Additional marker (sub id)
An additional marker (sub id) is a parameter that allows tracking sales separately for each traffic source/promo material.
Say that you are using several different promo materials on different parts of various sites: a search module in the sidebar, links to ticket searches in site articles, a banner in the footer, etc.
To get separate statistics for each promo material, you need to make use of additional markers.
The maximum length of an additional marker - 32 characters.
Statistics on additional markers (sub id)
For statistics on additional markers, go to Report -->Sales report. Information can be grouped by markers.
Example: of how to place an additional marker in a link: http://www.jetradar.com/?marker=11111.sidebar, where “sidebar” is the additional marker.
In the form builder, the additional marker is set using a special field. You should enter only the marker in the field, without any additional characters. The marker can contain numbers, latin letters, underscores (_), and hyphens (-).
Creation of a text link is similar in this regard: an additional marker can be added to a link through the form builder on the affiliate account page.
