To identify the source of your sales (which links are performing better), a separate link identifier can be assigned to each link. For instance, if there are two buy links on your website, one in the product page and another one in the download page, you can track the source page by entering the following parameters:

AFFSRC=prodpage for the product page or AFFSRC=dldpage for the link on the download page (dldpage and prodpage are example strings only, you can use any combination).

If the buyer uses a link that includes the AFFSRC link identifier, the parameter will be included in the order notification email. The detailed report on the AFFSRC usage (Sales source report) is available in the Graphical reports menu.
