Key Takeaways
- Retail giant Amazon draws more than double the web traffic as Walmart, its largest competitor.
- Commanding about 40% of the U.S. ecommerce market, Amazon’s dominance in app users is even greater—outpacing the next four biggest competitors combined.
- China-based Temu now ranks as the third-most popular ecommerce app in America, with its market share projected to triple to 2.3% in 2025.
U.S. ecommerce retailers generated $300.2 billion in sales in the first quarter of 2025—accounting for 16.2% of the total.
Not only do Amazon and Walmart drive the majority of sales, unsurprisingly, they drive the majority of traffic and app users. However, a number of platforms including Etsy and eBay attract millions of visitors thanks to their distinct business models.
This graphic shows the most visited sites and apps for ecommerce retailers, based on data from Similarweb.
Amazon Dominates Traffic Across eCommerce Retailers
Between October and December 2024, Amazon brought in an average of 390 million monthly active users to its site, surpassing Walmart’s 166 million.
Meanwhile, online platform eBay ranked in third, attracting 106 million visitors. Today, eBay along with Etsy, are investing in algorithm-based personalization tools that mirror TikTok to drive sales.
| Rank | Domain | Monthly Unique Visitors |
|---|---|---|
| 1 | amazon.com | 390M |
| 2 | walmart.com | 166M |
| 3 | ebay.com | 106M |
| 4 | target.com | 96M |
| 5 | etsy.com | 86M |
When it comes to app users, Amazon dominates once again—but Temu is quickly catching up. With 89 million active users, it stood as the most downloaded app in the country in 2024.
As the table below shows, Amazon saw 255 million monthly active users between October and December while Temu witnessed 69 million.
| Rank | App | Monthly Active Users |
|---|---|---|
| 1 | Amazon | 255M |
| 2 | Walmart | 96M |
| 3 | Temu | 69M |
| 4 | Target | 39M |
| 5 | eBay | 35M |
In many ways, legacy U.S. retailers attract the highest number of users thanks to their broad consumer base.
On the other hand, Temu’s expansion into the U.S. market is on shaky ground. Following sweeping tariff announcements in April, Temu’s U.S. daily users plummeted 48% between March and May.
