PPC for dentists, also known as pay-per-click advertising for a dental practice, is the process of running ads on digital platforms such as Google, Facebook, Bing, etc, where the dentist is charged for each time a user clicks on the ad. Other methods of charging exist, such as when the ad has been shown a certain number of times (i.e., number of impressions). Generally, clicking on the ad takes the user to a web page designed to elicit a response such as making a call to the dental practice or scheduling an appointment.
