There is too much of theoretical marketing content out there. Marketing is not a theory, it is an implementation, and spending times on these webinars where people that do not know how to do do things, are preaching people with even less of a clue on the theory of the practical things that may or may not know.
Most of this theoretical content is more harmful than productive for business owners and marketing managers alike.
People keep looking outside of themselves for solutions, but the real answer is in practice, and knowing where to look at.
Do your own thinking.
