Advertisers, like Google AdSense or Overture, only pay ad publishers when readers actually click on ads published on their sites.

Pay-per-click advertisements are usually displayed with the highest paying bidder in the top or most prominent position.

Navigating the complex web of Internet marketing, publishers and marketers are often confronted with terms that seem foreign.

This simple micro-guide will give basic assistance to online marketers in navigating the Pay-Per-Click marketing model with a better understanding of these industry-specific terms.

Conversion Rate - The relationship between visitors to a web site and actions considered to be a "conversion", such as a sale or request to receive more information: the percentage of people whose clicks have resulted in a sale or desired action in relation to the total number of clicks on an advertisement.
