Try This: go to google maps and type in your zip code. OK now you have a map of your neighborhood. Now enter the word dentist. What shows up? Is your office listed? Are there any links to your web site? Any user reviews? Anything under the more info tab?
If you are signed up with a google account you can “Claim” the listing and add all kinds of additional information that a patient could use to find your office and choose you as their dentist. You can add photos, videos, web links and key words.
If you are interested, like using technology and have the time you can do it yourself. Or you can contact Sesame Communications. They provide the service to set up your google presence with both free listings like the map search or paid pay per click (PPC) options.
