A lot of businesses today are using pay per click ads to get noticed. What makes PPC so popular? Like many business decisions, the bottom line is the bottom line. Advertising can get expensive, and with ppc ads you only pay for users who are interested enough to click through.
A great aspect of pay per click is that you can guarantee you stick to your budget. Most will remove your ad from rotation when you reach a budget maximum. When your advertising budget is tight, it is important to make sure every dollar spent is actually reaching a potential customer.
