In 2020, traditional consumer habits were disrupted and shopping online became the default way to buy. U.S. retailers were swarmed by online consumers, and digital sales for 2020 were boosted by $183 billion, up 42% from 2019. Just a few years ago, it would have been hard to envision a merchant environment where over one-third (34.3%) of retailers sell the majority of their products and services online. In response to this fundamental change in how people buy, businesses across all industries innovated at breakneck speed. They added new web stores, adopted new technologies, and tested new strategies. Most importantly, they learned a lot as they embraced digital selling and discovered what their customers really needed from an online shopping experience. Based on these trends as well as feedback from Magento Commerce customers, we identified seven key lessons that businesses should take away from 2020. We believe that it's imperative for your business act on them now, if you haven't already.
