Google provides some amazing stats within your Google Business Page so you can see how many people are not only viewing your business page but also taking action. It's called "insights" and you can see how many people are clicking on your website link, phone number and for those businesses with store fronts, driving directions.
When we talk to business owners and show them how to get access to their insights, they are always surprised how much traffic their business page is getting! All these people are also looking at the reviews for that business as well. So its important to have some recent Google reviews to convert these potential customers. Surveys show that 80% of consumers take action after reading a recent positive reviews by either clicking, calling or driving to that business.
