Twenty years ago, we didn't have e-commerce, email, paid search, search engine optimization, affiliates, referrals, shopping comparison sites, landing pages, shopping cart abandonment programs, in-app messaging, text messaging, Facebook, Twitter, Pinterest, Instagram, Tumblr, blogs, user reviews, the iPhone, Android, tablets, podcasts, Cyber Monday, smart televisions, and countless other selling tactics or channels. We didn't know what multi-channel was, and we certainly couldn't anticipate what has been labeled "omnichannel" - the integration of a retail business with online channels. So with all of the selling opportunities outlined above, why aren't most retail and catalog businesses experiencing unfettered growth? And why are so many e-commerce businesses beginning to tap out on growth opportunities? In "Hillstrom's Diagostics", Kevin Hillstrom explains the diagnostics he uses to identify why a business is not growing. The methodologies are simple, easily implemented by any analyst with programming skills. The methodologies quickly pinpoint the problems within the customer file, and diagnose the merchandising challenges that hold a business back. The booklet does not tell you how to fix the problems, that's your responsibility as a business leader. But the booklet clearly articulates how to identify your specific problem.
