Website Traffic Checker

Curious how much traffic a website gets? Enter any domain and this free checker first looks up the site's modelled monthly visits, global and country rank, bounce rate, pages per visit and average visit duration (Similarweb), plus its registration date and age. When live traffic data is unavailable for a site it falls back to a clearly labelled rank-based estimate. Figures are modelled data for comparison, not first-party analytics.

How it works

This checker tries live traffic data first. It asks Similarweb's public data service for the domain: monthly visits for the most recent months, the site's global and country rank, and engagement figures (bounce rate, pages per visit, average visit duration). When Similarweb returns data, the result says so — the source line under the results reads 'Traffic data: Similarweb'. If Similarweb has no data for the domain (common for new or very small sites) or the request fails, the checker falls back to the Tranco list, a research project that ranks the top million or so domains by combining several traffic data providers over a rolling 30-day window, and models an estimated monthly visits range from that rank using a power-law relationship — web traffic follows one: the top sites get billions of visits and traffic falls off steeply and predictably as rank increases. Fallback results are labelled 'Estimate — live traffic data unavailable for this site', and the estimate is deliberately shown as a range (roughly half to double the central value) because rank-based modelling is a size signal, not a measurement. Either way, the domain's registration date is read from the global RDAP directory (the successor to WHOIS) to work out the domain's age, and results are cached for a day so repeat checks are instant. Small and brand-new domains often appear in neither source yet; that means not enough traffic has been measured for them, not that they get zero visitors.

Frequently asked questions

How accurate is the traffic estimate?

When the result line says 'Traffic data: Similarweb', the visits and engagement figures are Similarweb's own modelled numbers — the same data behind its public traffic checker — which are estimates built from its panels and partnerships, not the site's analytics. When the result instead shows the labelled rank-based estimate, that figure is inferred from the site's global rank (Tranco) using a power-law relationship and is shown as a wide range for that reason; for small sites it can be off by a lot. Either way, treat the numbers as a rough size signal for comparing sites, not analytics.

Why does my site show no rank?

Probably because it is new or receives little traffic. The Tranco list tracks the most-visited million or so domains, and many legitimate small sites are simply not in it yet. No rank is not a judgment on the site.

What is the Tranco rank?

Tranco is a research-grade ranking of domains built for stability by combining data from providers such as Cloudflare, Chrome UX data and others over a rolling 30-day window. It is maintained by researchers at several universities and is free to query.

Is this the same as the Ahrefs or Similarweb traffic checker?

Partly. When Similarweb has data for a domain, the monthly visits, ranks and engagement figures shown here are Similarweb's own modelled numbers, as in its free checker. Ahrefs uses its own separate data and models, so its figures will differ. And when Similarweb has no data for a site, this checker falls back to a rank-based estimate and labels it clearly as an estimate.
