After you sign up for the program you will have access to a number of banner ads, text ads, and text links. Each ad type will have a "view sample code" link. When you select the link, a pop up window will open providing an example of the ad, as well as the necessary HTML to place the ad on your site (your Affiliate ID will be automatically included in the HTML). Simply copy the HTML and paste it into your site.
Whenever someone uses your text links or ads to open a new hosting account you are credited with the sale (provided that the new account is eligible for credit as per our terms of service). You can also simply provide your Affiliate ID to anyone you wish to refer. When they sign up for hosting on the Winhost site the order form will contain a field to enter your Affiliate ID. Again, providing that the account is eligible for credit, the new account will be credited to your Affiliate account once the sign up is complete.
