A great testimonial includes the following elements:
- The specific services you provided to the client
- The specific results he/she realized after working with you
- Whether or not he/she would recommend you to others
- The client name (first and last name is best; first name and last initial is acceptable)
- Client location (city/state)
- Photo of the client, if he/she has one and is agreeable to posting it
Here's a template you can use to ask clients for a testimonial:
Thank you again for the opportunity to work with you on your job search. I am happy you got the job!
I would appreciate the opportunity to post your results on my testimonials page. Would you be willing to write a few lines telling prospective clients how my services helped you in your job search? I would be most grateful.
