Definition:
An effective way to gain new customer referrals, but the key is to provide a pleasurable experience to existing customers to elicit a response that allows them to share your products or services with their contacts.
Expectations:
Due to the unreliable nature of word of mouth, it is hard to create concrete expectations. It is typically up to the customer to make this happen.
Examples:
Referral programs, informal conversations with existing clients to gain leads, presentations with valuable information.
Frequency:
Since this method is not very reliable, it is very important to do it on a consistent basis to keep the continuity in the prospects that come into the funnel.
