Yelp reviews are super for good clients, but not so super for those businesses who tend to get bad reviews because there is nothing you can do about them except respond professionally and ask others to keep posting good stuff about you.
Just search your business and if you have a YELP review you see how high it ranks in the search. So keep asking for good reviews, they help get your business out there in ways that are amazing. Make sure you first check your business on www.yelp.com. Go here for step by step instructions.
Then make sure to create yourself a personal Yelping account so you can review others too! Or you can review other businesses as your business.There are many marketing opportunities with this active site. I believe in helping promote our local businesses here every time I have a good experience and hope they will do the same for me! http://www.yelp.com/biz/market-insights-llc-trenton
