2019 was a blockbuster year for online retail. Consumers spent $9.4 billion on Cyber Monday alone, a whopping 19 percent increase over 2018.

With 26 percent of consumers shopping online every week, according to Episerver’s 4th Annual Reimagining Commerce Report, it shouldn’t be a surprise retailers put up big numbers in 2019.

The broader retail landscape was mixed, however, with the Commerce Department reporting several months of negative sales growth in 2019.

In 2020, retailers should take credit for delivering strong ecommerce sales while taking note of broader economic trends that may make earning consumer dollars more difficult in the future.
