Similarweb estimates how much traffic any website or app gets, where that traffic comes from and how it compares with competitors. Marketers use it to benchmark their site, research a market and see which channels, keywords and ads work for rivals.
Who is Similarweb for?
Similarweb suits marketers, SEO and PPC teams, market researchers and agencies that need data on sites they do not own. Analytics tools such as Google Analytics only measure your own site. Similarweb fills that gap with estimates for everyone else. Large companies buy custom packages with longer history, APIs and data feeds.
What are Similarweb's main features?
Website and competitor analysis
Enter any domain to see estimated visits, global and category rank, bounce rate, pages per visit and visit duration. You can compare a site against competitors, look at its audience demographics and set alerts for competitor changes. Our guide on how to check website traffic explains how to read these numbers.
Marketing channels and SEO
Similarweb splits a site's traffic by channel, such as direct, search, referrals, email, social and display ads. The free version shows only the top three channels and a few top keywords. The SEO plans add keyword research, keyword gap analysis, a rank tracker, a site audit and backlink data.
AI search visibility
Newer plans track how often your brand appears in answers from AI assistants. They also show which sources those answers cite, the sentiment of the mentions and how much traffic AI tools send to sites.
Ad intelligence, API and MCP
The top self-service plan shows competitors' search, display and social ads and estimated ad spend. Business packages add APIs, bulk data feeds and an MCP server for AI workflows. The API can also be bought on its own through sales.
Where does Similarweb's data come from?
Similarweb says it combines four sources. These are first-party analytics from site owners who connect them, an anonymous contributor network on millions of devices, public data, and partner data from ISPs and measurement companies. The figures are estimates, so they will not match your own analytics exactly.
