In contrast to the generalized portal, which seeks to drive a high volume of traffic to one site, PPC implements so called affiliate model, that provides purchase opportunities wherever people may be surfing. It does this by offering financial incentives to affiliated partner sites. The affiliates provide purchase-point click-through to the merchant. It is a pay-for-performance model—if an affiliate does not generate sales, it represents no cost to the merchant. The affiliate model is inherently well-suited to the web, which explains its popularity. Variations include, banner exchange, pay-per-click, and revenue sharing programs.
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.
