It’s very important to have a network of professionals that you can refer your people to. All of those things that they need that you do not do. This could be a chiropractor, a massage therapist, a registered dietician, or even a good car mechanic.

Being able to help your members/clients solve a problem that they have is a great way to build social currency (being held in higher esteem). Which equals greater loyalty. So, yea! However, be careful who you refer people to. Every referral that you make is a reflection on you and your brand. As said, a successful referral increases the positive feelings that people have for you, but, a negative experience can have the opposite effect. You lose respect and loyalty.
Build your referral network by getting to know the people you intend on referring people to. Chiropractor? Go talk with them and get an adjustment. Massage therapist? Get a massage. Don’t refer unless you know what they can do. Sure, it will take longer to build that network, but your clients, the people you referring your clients to, and your brand will thank you.
Note: What got me going on this was that I was talked into joining this online referral group. As I made connections to other businesses, I kept getting asked to refer them when I really didn’t know anything about them. Referrals are precious. Use them only when you know that they will serve your people well.
