One of our clients SIGNCO www.teamsignco.com has been listed in the Google Business Directory for a few years. Recently I confirmed their business with the phone call and entered the confirmation code, and all was good. I seen that I could enter a description and also a photo, but I was scared to change anything too much or it might effect their page rank when you search "signs stockton, ca". Would it be better to add this info? Should I upload their logo? If so what is the best size? Any info on this Google Business Directory would be a great help!
