New to ecommerce? You need all the help you can get to make your website stand out from the crowd. Despite ecommerce representing only 11.9% of all retail sales worldwide in 2017, it is a rapidly growing space, given that its share of retail sales stood at a mere 3.5% only a decade ago. In fact, according to estimates released by Shopify, global retail ecommerce sales are expected to reach a whopping $4.5 trillion in 2021, from $2.3 trillion in 2017. That would be some large pie to try and get a chunk out of. And, in this case, size will matter, right?
