Is there any factors to fix the cost for PPC advertisement?

Pay per click is an Internet advertising model used to direct traffic to websites, where advertisers pay the publisher when the ad is clicked. With search engines, advertisers typically bid on keyword phrases relevant to their target market. Content sites commonly charge a fixed price per click rather than use a bidding system. PPC "display" advertisements are shown on web sites or search engine results with related content that have agreed to show ads. This approach differs from the "pay per impression" methods used in television and newspaper advertising.
