Now let us take a look at the interesting part of a proxy project - making money! To start earning dollars you have to publish adverts on your page.
Context-oriented ads
I recommend to publish Google AdSense adverts on the main page of your proxy site. With Google AdSense you are able to serve ads based on the website content, so users will often click an advert because they are really interested in it. Sometimes you earn up to 2$ per click with proxy related keywords. You have to position the adverts nearby the surfbar which the visitor depends on to surf with your web proxy.
Layer Ads
Another consideration you can think about is to display layer ads on your website. The advantage of layer ads are that they are paid per view by the most advertising networks. The disadvantage is that your are annoying your visitors and sometimes scare them away from your site. Also you can not show this type of adverts on your main page because it would conflict with Google AdSense guidelines. So you have to show those ads not till then the visitor starts surfing his sites with your web proxy. You can do so if you copy the code snippet you got from your layer advertising platform just before the html code in the
index.php file.
advertising networks
The best provider for converting international traffic into money is definitively
PopupTraffic, they pay you up to $1.80 per 1.000 visitors and they even pay for non uniques and all countries. The best provider for converting traffic from Germany, Switzerland or Austria is
Layer Ads. They pay you up to 7 EUR ($10) per 1.000 impressions. If you know better providers, please let me know it.
Geo-targeted ads
To efficiently capitalize your incoming traffic, you should locate what country your visitor is surfing from to display ads of the advertising network which has the highest payout rates for traffic of the particular country. You can do so by
implementing a geo-locating database to associate IP-Ranges with countries.
