If your business has a location then you should use Google My Business. It’s a FREE service so there is no reason not to, you don’t even need a website.
The first thing you need to do is go to Google My Business. You might find that your business is already listed and that you need to claim it as yours. Google will make you confirm your business either by sending you a code to your business address or calling the business phone number.
You can add various details about your business including opening hours, phone number, website and photographs plus select the type of business category you are. You can now even add a post to your Google Business Page.
