There are 7.9 billion people in the world as of 2021.

And out of these 7.9 billion people, over 2.14 billion people are expected to buy goods and services online.

2.14 billion / 7.9 billion = 27%

One in every four people are now shopping online and this number continues to grow!

In first world countries like the United States, ecommerce is even more prevalent. Right now, the population of the US is 333 million and there are 230 million US online shoppers.

230 million / 333 million = 69%

Two out of every three people in the US shops online!

With this many online shoppers, there has never been a better time to start an online store

Ecommerce Statistic #2: Ecommerce Will Account For 19.5% Of Retail Sales In 2021

Ecommerce Sales

According to Statista, ecommerce sales will make up 19.5% of all retail sales in the world in 2021.

Ecommerce was never supposed to grow this quickly. If you look at the graph above, ecommerce jumped from 13.6% to 18% in 2020 alone due to the pandemic and it’s expected to grow exponentially in the coming years.

In the US, ecommerce grew even faster at over 40% in 2020.

Even though 19.5% of sales is an impressive number, there’s still much room to grow. If the current trend continues, ecommerce sales will exceed 22% by 2024. Looking further out to 2040, ecommerce sales are expected to reach 95%.

The continued growth of ecommerce represents a massive opportunity for small business owners selling their own products online.

Below are the ecommerce growth numbers for 2020.

  • Amazon’s net profit increased by over 80%.
  • eBay’s net revenue exceeded $10 billion.
  • Shopify’s revenue grew over 85%.

Ecommerce Statistic #3: 37% Of Small Businesses Don’t Have A Website

A common question that I’m often asked is whether ecommerce is saturated. And the answer is not even close!

According to a survey conducted by Visual Objects, 37% of small businesses in the US don’t even have a website.

Furthermore, almost 25% of the surveyed businesses struggle with the time and expertise required to build and maintain their websites.

For many small businesses, their website is not a priority and 77% of in house employees balance running their website along with other responsibilities.

Thanks to fully hosted ecommerce platforms like Shopify, BigCommerce and Shift4Shop, starting your own online store website is easier than ever.

Ecommerce Statistic #4: 55% Of Small Businesses Don’t Have A Documented Conversion Optimization Strategy

According to CXL, 55% of small businesses surveyed don’t have a documented conversion rate optimization (CRO) strategy.

Furthermore, about 33% of website optimizers have no process in place for user research or testing.

In other words, many small businesses don’t understand how to create a high converting website. In fact, 34% of businesses stated that they use their website primarily to showcase their products and services.

If you are willing to study conversion optimization, there’s a huge opportunity for you to create a much better website than your competitors.

Many small businesses don’t know what they are doing.

Ecommerce Statistic #5: 75% of Repeat Purchases Are Made Online

According to Statista, nearly three quarters of repeat purchases are made online.

The main reason is because there are many more ways to reach your customer online than offline.

For example, you can run automated email marketing sequences to retain your customers such as…

  • Post Purchase Cross Sell Campaigns
  • Customer Winback Campaigns
  • Anniversary Or Replenishment Campaigns

You can also use SMS marketing to send text messages to your customers about new products and promotions.

Facebook Messenger Marketing is also a great way to reach your customers through Messenger and Instagram DMs. In fact, you can run a customer loyalty program for free via Messenger alone.

Finally, there are a variety of ways to run Facebook retargeting ads to retain customers as well.

Bottom line, the possibilities for customer retention are limitless for an ecommerce store versus a brick and mortar store.

Ecommerce Statistic #6: People Shop Online Because They Can Shop 24/7

We live in an “on-demand” world. Think about it. When was the last time you watched broadcast television outside of the morning news or live sporting events? Services like Hulu, Netflix and Amazon allow you watch shows and movies whenever you want.

The same is true with online shopping.

Consumers want to shop when they want to shop no matter the time of day. Thanks to the pandemic, Forbes found that 59% of surveyed correspondents preferred to shop online during the busiest time of year.

Bottom line, consumers prefer to shop online and thanks to the pandemic, this will likely never change.

Ecommerce Statistic #7: 35% Of Shoppers Price Compare On Mobile While Shopping At A Brick And Mortar Store

Because ecommerce stores don’t have to pay rent to maintain a physical store, the overhead is much lower.

For example, we started our online store for only $630 and ran it out of our house for the first few years. Back then, our monthly expenses were less than $30/month.

Because there is far less overhead for an online store, you can offer lower prices for customers and the upfront risk is far less.

Today, over a third of customers comparison shop on their mobile phones while shopping at a physical store. And these shoppers often find lower prices online.

This practice is called showrooming. Consumers will shop at a physical store to touch and feel the product before making their final purchase online.

By running Google Shopping Ads, you can make your products appear at the top of the search results so you can steal business from your brick and mortar competitors!

Ecommerce Statistic #8: 43% Of Consumers Conduct Online Research While Shopping At A Physical Store

One of the main reasons people prefer to shop online is because you can thoroughly research the product you want to buy.

Most and brick and mortar stores offer very little documentation and stores are often sparsely staffed to save money on headcount.

As a result, 43% of consumers conduct research on their mobile phones while shopping at a physical store.

If you can create detailed research and product comparisons on your website (along with competitive prices), then you have a good chance of stealing a sale from a brick and mortar store.

Ecommerce stores benefit from the ability to create high quality product descriptions that you can’t find at a physical store.

Overall, here are the statistics for smartphone usage in a physical store.

  • 46.8% consumers look for discounts
  • 43.3% look up product information
  • 35% compare prices
  • 27.6% look up product reviews

Ecommerce Statistic #9: 86% Of Millennials In The US Shop Online

Millennials alone have a penetration rate of 86.2% for online shopping.

Below is the distribution for digital buyers in the US in 2020 according to Statista.

Digital buyer distribution

Millennials aged 25 to 34 years represent the largest group of online shoppers in the US followed closely by Gen Xers aged 35-44 at 17.2%. Surprisingly, people over the age of 45 make up an exceptionally large percentage as well.

Bottom line, every age group is shopping online today. Ecommerce is mainstream.

Ecommerce Statistic #10: It’s Extremely Inexpensive To Start An Ecommerce Store

Depending on the ecommerce business model you choose to pursue, the cost to start an online store will vary. However, compared to a brick and mortar store, starting an online store will easily cost you 100x less.

Below is a table of how much it costs to start an ecommerce business based on your business model.

  • Dropshipping – Based on data from students in my ecommerce course (~4000 students), you should expect to pay between $3 and $500 on average to start a dropshipped online store.
