Practical Ecommerce's Ignite 2015 conference contains 39 sessions on topics critical to small and midsize ecommerce merchants, to accelerate revenue growth and compete against larger companies.In addition, we'll feature two visionary keynote speakers. The first one, on opening day, is John Lawson. He's an ecommerce entrepreneur and a social-selling guru. His address, "The Beyonce Principal: Social Selling Funnel for Massive Results," will emphatically answer the question of how smaller ecommerce merchants can harness social media.
