How to leverage public speaking to market your business

Think about Gary Vaynerchuk and his marketing strategy - lots of content, most of it in video with many speeches delivered at events around the world. Or a closer example - Paweł Tkaczyk or Michał Sadowski. Speaking at conferences is a vital part of their businesses. Very few people consider public speaking a marketing tool, yet it's a powerful one. It's actually a part of content marketing in which you have a chance of presenting yourself as an expert to a group of specific people (target!) who want to listen. What a great opportunity! But how to leverage it? I want to tell participants exactly that - tips&tricks, case studies, knowledge based on practice - 100% mięso.
