Check any website's traffic for free. Monthly visits, bounce rate, traffic sources, top countries, keywords, and quality score.
Type a domain into the box and Traffic Lens returns a profile of that site in a few seconds. There is no account to create, no credit card, no trial period, and no limit on how many domains you look up. You do not need to own or verify a site to check it, which is the whole point — this is built for looking at other people's websites, not just your own.
Traffic figures are estimates, and we say so everywhere rather than in a footnote. Nobody outside a website's own analytics can see its exact visitor count; every traffic tool on the market, including the expensive ones, is modelling from sampled signals. Treat the numbers as a reliable sense of scale and trend — is this site ten thousand visits a month or ten million, and is it growing or shrinking — rather than as an audited figure. Where we cannot source a number honestly, the page says so instead of filling the gap with a guess.
Competitor research. See roughly how big a rival is, which channels bring them traffic, and which countries they are strongest in. Compare up to five domains side by side to find where you are ahead and where you are not.
Checking a site before you deal with it. Before paying for a guest post, a sponsorship, an ad placement, or a backlink, check whether the site actually has the audience it claims. A domain with a professional design and almost no traffic is a common and expensive surprise.
Due diligence on a purchase. If you are buying a website or a business, traffic trend over time tells you whether you are buying something growing, flat, or quietly in decline.
Technical checks. The toolkit below covers the infrastructure side — DNS records, SSL certificates, HTTP security headers, redirect chains, subdomains, email authentication, and robots.txt — so you can go from "how big is this site" to "how is it actually built" without leaving the page.
Every tool here is free, with no signup, no API key, and no scan limit. The tools run on an edge network and lean on public data sources — Certificate Transparency logs, public DNS, RDAP registry records, and published rankings — which keeps the cost of answering a query low enough that gating it behind an account would cost more in friction than it would ever earn.
Traffic estimates are strongest for large and mid-sized sites and weakest for small ones; a site with a few hundred visits a month may not be measurable at all, and we would rather return nothing than invent a number. Technical results — DNS, SSL, headers, WHOIS, redirects — are read live from the domain itself and are exact, not modelled. Anything behind a login, rendered only after JavaScript runs, or deliberately blocked to automated requests will not appear. Where a check cannot complete, the result says which one failed rather than quietly scoring it as zero.
