Deep linking is linking to the specific interior page or product on a Merchant's site that your visitor is interested in (as opposed to just linking to the home page of the Merchant).
By deep linking to a specific product, an Affiliate can largely eliminate the problems associated with navigating a Merchant's website. By taking the visitor directly to the information that they desire, you greatly increase the chances of converting that visitor into a sale.
Choose deep linking enabled or disabled. Deep linking enabled allows the affiliate to adjust the destination URL and direct traffic to another section of your website.
