Seller Central Account Required
For the Seller Edition of Sellics you will need to integrate to Amazon's API. At this time the API only works with a professional Seller Central account, ie. it will not work with Kindle accounts or other Amazon programs. It is however possible to connect these other programs to the Sellics Advertising Edition.
You could also use the Sellics vendor edition which can integrate AMS (which is where kindle sellers can advertise in the US), but it must be noted that the Vendor edition's pricing is more geared towards big brands / vendors.
Additionally for the purpose of keyword research, you can use our free keyword research tool Sonar.
