The Pay for Performance or P4P was originally invented by Overture. Overture observed that the internet was growing into a unique kind of shopping mall, where people could shop conveniently and easily and that advertising was gaining grounds on the internet. But now, Overture has been taken over by Yahoo and hence popularly known as Yahoo.
A visible and popular website attracts more and more people. It provides ads in other sites that link to a particular site can direct potential consumers and customers to that site thus increasing traffic and sales in that website. Yahoo provides a service using which it is possible to show ads kept in their websites when people input certain keywords.
Using Yahoo services, any willing website can have their traffic increased by utilizing the same. When more and more people become aware of your site, the traffic to your website would automatically increase. This in turn would increase the chance of people viewing your pages and products. Even if a small fraction of those people actually buy your products; that would still mean a substantial figure for you and your company.
It is the goal of every internet based company to get a high volume of potential consumers to their website. To accomplish this, the companies try a handful of methods to make their website more and more popular and make the people all over know about the existence of their services.
