Why is Online eCommerce so important?

Online spending represented 21.3% of total retail sales for the year, according to Digital Commerce 360 estimates. Amazon accounted for nearly a third of all ecommerce in the United States.
Consumers spent $861.12 billion online with U.S. merchants in 2020, up an incredible 44.0% year over year, according to Digital Commerce 360 estimates. That’s the highest annual U.S. ecommerce growth in at least two decades. It’s also nearly triple the 15.1% jump in 2019.

Online’s share of total retail sales has steadily been on the rise—with ecommerce penetration hitting 21.3% in 2020, Digital Commerce 360 estimates. That’s up from 15.8% in 2019 and 14.3% in 2018. The more than five-percentage point gain in ecommerce penetration is by far the biggest year-over-year jump for U.S. retail sales ever recorded. No other year has even reached a two percentage-point gain in digital penetration.
