Similarweb provides multi-channel digital intelligence covering website traffic, retail pricing, mobile app usage, sales prospecting, and AI search engine visibility across global markets.
Similarweb is a digital data intelligence platform engineered to measure and benchmark online presence across global web, mobile, retail, and AI conversational ecosystems. Drawing on an indexed repository that includes over 100 million websites, 4 million mobile apps, and hundreds of millions of product SKUs, the platform gives organisations visibility into competitor strategies, traffic origins, and customer acquisition channels. Core solution areas span Web Intelligence for traffic and search benchmarking, App Intelligence for mobile store and technographic tracking, Sales Intelligence for intent-driven pipeline prospecting, and Stock Intelligence for corporate performance forecasting. In addition to traditional SEO and paid advertising metrics, the platform includes dedicated AI Search Intelligence capabilities. These allow teams to track traffic and brand citations across emerging answer engines and AI chat services, including ChatGPT, Claude, Perplexity, Gemini, DeepSeek, and Grok. For ecommerce brands and retail buyers, Similarweb provides SKU-level price intelligence, buy box tracking, and category benchmarking across major marketplaces including Amazon. Access is available through web interfaces, automated dashboards, browser extensions, and developer APIs.
Unlike standalone SEO or web analytics utilities, Similarweb combines macro web traffic estimation with multi-engine AI search attribution, SKU-level retail price intelligence, and mobile app usage metrics within a single dataset spanning ten years of historical data.
