Great question — answering as the UphillTech team:
Be sure you use the <address> HTML tag and place your address in it. If you don't want to use your home address use a PO Box or a UPS store address (be sure to have a box there). Place it in the footer of your website and on your contact page. Also, add your business to Google Places .
