What it does
Similarweb provides digital market intelligence across websites, apps and commercial channels. Its wider platform includes competitive benchmarking, search and AI-discovery research, retail analysis and sales intelligence, with limited public data and paid packages for deeper analysis or data access.
Similarweb estimates how competing websites perform when their analytics accounts are unavailable to you. It blends participating sites' data, a contributor network, partners and public information into modeled estimates. These figures describe the wider market; they are not a substitute for your own site's measured event data.
Compare a set of websites
In Website Research, open Website Analysis and enter a domain. Select +Compare to add up to four competitors, then set the period, country and All Traffic, Desktop or Mobile view. Available countries depend on the package. Visits Over Time shows daily, weekly or monthly trends, while the channel breakdown helps explain how each site attracts visitors. The Geography view compares the five leading countries for the selected sites.
You can start with the free public website checker without an account. Public reports contain selected traffic estimates, countries and keywords; the visible marketing-channel preview is limited, and downloading a PDF requires registration. Paid packages expand the data and tools. Business packages can include up to 37 months of history, chosen country coverage and API or bulk-data access.
