There are hundreds of directories online that list local businesses along with general information and, in some cases, customer ratings. An individual business listing is called a “citation”. Once on a directory site, searchers can use keywords to find the various businesses in the niche, such as dentist, dental office, teeth whitening, dental implants, etc. Some people prefer to use these lesser-known websites to research the details and rankings of the business they are interested in. Below is an example of a small directory that has not gotten much attention by various search engines that list Smileworks General & Cosmetic Dentistry. The larger directories that you might be familiar like Yelp, Foursquare, and Manta are not listed.
