Terminology. Lesson One

Terminology... I know, it's boring. But by the end of these lessons, you will be a banner ad expert!

* Clicks/Click-throughs: The number of visitors who click on the banner ad linking to the advertiser's Web site. Publisher sites often sell banner ad space on a cost-per-click (CPC) basis.

* Page views: Also called page impressions, this is the number of times a particular Web page has been requested from the server. Advertisers are interested in page views because they indicate the number of visitors who could have seen the banner ad. Although they don't measure the effectiveness of a branding campaign, they do measure how many visitors were exposed to it. The most common way to sell banner ad space is cost per thousand impressions, or CPM (In roman numerals, M equals a thousand).

* Click-through rate (CTR): This describes the ratio of page views to clicks. It is expressed as the percentage of total visitors to a particular page who actually clicked on the banner ad. The typical click-through-rate is something under 1 percent, and click-through rates significantly higher than that are very rare.

* Cost per sale: This is the measure of how much advertising money is spent on making one sale. Advertisers use different means to calculate this, depending on the ad and the product or service. Many advertisers keep track of visitor activity using Internet cookies. This technology allows the site to combine shopping history with information about how the visitor originally came to the site.
