You can determine how much a conversion may cost. Thereby, it's important not to differ strongly from the historical costs per conversion because this might lead to a negative change in your performance.
You can set a cost per conversion goal independently if you convey conversion values to Adspert.
If you convey conversion values, it is up to you if you convey your profit or revenue. Learn more about conversion values and goals in Adspert.
