What is the best way to start and set up a marketing funnel?

“Marketing Funnel” is a long-standing phrase that explains the progression a lead takes to becoming a customer. 

 A traditional marketing funnel looks something like this:

People can jump into your marketing funnel from a practically unlimited number of sources and stay in touch with you for an undefined period of time… or until they opt out.  This gives you opportunities to:

• Build a community of followers
• Establish rapport
• Communicate about the current book and future books
• Promote sales
• Establish a list that you control
• Improve your social standing
• Increase search engine rankings

I agree with Mr. Nasir answer. Thank you
