How to Build a Business That's Not Dependent on One Marketing Channel

How do we find a way to build a business that isn't overly dependent on one customer acquisition method? Will we have to diversify? Is 95 % of your sales derived from paper click advertising? What will you do when that click cost goes up from two 50 to five dollars, and your margin's gone? That would keep me up at night. So i'm suggesting you don't double down and take advantage of your certain marketing channels when they're working. Just be mindful of the risks of dependency and be ready to shift gears when it changes.
