Cost per click, CPC (ex. Google Adwords)
Cost per click is the sum paid by an advertiser to search engines and other internet publishers for a single click on their advertisement, which directs one visitor to the advertiser's website.

Description
Cost per click is based on principle of paid positioning according to traffic. The advertiser pays only if the web surfer clicks on the advertiser's publicity space. The more keywords are in demand, the higher the price. It's therefore very important to choose the keywords very carefully in order to obtain an optimal cost/performance ratio.
To distinguish cost pre click advertisement from organic results, search engines often put advertisement under a rubric of "Sponsored links" or "Commercial links" like Google Adwords.
Cost per click is used as a complement to referencing (SEO) and of natural positioning with many objectives. The main advantages are:
- Show instantly in search engine results
- Be well positioned on search results that are highly competitive
- Measure and control in real time your advertising costs
- Promote a product, a brand or business
