What Is The Best Starting Strategy For Generating Leads?

During episode 80 of our weekly Hump Day Hangouts, one participant asked about the best starting strategy for generating leads.

The exact question was:

if you were starting a new campaign for generating leads for a new client (lets say in something like home remodeling), what would be your starting strategy in a nutshell (ex. build a 2-tiered network around a lead gen website + branded youtube channel), also do you have a product that best covers lead gen fulfullment (+ sales)??
