You Could Try To Do It All By Yourself (Which Is VERY Hard). Or Maybe..YOU COULD OUTSOURCE EVERYTHINGThe answer is because there's ONE FATAL FLAW with affiliate marketing. No one wants to tell you this secret, but I will. The problem is that it takes the average person seeing an offer SEVERAL times before they're likely to purchase. The truth is that 99.5% of people who see a product you're trying to sell, WON'T buy it the first time they see it. Therefore, if you don't have a way to automatically follow-up with people (while you sleep), then your chances of making sales is pretty much zero. |
