Similarweb
Website traffic, competitor and market intelligence for marketers
Similarweb is a sEO tools tool for Enterprise and Agencies, offered as freemium ($129/mo). Founded in in 2007.
About Similarweb
Similarweb is a digital market intelligence platform founded in Tel Aviv in 2007 by Or Offer and listed on the New York Stock Exchange since 2021. It estimates traffic, engagement, audience and marketing channels for almost any website or app by combining panel data, public data and direct measurement from connected sites. The core job: see how competitors and markets perform online without their analytics.
The platform is sold in suites. Competitive Intelligence covers website traffic, engagement, demographics, traffic sources and benchmarking. The SEO suite adds keyword research, keyword gaps, rank tracking, backlinks and site audits, while AEO tools track brand visibility and citations in AI assistants. Ads intelligence covers paid search, display and social creatives. Self-serve plans are for one user and start at $129 a month for AEO alone or $199 for Competitive Intelligence; Business packages add longer history, country filters, API access and AI Studio.
Similarweb fits marketers, analysts, investors and agencies who need market share and competitor traffic numbers, not just SEO rankings. Its estimates are modelled, so small sites can be inaccurate, and the full value sits in expensive custom contracts. Semrush and Ahrefs are stronger and cheaper for day-to-day SEO, while SE Ranking suits agencies on a budget.
In September 2025 Similarweb launched an MCP server that lets AI tools such as Claude, Cursor and n8n query its traffic, keyword and app data directly. Before buying, use the 7-day free trial to check estimates against a site whose real analytics you know.
