Driving traffic to multiple pages of your website, or even multiple websites can be done using a couple different methods.
Option 1: Marketing Groups
Option 2: Affiliate Defined Traffic Delivery
Create a different marketing group for each of your website/product pages you want affiliates to deliver traffic to. This can even be different/multiples websites. Set the Alternate Incoming Traffic Page for each of those groups.
Now upload and create marketing materials for each of these marketing groups. When your affiliates login to get a marketing piece, they will choose which marketing group to get it from and the traffic they deliver will go to the defined Alternate Incoming Traffic Page set for the chosen group.
Using this method, affiliates can define the page they are driving traffic to directly in their affiliate links. To enable this feature, go to General Settings then Advanced Tracking in your iDevAffiliate admin center. You will fine the Allow Alternate Incoming Page Links setting. Select Yes to enable it. Affiliate can now login to their accounts and click on Alternate Incoming Page Links and have the opportunity to use the Automated Link Creation or Manual Link Creation feature which allows them to append a URL to an existing affiliate link.
