Adsense CTC or click-to-call is a beta system released by Google. It is a system actually being used in select portions of the US. What it basically does is to provide real-time phone conversation between Adsense clients and their subscribers.
Several programs similar to Adsense CTC's are available from other web-based companies as well. However, with Adsense CTC's program, the specific target is advertising. Adsense CTC then can actually be likened to a telemarketing program in that clients are charged after a phone call has ended. They are likewise similar to CPC-based advertising programs because client payments will only be made after pre-determined conditions have been met.
One good thing about Adsense CTC is that it does not utilize a traceable toll number. What it does is that it acts as an outsourcing provider. The Google website has actually set up its own hub to handle calls. The result is a faster processing of the telephone call entries.
In addition, Adsense CTC users need not be concerned that their personal history might be released to Adsense clients. Such things will happen only when the clients themselves ask for personal facts and data while talking to the subscribers.
Google is bent on maintaining the privacy of their subscribers in its CTC service. It promises not to disclose any personal subscriber data to any external party. Even during actual phone calls, the subscriber's phone number is kept hidden. As an added measure, the phone numbers get omitted automatically from the CTC system after a brief interval.
