After 20 years in advertising, I recognize “cost-per-action” is the internet version of “cost per enquiry” in print and broadcast media. Instead of paying a fixed rate for an advertisement, the advertiser agrees to pay a certain amount for each coupon returned from a newspaper or magazine ad, or phone call in response to a TV or radio ad. Since the advertiser does not need to make a large advance investment and the medium shares the business risk, this model has largely been used for marginal merchandise, like kitchen gadgets and self-help programs, advertised in otherwise undesirable places, like late night television or the back pages of comic books. If an ad is successful, the medium may choose to run it over and over again, as any viewer of late-night TV — or visitor to many web sites — can attest!
