Google offer you the opportunity to be found by local searchers, on the front page of Google SERP’s. You will need a Google+ account followed by a Business Page for your business.
Once you have added all of your business details, the geographical area you cover, opening times, and the suitable categories that you are applicable to, you will be asked to verify your account.
Google do this to limit the amount of fake and spam accounts on their system, and you will need to wait a couple of weeks for them to send you an authorization code via snail mail.
Once you have entered your code, your listing will be live and you will begin to appear for relevant keywords in the area you selected.
You can then begin to improve your rankings in Google Local search by getting your customers to leave you reviews on your Google+ page.
