Google has been measuring customer behaviour and analyzing what triggers a purchase. In May, 2016, Google disclosed that 76% of people that search on their smartphone for something nearby ending up visiting a business within a day. Even more important, is that 28% of those searches result in a purchase. This is good news because, if you have not done so already, you can potentially get your goods and services in front of additional consumers by optimizing your business for local search!
