# Methodology
- Source: the client's eMAG ADS panel (orders attributed to campaigns, cost, order value, clicks, impressions).
- Relative timeline: M1 = first month of measurement; no calendar dates, seasonality described in words.
- Reference month = last month of the series; ROAS, ACOS, average order value and order value come from it.
- ACOS (campaign cost / order value) given before ROAS - it is the metric from the eMAG ADS panel.
- Statistical data rounded for anonymisation (orders to 10-100, amounts to thousands of RON, ROAS to 0.5-1).
- Account turnover = estimate assuming that sales from eMAG ADS account for 30-50 % of the account's sales.
- Account size by the best month of the series: up to 100, 100-500, over 500 campaign orders a month; orders from eMAG markets are added up.
- Anonymised data: category, market and account size without the seller's name.
- Campaigns and catalogue: results are the effect of eMAG ADS campaigns and parallel work on product pages; we do not separate these influences in the numbers.

# Starting point

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.

# What we did

1. **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.
2. **Bids calculated from margin** - 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.
3. **Budget down together with demand** - 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.
4. **Order in the account** - 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.

# What this teaches

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.
