How to ask for a referral
Make your request personal.
Targeted referral requests tend to generate a better response than mass emails or a general request on your website. Reach out to individual clients directly.

Options: (1). Try to target clients with whom you have a good, well-established relationship. If a client trusts you and is familiar with your work, they're more likely to give you a great referral.; (2). Identify the types of questions you want to ask the client. For example, you could ask : What kind of medications did you use? What hospital are you in? How many drinks do you drink? What is your healthcare insurance policy? Look online.; (3). Indicate a problem before offering the follow-up correspondence. Provide a concrete goal for the contact by offering a specific day, time, or place.; (4). Ask them in person about where they are, how often they contact you, what circumstances they are experiencing, and why they contact you. While you can ask to get a referral without calling, making requests in person also receives a much better response.;
The answer is:
(1).
