A response channel is the communication medium that is used to allow a recipient of a message or media to communicate back to the media broadcaster or sender. Informational documents may use a mix of response channels including download registration, resource links and contact points for requests for additional information.

Download Registration - Download registration is a process whereby a person who is requesting to obtain access to content (such as a document download) must provide identification information before being granted access to obtain the document or media. Download registration processes vary and may be as simple as providing a name and valid email address or as involved as setting up a user account that requires the completion of detailed user information.

Resource Links - Resource links are resource identifier addresses (web addresses) that point to the locations of additional resources which readers may find helpful. In addition to providing value to the readers, the tracking of resource link selections can provide the content provider with an indication as to the amount of interaction readers have with documents (number and location of reference links selected), and the key topics of interest (which links were selected).

Response Inquiries - Response inquiries are requests for information that result from the receipt of a document, brochure or other media item. Response inquiries can be tracked by using a unique contact identifier, such as a telephone number or email address, which is specifically associated with a document contact point.
