By default you setup one tracking id which will be used for generating your affiliate links.
But there might be a situation where you want to replace the tracking id. This allows you to measure and compare different product placements, templates etc.
How can I set a custom tracking id?
This can be done easily by adding the attribute
tracking_id to any standard shortcode and passing your custom tracking id as follows:
e.g. single/multiple boxes
[amazon box="ASIN" tracking_id="my-custom-id-20"][
e.g. bestseller lists
[amazon bestseller="smartphone" tracking_id="my-custom-id-20"]
e.g. comparison tables
[amazon table="ID" tracking_id="my-custom-id-20"]
