The Simple Woo Affiliate Tracking simply (ha!) tracks the sales driven by any URL appended with a ‘refid’.
For example:
www.yoursite.com/?refid=lj419275070985lkhj0
Any body who clicks through that URL and buys a product through your store will have that unique ‘refid’ attached to their order.
This allows you to add your own refid to any link you want to distribute. You can export the number of sales assoicated with the id at any time through “Tools”>”Simple Woo Affiliate Tracking” into a .csv file.
How it works:
The plugin detects the ‘refid’ appended to the URL and stores it in a cookie. During checkout, a ‘refid’ field is added to the checkout form (in a hidden state), and that field is set by plugin Javascript.
