SimilarWeb is a web analytics and market intelligence platform that provides estimated traffic data, traffic source breakdowns, and audience insights for any website, including competitors whose internal analytics you wouldn’t otherwise have access to.
It’s commonly used to benchmark overall traffic and channel mix against competitors, understand broader industry and market trends, and identify which channels (organic, paid, social, referral) drive the most traffic for comparable businesses.
Because SimilarWeb’s data is estimated rather than pulled from a site’s actual internal analytics, figures should be treated as directional benchmarks rather than perfectly precise numbers.
We use competitive traffic benchmarking within our SEO Audits & Reporting service.
