Around 18 months ago when Google Places for business became signifigant in organic search, early adopters had the chance to experiment with the new listings and work out what factors could help in achieving top ranks. One of the key principles that I discovered had came out of this, and still remains relevant now, is that synergy between your online presences is one of the best techniques you can use to rank higher for local searches. The basic concept is to ensure that your address and details across all your online properties remains constant. This way Google Places can determine the links between all the great online content you are creating and rank you sublimely for your efforts. Often, I notice small changes between such data, and it can mean the difference between ranking on Places in the top 7, or not ranking at all.
