Pay-per-click advertising is often referred to as performance-based advertising. In other words, you pay for results and not for exposure. To put this in context, think of tradicional newspaper classifield ads where you are usually charged per word to run your ad. Similarly, you may have come across some web sites that will let you run a banner advertisement for a specified amout of time when you pay upfront. The problem with that form of advertising is that you have no guarentee of results. You could spend hundreds on pay-upfront advertisements and end up going broke if your ad performs poorly no one responds, no one clicks on your link, etc.
The PPC model of advertising, however, gives advertising like you the advantage by letting you control costs. Instead of being charged for publication or ad exposure, your ads are run for free. You do not actually pay anything until someone clicks on the link to your web site - hence the "pay-per-click".
