INTERNET Q & A: Brought to you by CNN.COM

Q: What are some different ways advertisers can negotiate an

Interactive campaign?

A: Pay-per-click: In pay-per-click advertising, the advertiser pays a

certain amount for each clickthrough to the advertiser's Web site.

The amount paid per clickthrough is arranged at the time of the

insertion order and varies considerably. Higher pay-per-click rates

recognize that there may be some "no-click" branding value as well as

clickthrough value provided.

Pay-per-lead: In pay-per-lead advertising, the advertiser pays for each

sales lead generated. For example, an advertiser might pay for every

visitor that clicked on a site and then filled out a form.

Pay-per-sale: Pay-per-sale is not customarily used for ad buys. It is,

however, the customary way to pay Web sites that participate in

affiliate programs, such as those of Amazon.com and Beyond.com.

Pay-per-view: Since this is the prevalent type of ad buying arrangement

at larger Web sites, this term tends to be used only when comparing this

most prevalent method with pay-per-click and other methods.
