The most important step to building and maintaining a referral network is to ask for referrals. Many people are willing to refer you, but they may not know how, when, or who to refer you to. Therefore, you need to make it easy and clear for them to refer you. You can do this by creating a referral system that outlines the process, the incentives, and the expectations for your sources of referrals. For example, you can create a referral form, a landing page, a script, or a template that they can use to refer you to their contacts. You can also offer them rewards, recognition, or feedback for their referrals, such as discounts, bonuses, gifts, testimonials, or referrals back. You can also set goals, track results, and follow up with your sources of referrals regularly to show your appreciation and to encourage more referrals.
