Yesterday I got a visit from the Yellowbook people. I canceled all my "Yellow Pages" advertising a couple years ago because I just wasn't getting enough leads from it to justify the expense. Apparently they've heard our frustration, because they now have a "Pay Per Call" arrangement. They set you up with a separate phone number which forwards to your regular phone, and that is the number they publish. You only pay when someone calls through that number. They filter out solicitation calls, short calls (e.g. wrong numbers), and repeat calls so for the most part you only pay for legitimate inquiry calls. The cost per call varies by type of business and area, but it's on the order of several dollars. I've been telling ad sales reps for years that I only want to pay for actual performance, not vague promises of more business... and it looks like they've finally heard me Has anybody else used a service like this? How does it shake out in the real world?
