Similarweb
Similarweb is a digital market intelligence platform estimating website and app traffic, competitor channels, SEO and ad data, and brand visibility in AI search.
About this tool
Similarweb estimates how much traffic websites and apps receive and where it comes from, giving marketers, analysts and sales teams a view of competitors they cannot get from their own analytics. Users benchmark performance, size markets, follow trends and audience loyalty, and see which channels, from search to display and social ads, drive a competitor’s growth.
The company sells its data as several products: Web Intelligence for research and SEO, App Intelligence, Sales Intelligence for finding and enriching prospects, Retail Intelligence for Amazon and marketplace insights, and AI Search Intelligence for measuring how often a brand appears in answers from AI search tools and chat assistants. Data is also available through an API, and AI-powered assistants help users query the insights.
