I decided to throw $50.00 at a little experiment using my new CJ Pay Per Call account and AT&T's Interactive (mobile) pay per call advertising program. I've been looking to use my new account with Ring Revenue (CJ) so I gave it a go and here's how it went: I promoted a cash advance offer that I've done very well with in the past on traditional media buys and used pretty much the same ad that has worked in the past. My bid was $2.00 per call (the minimum) which put me in position 2 for the area of coverage I chose (not bad). For this offer, CJPPC pays $8.00 for calls to my number lasting longer than 1:30 and within my region. The caveat is, AT&T does not allow you to post your own number in the ad, they use their own number (which they do not disclose to you) which is then forwarded to your PPC phone number assigned by CJ. AT&T also charges you your bid price for any call lasting less than 0:12. That's a measly 12 seconds! I also learned that AT&T, being the upstanding company they are (cough, cough), sells the number they assign to your ad to telemarketers that are calling on businesses in the category you chose to advertise in. So if program you are promoting is answered by an automated attendant and it's a telemarketer calling, it will take them longer than 12 seconds to get past the attendant but not long enough for you to get paid before they hang up. The result - you guessed it, you get charged for the call and you don't make any money. Because of the payout to cost ratio, it was pretty much a break even experiment as I did make enough to cover my initial deposit so I believe the method has potential with the right offer and advertsing with a mobile display company other than AT&T. I hope this saves someone else some time and $$$.
