HI guys i have been promoting pay-per-call for about 1 month and made my first sale $75+ thought i would branch out from only digital conversions. My tip to all who want to try PPC is that to advertise, not only ONLINE but OFFLINE. i have been paying for newspaper ads and its working. Sometime us digital marketers are "drinking our own kool-aid" too much, meaning we are so brainwashed from digital that we forget people still read papers. (even i was skeptical) my conversion is 54 calls = 1 sale (cost me $15 to advertise to make $75+) i know this will fluctuate, just sharing. I wont reveal the niche, or my exact advertising channels, but maybe this will give you some inspiration as other threads on BHW have given me. THANKS!
