This just in: trulia now has recommendations as well. My suggestion is, when you send your “congratulations on your closing” message to your client that you rotate which link you send them to recommend you or review their experience with you. I.E. Today to Mrs. Jones I will send my yelp.com profile link and tell her to please click “write a review” in the middle of the screen to write a brief testimonial of her experience working with me or just click a star rating. Next week when Dr. Brown closes I will send the email with my zillow profile link and ask that he fill out the quick star rating review. Same with linkedin and now trulia. By doing this, I maximize all resources and webpages available and further build my online presence. Plus I allow potential leads on any site to see a positive review straight from the horse’s mouth.
