PAY PER CLICK (PPC)

Pay per click (PPC) is an Internet advertising method being used on search engines, advertising networks, and content sites, such as blogs, in which advertisers pay their host company only when their ads are being watched and clicked. With search engines, advertisers typically bid on keyword phrases relevant to their target market. Content sites normally charge a certain amount per click rather than use a bidding system.
Websites that utilize PPC advertisements will display an advertisement when a keyword query matches an advertiser's keyword list, or when a content site displays relevant content. Such advertisements are called sponsored links or sponsored advertisements, and normally appear adjacent to or above organic results on search engine results pages.
