PAY PER CLICK

Pay per click is an internet advertising technique used n websites in which advertisers pay only when their ad is clicked. In this technique advertisers bid on the keywords relevant to their target market. The providers charge a particular amount on per click basis.

Websites that utilize PPC ads 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 ads, and appear adjacent to or above organic results on search engine results pages, or anywhere a web developer chooses on a content site.

Although many PPC providers exist, Google AdWords, Yahoo! Search Marketing, and Microsoft adCenter are the three largest network operators, and all three operate under a bid-based model. Cost per click (CPC) varies depending on the search engine and the level of competition for a particular keyword.
