As per PAAPI's License Agreement Point 4.(e): You will not, without our express prior written approval, use any Product Advertising Content on or in connection with any site or application designed or intended for use with a mobile phone or other handheld device (which prohibition does not apply to any site that is not designed or intended for use with such devices but that may be accessible by such devices, such as a non-mobile-optimized site accessed via an internet browser on a tablet device), or any television set-top box (e.g., digital video recorders, cable or satellite boxes, streaming video players, blu-ray players, or dvd players) or Internet-enabled television (e.g., GoogleTV, Sony Bravia, Panasonic Viera Cast, or Vizio Internet Apps).

Guidance:

The above statement is almost exclusively applicable to mobile apps. Mobile Apps are currently not approved to have advertising links to Amazon without signing an amendment. Without the approval, building links to Amazon on mobile apps amounts to a fraud and any violating associate account will be blocked from accessing PAAPI.

In most cases, with exception of sites designed or intended for use with a mobile phone or other handheld device, you are allowed to display advertising links to Amazon to users visiting your site on phone.
