Two campaigns instead of many
One manual keyword campaign on the whole catalogue and one Product & Category Targeting campaign on bestsellers. No fragmenting the budget across tests that, given the goals set, would have made them harder to reach.
A Pet supplies account on eMAG Romania: equipment for pets with clearly seasonal demand, where it is easy to overpay for sales once the season passes. We show how to keep advertising cost at a few percent of sales for seven months.
The seller entered eMAG with a small catalogue and a simple goal: to sell at a profit, not "at any price". The advertising budget was limited, so every leu had to work. A small catalogue has one advantage: we could polish every product page before the budget started - and that was part of the same work, not a separate project.
This is a category with clear seasonality: demand rises in the cold months and falls in the warm ones. You can see it on the chart - over 300 campaign orders a month at the start of the series and about 130 at the end. That is not an account failure, it is the market.
The measure of success was therefore not the number of orders, but keeping ACOS at a few percent over the whole period - including when demand drops.

| month of cooperation | campaign orders |
|---|---|
| M1 | ~300 |
| M2 | ~300 |
| M3 | ~350 |
| M4 | ~250 |
| M5 | ~160 |
| M6 | ~140 |
| M7 | ~130 |
The decline in the second half of the series is the category's seasonality, not the effect of the campaigns - over that time ACOS stayed at about 6 %.
One manual keyword campaign on the whole catalogue and one Product & Category Targeting campaign on bestsellers. No fragmenting the budget across tests that, given the goals set, would have made them harder to reach.
We calculated the maximum cost per click from margin and conversion, not from the panel's suggestions. A click-to-order conversion of about 12 % made it possible to keep the cost of sales low.
When the season began to pass, we did not push with budget. The campaigns got lower limits, and ACOS stayed below 6 % - instead of rising, as usually happens after the season.
Two active campaigns with clearly divided roles: the manual one drives the whole catalogue, Product & Category Targeting boosts the bestsellers. This structure lets us work every day on what actually sells - bids, keywords, exclusions and product pages - instead of spreading attention across many campaigns.
For every leu spent on campaigns the account gets close to 18 lei in orders, which means advertising costs about 6 % of sales. With a small budget, it is exactly this ratio that counts.
A small account does not need many campaigns. It needs a well-calculated bid and two campaigns that get full attention.
Seasonality has to be accepted, not "made up with budget" - trying to keep volume after the season usually ends with an ACOS twice as high.
A high click-to-order conversion (here about 12 %) is most often down to the product page and the price, not the advertising - which is why we worked on the pages alongside the campaigns. Advertising only brings traffic to where the page already sells.
