This document discusses how membership organizations can identify and manage advocates within their own membership data. It explains that there are two types of advocacy - active advocacy, where satisfied members will recommend the organization to others, and passive advocacy, where members' compliance with similar members' behaviors can be used as a template. The document recommends collecting the right member data and engaging members in the relationship to progress them to advocacy. It also suggests applying research data to the membership database to better segment members and identify the five types of constituents, including advocates.
