Different jurisdictions have taken different approaches to privacy issues with advertising. The United States has specific restrictions on online tracking of children in the Children's Online Privacy Protection Act (COPPA),:16–17 and the FTC has recently expanded its interpretation of COPPA to include requiring ad networks to obtain parental consent before knowingly tracking kids. Otherwise, the U.S. Federal Trade Commission frequently supports industry self-regulation, although increasingly it has been undertaking enforcement actions related to online privacy and security. The FTC has also been pushing for industry consensus about possible Do Not Track legislation.
CPA (Cost Per Action or Cost Per Acquisition) or PPP (Pay Per Performance) advertising means the advertiser pays for the number of users who perform a desired activity, such as completing a purchase or filling out a registration form. Performance-based compensation can also incorporate revenue sharing, where publishers earn a percentage of the advertiser's profits made as a result of the ad. Performance-based compensation shifts the risk of failed advertising onto publishers.:4, 16
In sales, we all know that customers generally need to hear about the product. They need to see the product. They need to do both multiple times before they decide to buy. Often they will use your affiliate link to go to the product, and then later just google the product to return to it. Sometimes the customer knows he is being sold. He wants to get around you and directly to the product. In most cases, you caused the sale but you can’t earn on the sale. Not so with ClickFunnels.
