| Important considerations |
It focuses on aggregate traffic and performance metrics. It does not replace event-based product analytics, conversion funnels, session replay, heatmaps, or user-level journeys, and a Cloudflare account is required. | Similarweb estimates external market and competitor traffic rather than replacing first-party site instrumentation; depth, countries, history, and APIs vary by package. |
