I am trying to diagnose how one particular competitor is smoking us in local rankings. I came across a text field “Service Details' within Google My Business Services. This allows me to put in a brief description of each service we offer. My thought is that this could be a good place for keywords. That said, the descriptions are not public facing (or to the best of my knowledge) so I am reluctant to do all the work for nothing. I am wondering if anyone has filled these out and if there were any noticeable results. Any insight is appreciated
