How Signature Works

LinkShare Signature tracks commerce to the transaction level of each individual member, organization, or sub site through the use of the Member ID field.

The MemberID field is denoted by a "&u1=" that Signature affiliates must append to the merchant link codes provided in their LinkShare account. The value following the "=" sign represents the specific member, organization, or sub site created by the Signature affiliate. The MemberID field can be up to 72 alphanumeric characters in length.
