What do you mean by
"Front End"?

Think Website, Landing and Sales Pages, Lead Magnets....any type of page that is out there being advertised or displayed by you on the web. From simple web pages to Webinar Optins and Free PDF Downloads.

Google can find you.
Facebook can find you...
And most importantly your prospective customers and tribe can find you. 

This is your Front End. 
This is the face you present to the world and a very big part of your selling arsenal.
