The top 15 sneak peek might have curbed curiosity temporarily, but if you’re anything like us, we want to know “why” these companies are on top. Using Similarweb Sales Intelligence tells us precisely that.

Let’s see it in action with a deep dive into the top 5 ecommerce companies in the US in December 2025:

1. Amazon.com

New ecommerce competitors emerge on the scene every day, but with 2.714B total visits and month-over-month (MoM) visits up 8.14%, Amazon continues to lead the category.

Amazon.com’s largest traffic source was direct search, with 1.7B visits, followed by organic search, with 545.9M visits, and paid with 158.5M visits.

When looking at engagement metrics, we see that bounce rates have improved by 0.2% on desktop and 0.39% on mobile.

As mentioned, Direct and Organic Search led the charge in driving traffic to Amazon. So, what was the world looking for that led them to the site? Short answer: Prime and Kindle, plus a big dose of shopping and gift-hunting. Slightly longer answer: these are the 15 most popular organic non-branded keywords for December…

Prime- and Kindle-related search terms made up nearly half of the top 15, with Prime Video alone pulling in 1.8M clicks. Outside of Amazon-owned products, we see shoppers searching for specific brands and items like AirPods Pro 3, Crocs, Lululemon, and Uggs, plus seasonal intent starting to surface through “white elephant gift ideas.” Most of the top 15 keywords saw positive MoM change, and “white elephant gift ideas” was the breakout with a +1,709% MoM increase.

When looking into the engagement metrics, we notice an uptick in December for Pages Per Visit on desktop (0.37%) and mobile web (0.19%).

Jumping over to the channels that drove the most traffic, direct search brought in the most (373.7M), followed by organic search (141M), and then social (29.4M). These three channels respectively contributed 61.58%, 25.70%, and 5.35% to the total traffic.

What were people really searching for on eBay? The short answer: the unexpected. Curious shoppers turned to eBay with some truly unique queries. To give you a glimpse into the minds of eBay users, here are the platform’s 15 most popular non-branded organic search terms from December.
