What COS is
COS = cost of sale. It tells you what percentage of the revenue generated by your ads is made up of the cost of those ads. If you spend 400 EUR on ads and they bring in 4,000 EUR in revenue, your COS is 10%.
How to adjust your COS
Open Settings and click the Target COS tile.
The Target COS campaigns settings open.
Adjust the COS using the blue slider. The slider ranges from 1% to 50% in 0.5% steps. A higher value means a higher allowed advertising cost.
Watch the numbers above the slider, they update automatically as you move it.
Once you've set the desired COS, click Save changes.
Not sure which number to choose? You'll find how to work out your target COS in the article What target COS should I set?
⚠️ Please note: we recommend consulting us before changing the maximum campaign COS, just write to us via Support in the app. A COS set too low can cause a significant drop in your sales.
