This is how you really make the low ticket front end offer work.
Remember that it is just that a front end offer. You wont make any money selling $7 offers unless you are getting millions of visitors for free somehow.
The front end offer is designed to separate the buyers from the looky-loos, and to begin the trust building process, and maybe even break even on your advertising costs.
You don't stop there though.
The process doesn't work unless you have the rest of the funnel built out (which you can build as you go)
You need to have additional offers at various price ranges going all the way up from $37 all the way to $3,500 or more
The classic business advice is just as true in the internet era. Make the first sale which will be the hardest even at $7 or $2.99 or whatever
Then focus on the repeat business reselling your clients or customers on your upsells (repeat business)
It's way easier to resell a current customer than it is to find a new one. New customer acquisition is the real challenge, even if you give away your front end offer for a penny, becasue they just don't trust you.
You want to have a system in place that will move your low end clients up the scale and not place all your focus on selling a $7 report you'll never make any profit on.
make sure you are looking at the big picture
