Pay-Per-Call gained even more momentum last week when AOL announced that they'll soon offer advertisers this service. An article by Michael Bazeley in the SJ Merc takes a look: AOL to try Ingenio's technology.
Though the pay-per-call concept is new, Ingenio is not. Founded in 1999 as Keen.com, the 90-person company developed technology that allows it to track and bill for phone call usage. Its first use of the technology was for an e-commerce Web site that allowed Web users to find professionals willing to offer phone advice in areas such as tax preparation and computer technical support.
