieces we cut without mercy. And then we found a gem — a creative for cellucream. We gave it room and it rewarded us with an unbelievable 10.29× ROAS.
Numbers that speak for themselves
In February 2026 the magic began. We cut spend by a quarter, down to 230,000 CZK (≈ €9,200). You'd expect revenue to plummet, right? Wrong. Revenue dropped by a mere 2.6% to 1.12 million CZK (≈ €45,000). ROAS jumped to a beautiful 4.87×. The CBO campaign with the cheaper products even delivered a 6.80× ROAS and brought in 600 purchases.
But watch out — there's one critical piece of context. nanoSPACE doesn't feed revenue into Meta, it feeds profit. A 4.87× ROAS on profit works out to roughly 10–12× on revenue. For comparison: the Home & Garden industry average sits between 2.18–3.86× on revenue (and a good ROAS is generally seen as somewhere between 2–4×). So we're 3–5× ABOVE the industry average.
4.87× ROAS ON PROFIT = ≈ 10–12× ON REVENUE. We're 3–5× above the market average.
Year-on-year rocket: February 2025 vs. February 2026
Comparing February 2026 with the same period a year earlier, the e-shop's total revenue jumped by 59% (from 2.17 to 3.45 million CZK, ≈ €87,000 to €138,000). Total margin grew by 50% (from 920,000 to 1.38 million CZK, ≈ €37,000 to €55,000). Revenue from ads nearly tripled.
The trajectory over the course of the month was interesting too. Early February (W1) was in the learning phase with a 1.95× ROAS. In the second week (W2) the account woke up to 3.92×. The third week (W3) was an absolute high with a 12.36× ROAS. By the end of the month things settled at a lovely 5.43×. The algorithm simply needed to catch its breath.
| Metric | January 2026 | February 2026 |
|---|---|---|
| Spend (Ad Spend) | 307,000 CZK (≈ €12,000) | 230,000 CZK (≈ €9,200) (↓ 25%) |
| Revenue from ads | 1.15M CZK (≈ €46,000) | 1.12M CZK (≈ €45,000) (↓ 2.6%) |
| ROAS (on profit) | 3.73× | 4.87× (↑ 30%) |
What to take away for your own business
Campaign structure matters more than budget. We throttled spend by 25% and still increased efficiency and profitability. The problem often isn't that you're spending too little — it's how the account is built.
Andromeda needs to breathe. Merging into two CBO campaigns gave the algorithm the data it needed. The more campaigns, the longer and more painful the learning phase.
Steer by margin, not by category. This changes the rules of the game. If you mix products with different margins in one campaign, Meta will always bring you whatever sells most easily. And that's usually not what earns you the most.
Scale with sense. Find the creative gems (like our cellucream with a 10×-plus ROAS) and give them room. Switch off the rest of the ballast without mercy.
