I am beginning to receive phone calls from my yelp.com listing. Two old recommendations appear on page one. I have 7 more outstanding recommendations but you can only see them if you click on the link to them.
I don't pay anything for this advertising!
I use yelp on my smart phone & I signed up for this free listing years ago. It is finally starting to generate leads.
