Hello! We are selling software and as one of our products is quite innovative it's better to explain its characteristics personally or on the phone rather just sending people to a landing page. So I thought that it would be great to participate in something like adwords, but where you would pay per call rather than per click. Which is the most popular pay-per-call program with the widest range of audience? It would be great if somebody would help me with this
This would be great if I could find a good solution for this. Perfect for service companies and whatnot.
