Similarweb

Similarweb is competitive traffic, audience, keyword and ad intelligence on any website, plus AI search visibility, from single-seat plans to enterprise.

Similarweb answers a question a company's own analytics cannot: how are the other sites in the market doing? Type in any domain and it estimates visits, engagement, device split, audience demographics and the channels that traffic came from, modelled from direct measurement, a contributory network, partnerships and public data. It is made by Similarweb, an Israeli data company founded in 2007 and listed on the New York Stock Exchange. Traffic and engagement benchmarking lines up several competitors in one report, with a marketing channel breakdown, audience demographics and interests, website segment analysis by folder or subdomain and custom industries of hundreds of sites. The SEO tier adds keyword research measured by real traffic share rather than search volume, a rank tracker that watches AI Overviews, a site audit and backlinks, and the AEO tools, which report AI brand visibility across chatbots with sentiment and citation analysis. The Ads tier adds competitors' search, display and social creatives and estimated spend. Competitor alert emails, custom dashboards with templates, a Data Exporter with scheduled reports, Excel and PDF downloads and a browser extension are on every plan, with the AI Trend Analyzer add-on and AI Studio natural-language queries on top. A REST and Batch API, Looker Studio, Power BI and Tableau connectors, Snowflake and Databricks data feeds, single sign-on and an MCP for AI workflows serve enterprise data teams. Similarweb suits solo marketers and consultants sizing a market, SEO and content teams tracking organic and AI search visibility, growth teams benchmarking competitors' channels and ads, enterprise data teams that want feeds into a warehouse, and investors and analysts reading digital demand. It is sold per seat on three self-serve packages, Competitive Intelligence, then with SEO and AEO, then with Ads, each one user with a trial and a monthly pool of data credits, billed monthly or annually, and on a Businesses and Enterprises tier priced by sales where more seats, single sign-on, the API, the BI connectors and the longest history live. The plan cards list every tier. In daily use Similarweb benchmarks traffic and engagement against competitors, sizes a digital market and spots demand trends, researches keywords by real traffic share, tracks brand mentions inside AI chatbot answers, analyses competitors' ad creatives and spend, builds the competitive dashboard for the leadership team and schedules data exports to a warehouse. It sits beside a company's own analytics platform and its BI tools rather than replacing them.
