The Impact of COVID-19 on E-commerce sales

(Source: Statista, UNCTAD)

COVID-19 continues to affect e-commerce sales, alongside online consumer behavior. Since thousands of people were said to stay at home, to slow down the spread of the virus, online shopping became the best alternative for the in-person shopping experience.

It comes as no surprise that in June 2020, e-commerce traffic registered 22 bn visits each month. Simultaneously, the demand for groceries, clothes, hygiene, and tech items made some of the best covid sales. Therefore, Latin America, Africa, and China marked a significant rise in online retail sales.

For instance, Latin America was selling x2 much more than the previous year. The African platform, Jumia, has seen fifty percent more transactions in the first 6 months of 2020.

On the other hand, less developed countries and places, weren’t so lucky to capitalize during the pandemic; mostly due to constant blockades like

  • Poor to none IT skills
  • Distrust among consumers
  • Overpriced broadband services
  • Lack of governmental integration in the eCommerce, etc.

Depending on how COVID-19 continues to change the world, online usage and e-commerce sales will also be changing.


It is easy to summarize the above-mentioned stats and facts on eCommerce sites. It is more than obvious that e-commerce is creeping into every aspect of the global economy. Moreover, it is spreading with a skyrocketing speed around the globe.

The advances that mobile technology is achieving by the year, are paving a smooth path to e-commerce in all directions. As well as the fact that more and more people are online, whether that be through a desktop or a mobile device. Additionally, the COVID-19 gave quite the push (upwards) to this contagious business sector, thus, it looks like there is no way but UP for eCommerce.
