"We offer interstitial and banner advertising. Interstitial ads let you monetize links, even if you don't own the target website. They can also be placed on a web page with an overlay script, allowing you to earn on any visitor simply by having them visit the page. Interstitial ads are billed using a pay per impression system and are better suited for increasing the advertiser's brand awareness. Banner ads fitted for websites bring in users who are genuinely interested in the advertiser's product. They are billed with the popular pay per click system."
