I have worked in marketing for almost 20 years. The "most effective and profitable" marketing methods will, for the most part, vary per company. Despite the influx of free seminars and workshops about how to dominate with internet or social media marketing, the truth is, unless your business is self-promotion, then you need to dig deeper.
I would suggest that the question, especially when addressing smaller businesses and start-ups, is actually the wrong question. We really need to take a step back.
