The ads were meant to be paused, yet they cost me about CZK 20,000.
When the Mincmistr store paused orders for a week, much of its paid traffic kept running. Korzaro helped uncover the discrepancy and recover the money.

Orders were paused. Ads kept running.
What Korzaro gave meKorzaro showed that ads kept running through the agreed pause and helped me recover roughly CZK 20,000.
We went to a trade fair and paused orders for a week. I asked the agency to pause the campaigns. They believed they had done so, but part of the setup had been missed.
I probably would not have opened Google Ads myself because I had no reason to check work that was supposed to be done. Even if I had, I would not have known where to look for the problem. Korzaro showed me afterwards that most paid traffic had continued and roughly CZK 20,000 had been spent unnecessarily.
We reviewed the specific discrepancy together and the agency refunded me. The shared view helped us fix what had been missed during the pause.
Promotion
7 daysThe item sold. Its ad remained.
What Korzaro gave meKorzaro showed where we were paying unnecessarily for ads on sold items and channels without orders.
Mincmistr sells collectible coins. Most pieces are unique: once sold, the exact item cannot be offered again. I would have struggled to keep track of whether an ad still pointed to an item that had already sold. Korzaro helped us spot exactly those ads.
I also lacked a clear view of what Zboží.cz and Heureka were bringing us. The combined data showed that they were unprofitable paid channels for our catalogue: they brought in no orders while still generating costs. We decided to switch them off.
Watchers
MincmistrAds point to sold-out items
For one-of-a-kind items, check whether active ads still lead to products that have already sold.
Connected data helped improve more than ads.
What Korzaro gave meKorzaro put the important figures in one place, so I know where to start and what to check.
We had advertising, SEO, Search Console, product, content and other channel data, but it was scattered. On my own, I would have struggled to see where to start and how the pieces connected. Korzaro brought them into one context; with Codex, we used that view for a thorough store audit and found a range of concrete improvements.
We also prepared a sharper PPC brief. The agency had not had all that context available in its work; now we could bring it into the conversation. I no longer have to spend five minutes finding basic traffic figures in Google Analytics because they have moved it somewhere else again.
Store overview
An opportunity I could not see in the usual reports.
What Korzaro gave meKorzaro revealed the value of registered customers; after the changes, their orders doubled.
The store held the order data, but the usual Shoptet reports did not show me how registered and unregistered customers differed. I could not see the size of the opportunity I was missing. Korzaro showed that our registered customers spend almost 70% more per order and buy more often.
We then worked to give visitors more reason and an easier path to register. After those changes, the number of orders from registered customers doubled. We will see the longer-term effect on revenue.
Now I know what to ask the agency
Korzaro gives me specific questions for the agency and other specialists. Advertising is no longer a black box to me: I can see where costs arise, what they deliver and what needs checking. That helps us have a more useful conversation and decide together what is worth paying for.
