Zango provides wallpapers, screensavers, games, videos etc for free download by your site visitors. Zango offers an incentive to you, the webmaster whenever an user downloads a wallpaper, screensaver, video etc. Zango displays ads to your visitors when they use the downloaded products. You receive a percentage of this income. Coming back to the actual content, Zango offers complete integration of the content with the look and feel of your site. New content is added regularly. The only downside would be the same content is already available on hundreds of sites - so you will need to integrate with your own content to make it more useful and unique. Also keep a tab on the pulse of your visitors to see how comfortable they are with the installation requirements. Zango pays $0.40 per install - that is what they advertise. But that is only if the installation happens in US. For other countries the rates are different and much lower. Even installaions in UK pay only $0.19 and most asian countries will earn you a measly 1c per install. Take a call. Zango gives you good content but if you are looking at it as a source of income then you need a high percentage of traffic from the US.
