Pay per Play Advertising
There are many ways to earn money from hosting a website. As seen on this one, it's littered with Google Ads (Adsense), and every click is generating revenue for the individual or company hosting these ads. The statistics can be broken down into 2 main parts. First you have your "page impressions" (number of times the page holding the ads is viewed), and secondly the number of clicks on the ads. Together they form a ratio known as the "click thru rate", which tells you what percentage of people who come to your website actually click on your Google Ads. Usually, the click thru rate is somewhere between 0.01 and 2 percent, any higher and Google starts getting suspicious. What that ratio is telling you is that you are earning revenue from 0.01 to 2 percent of the people that visit your website.
However, imagine if you could have a 100% click thru rate. Or even better, there is no "click" required, you just earn money from every page impression.
Pay per Play is an advertising program that plays a short 5 second audio clip advertisement to every visitor to your website. As the name tells you, they pay per play. That means that every visitor to your website is generating revenue for you. Another advantage of this over Google Ads is that none of the visitors to your site are directed away.
Ofcourse you have to place these ads wisely. If a page in your website get reloaded quite often, it can get very annoying to the visitors of your website. I also don't advise anybody to apply these ads to your general home page or landing page.
If you're already in to Google Adsense, that's fine too, because you can run both advertising programs.
The Pay per Play program is starting in February 2008, so during this time you can get ahead and join the referral program and earn more money on top of what you earn from your own website.
