Top Ecommerce Companies in the USA: The 100 Brands Winning the Traffic Race in 2026

2025 brought no shortage of change. Markets shifted quickly, competition intensified, and uncertainty became the backdrop. The challenge in moments like these is knowing what matters, where to focus, and how quickly to act.
That’s why in 2025, we focused on removing friction from the most important jobs you need to accomplish.
From controlling brand visibility in AI-driven discovery to analyzing markets at scale, benchmarking more intelligently, spotting trends earlier, and turning insights into always-on intelligence, every update we shipped last year was designed to help teams move faster, from question to answer and from insight to action.
In this post, we’ll look at those updates through the lens of the real work your teams do and how Similarweb helps to make that work simpler, smarter, and more scalable.
2025 was a defining year for Gen AI. Multiple steps in user journeys collapsed into a single conversation, and brands realized that showing up in AI-driven discovery is no longer optional. Missing this moment means handing an entire channel to competitors.
In response, we launched Gen-AI Intelligence and improved our Gen AI Brand Visibility Tracker to give teams more control, including topic-level tracking and sentiment, plus broader LLM coverage and localized AI responses. You now have a clear view of how your brand appears across AI-driven discovery and where to focus next.

Staying on top of competitors and markets has traditionally required constant effort. In response, we focused on eliminating the manual work that slows teams down. What once meant repeated searches, tool-hopping, and drained resources is now a more seamless experience.
By removing friction at key points in the workflow, we made it easier to stay informed without constant effort. Insights surface faster, important updates arrive automatically, and less time is spent navigating the platform, so teams can focus on acting, not searching.

As AI becomes part of everyday work, the limiting factor isn’t access to tools. It’s trust in the answers they produce. Too often, teams are forced to choose between speed and reliability, relying on AI that moves fast but isn’t grounded in real market data.

In 2025, we took a major step toward closing that gap with the launch of our MCP server. MCP makes it possible to connect Similarweb data directly to AI tools like Claude, Cursor, and custom AI agents, allowing you to ask competitive and market questions in natural language and get answers powered by live, trusted intelligence.
Instead of exporting data, stitching together analyses, or second-guessing AI outputs, you can now access Similarweb insights where they already work. What once took hours of manual effort can now happen in minutes, inside an AI conversation, turning AI from a speculative assistant into a reliable partner for analysis, reporting, and data-driven decision-making.
Connecting trusted market data to AI tools is a critical step. But even with better answers, many teams still spend time repeating the same analyses, preparing the same briefs, and manually translating insights into next steps.
That’s where automation needs to move beyond answering questions and start doing the work.
In 2025, we introduced Similarweb AI Agents to help teams move from insight to execution more quickly and consistently. These agents aren’t general-purpose assistants. They’re specialized AI teammates, each designed to handle a specific, high-impact job that teams perform every day.
Built on Similarweb’s proprietary digital data and embedded directly into existing workflows, AI Agents turn analysis into an ongoing system rather than a one-off task. They monitor signals, interpret change, and deliver clear, actionable outputs without requiring manual setup, prompting, or repeated effort.

The first generation of Similarweb AI Agents focuses on some of the most critical jobs across marketing, strategy, and sales:
Together, these agents represent a shift in how digital intelligence is applied. Instead of pulling data, interpreting it, and deciding what to do next, teams can delegate recurring analysis and preparation, freeing time and attention for judgment, strategy, and action.
Paired with MCP, AI Agents complete the loop, giving you trusted data flows into AI, and AI turns that data into work that actually gets done. It’s a more scalable, reliable way to operate in fast-moving markets and a foundation for how digital intelligence will evolve next.
Benchmarking only works when comparisons are relevant. In 2025, we focused on increasing precision without adding complexity.
By enabling benchmarking at the business-line level and improving the clarity and accuracy of channel data, we made it easier to compare performance against the right competitors and the right metrics. The result is simpler benchmarking, clearer context, and faster, more confident decisions.

Our Market analysis tool now spans multiple industry views, making it possible to compare industries and understand how markets relate to each other. At the same time, our predefined industries now reflect how markets evolve, including the emergence of entirely new categories like AI.

We made our demand analysis tool more forward-looking by adding AI-driven context to demand changes, expanding discovery beyond predefined keywords, and introducing more current, continuously updating views.
This makes it easier to understand what’s driving demand as it unfolds, giving teams earlier visibility, clearer explanations, and more time to act before shifts appear in downstream KPIs.

In paid media, the challenge is knowing where value is being created and where it’s leaking away. You need clarity on who’s advertising where, how competitors are bidding, and when brand spend is being wasted without manually monitoring campaigns around the clock.
We expanded our Ad Intelligence capabilities to help teams protect performance and uncover opportunity, turning competitive ad activity into actionable insight.

Understanding competitor SEO strategies shouldn’t require manually sorting thousands of keywords or guessing which content themes actually drive visibility. As keyword lists grow, it becomes harder to see the bigger picture and even harder to turn that data into a clear content plan.

With Keyword Clusters in our Keyword Research suite, your SEO team can instantly see the content themes driving traffic for any site. Related queries are automatically grouped into meaningful topics, making it easy to understand what competitors are ranking for, which themes they’re investing in, and where gaps exist.
Just as importantly, these topic groupings provide a ready-made foundation for your own strategy. Instead of starting from a blank slate, SEOs can use competitor topics to define their own content themes, prioritize opportunities, and build content plans faster without the manual work of keyword categorization.
Whether it’s AI visibility, smarter benchmarking, market analysis at scale, or early trend detection, the common thread in 2025 was the same. Helping you move from analysis to action faster and with less friction.
Across every update, the goal was to reduce manual work, surface what matters sooner, and make digital intelligence something teams can rely on continuously, not something they have to chase. By focusing on the real jobs teams are trying to get done, we built tools that fit naturally into how decisions are made today and how they’ll be made tomorrow.
As markets evolve and discovery continues to change, that focus remains the same. Helping teams see clearly, move confidently, and stay ahead.
