It is a marketing program, where you can participate as an affiliate. Affiliates receive commission for generating sales for the affiliate program host (in this case, XYPNET). All affiliates are provided with various ads and tracking code for placement on their websites, in their email campaigns or in search listings. Whenever a visitor uses these ads/links to generate a sale on the host site, that transaction is tracked online. If a product or service is purchased, the customer pays the host directly, and the affiliate is paid a commission for that sale!
