What is the difference between the PPC program and banner ads?
In the case of banner ads, you pay based on the number of times they are displayed regardless of the number of visitors who “click” on them, and in some cases you pay for actual clicks. By and large, banner ads are ineffective at getting visitors to your web site because, in most cases, the ads displayed aren’t relevant to what visitors are looking for. On the other hand, pay-per-click marketing is highly effective because visitors only see the listings that are highly relevant to what they are searching for.
