About Similarweb
Similarweb estimates traffic for almost any website and app, so marketers, analysts and investors can compare competitors without access to their analytics. It shows visits, engagement, traffic sources, referring sites, audience geography, top keywords in paid and organic search, and newer data on traffic from AI chatbots. Its SEO and GEO toolkit adds keyword research, rank tracking and site audits, while separate products cover sales prospecting, ecommerce and investor research. Free website traffic checkers give a limited view; full access comes through paid plans for individuals and teams, with enterprise contracts for most of the data products, and a free trial. The company is listed on the New York Stock Exchange. It is best for market and competitive research rather than day-to-day technical SEO, and estimates for small sites can be rough. It runs in the browser, with a Chrome extension.
Best for: Marketers and analysts benchmarking competitors' traffic and channels.
