How many products should I advertise?
The number of campaigns that can be created should depend on the budget you want to spend. We calculate with approximately 10 EUR/USD/GBP per ASIN per day in order to determine the minimum budget needed. Of course, it is possible to add further campaigns successively after the initial setup, in case the budget cannot be spent.
Note: deviations might exist - there are products which could be advertised with much higher budget per day, and others, for which the search traffic is too low to spend such an amount. This is just a rule of thumb.
