If you are open to suggestions, you can use our tool ReviewPete( https://reviewpete.com/) , which not only enables in getting positive reviews on Facebook, Google and Yelp for Local Businesses but also prevents negative reviews in the first place.
ReviewPete sends a request to the customer for providing feedback via email / SMS. When they click the link they are directed to a form where we ask if they would recommend ReviewPete.
If they say yes, we show them another window that leads them to FB, Google or Yelp.
But if they say no, it redirects them to a hosted form where they can provide their feedback. This way, we avoid negative reviews and only let positive reviews pass on to where it matters
