Customer advocates are not necessarily your biggest or most frequent buyers; they are those who have a genuine passion and enthusiasm for your product or service, trust and respect your brand, and are willing and able to spread the word about you. To identify them, you can ask customers if they would like to join your advocacy program or if they have already referred someone to you. Surveys, feedback forms, and social media polls can also be used to gauge their interest and satisfaction. You can use data and analytics to segment customers based on their behavior, engagement, and loyalty. Indicators such as NPS, CSAT, CLV, repeat purchases, retention rate, churn rate, referral rate, social media mentions, reviews, ratings, testimonials or case studies can also be used. Offering rewards such as discounts, freebies, upgrades, access, recognition or exclusivity can incentivize customers to become advocates. Gamifying your customer advocacy program with points, badges, levels or leaderboards may also help.
