Website traffic checker tools, and which to trust

Every website traffic checker gives you an estimate, not a count. Only the site's owner knows its real traffic. That said, the free checkers are good enough to answer the questions most people actually have: is this competitor bigger or smaller than us, is their traffic rising, and does it come from search, ads or somewhere else.

For total visits to a large site, start with Similarweb's free pages. For search traffic to any site, use Ahrefs', Semrush's or SE Ranking's free checker. For a sanity check on popularity that involves no modelling of visits at all, use Cloudflare Radar.

Two different numbers

Traffic checkers produce one of two estimates, and mixing them up causes most of the confusion.

Total visits. All traffic from every source: direct, search, social, referrals, email. These estimates come from panels and data partners. Similarweb describes blending data from sites that connect their analytics, an anonymous contributor network, and partners such as ISPs and measurement companies (Similarweb's data page). Semrush's Traffic & Market toolkit works in a similar way.

Organic search traffic. Only visits from Google. These are modelled from the keywords a site ranks for, the search volume of each keyword and the share of clicks each position typically gets. Ahrefs, SE Ranking and Semrush's Domain Overview give you this number.

A brand with a big newsletter and a popular app can have modest organic traffic and huge total visits. Decide which question you are asking before picking a tool.

The website traffic checkers compared

Prices below were read from each vendor's own pricing page on 4 October 2026.

Similarweb

Similarweb's free page for a domain shows total visits over the last three months, the month-on-month change, bounce rate, pages per visit, average visit duration, the split of traffic sources and the top countries. For a competitor comparison on a big site, that free page answers most of what you want.

Best at: total visits and traffic mix for large sites, including the share that comes from direct, referral and social rather than search.

Limits: small sites. Similarweb says that when traffic is too low to support an accurate estimate it shows "Not enough data" or N/A (its help article). Paid plans are mostly sold through sales; the only published figure is "from $125/mo" in the pricing page's metadata, and we found no plan names or limits to go with it.

Semrush

Semrush's free website traffic checker can be used once a day without an account and shows total visits, unique visitors, pages per visit, visit duration, bounce rate, traffic sources, top pages and keywords. Semrush says its estimates model "aggregated browsing patterns, search activity, and verified traffic data from trusted partners and public sources".

A free account adds 10 Domain Overview queries a day, which show organic search estimates. The full traffic toolkit is a separate subscription: Semrush's knowledge base lists Traffic & Market Pro at $289 a month for one user, and free users can only open sample domains in it.

Best at: one place for both numbers, total visits and organic search, if you already use Semrush for SEO.

Limits: the daily allowance runs out quickly once you start comparing competitors, and the full traffic data costs more than most SEO plans.

Ahrefs

Ahrefs' free traffic checker gives search traffic estimates for any website or page. The detail, top pages, keywords, paid traffic and history, sits in Site Explorer, which needs a paid plan from $129 a month (Lite, monthly billing).

Best at: organic search traffic, and the pages and keywords behind it, from a large keyword database.

Limits: it is search only. It will tell you nothing about a site that lives on direct traffic, email or social.

SE Ranking

SE Ranking's free traffic checker is, in its words, "Free to check", and estimates organic and paid search traffic, with top pages, keywords and countries. Its paid Core plan is $129 a month, or $103.20 a month billed annually, with a 14 day trial and no card.

Best at: a free second opinion on search traffic. Run the same domain through Ahrefs and SE Ranking and you get a feel for how much the estimates disagree.

Limits: search only, like Ahrefs.

Cloudflare Radar

Cloudflare Radar ranks domains by how many people look them up through Cloudflare's 1.1.1.1 DNS resolver. It gives an exact order for the top 100 domains, refreshed daily, and otherwise places domains in buckets: top 200, 500, 1,000 and so on up to the top million, refreshed weekly (Cloudflare's documentation).

Best at: a check that does not depend on keyword models or panels. If a checker claims a competitor gets ten million visits a month and they are not in Radar's top million, something is off.

Limits: no visit counts at all, and buckets are too coarse to compare two small businesses.

Your own analytics, the only real numbers

Google Analytics counts your actual visits and Search Console your actual clicks from Google, with 16 months of search data. Neither shows a competitor, but both are how you calibrate every tool above. Look up your own domain in each checker and compare: if one reads you at half your real traffic, it probably reads sites like yours low too.

Using estimates without being misled

Three rules.

1. Compare, do not quote. "They get roughly three times our organic traffic" survives a large error. "They got 41,200 visits in August" does not.
2. Watch direction over months. A steady rise across six months of estimates is a real signal even when every monthly figure is wrong.
3. Use the same tool for every site. Each tool is wrong in its own consistent way, so comparing Similarweb for one site with Ahrefs for another is meaningless.

What the published studies found, tool by tool, is on how accurate traffic estimates are. For a step-by-step method, see how to check a competitor's website traffic, and for where the visits come from, checking a site's traffic sources.

If you want the number tracked, not checked

Ours, so judge accordingly. Figo records each tracked competitor's estimated organic traffic and Google keyword positions once a week, and reports changes in a Monday briefing alongside their ads, new pages, social posts and reviews. The traffic figures are estimates from search data, not real visits, with the same limits as every search-based checker above. Plans start at $49 a month for 3 competitors.

Do not pick Figo if you need total visits including direct and social traffic, or a one-off number. A free checker is the right tool for a one-off.

Which checker to use

• Big competitor, total visits: Similarweb's free page.
• Any competitor, search traffic: Ahrefs' or SE Ranking's free checker, ideally both.
• Both numbers in one place, a few times a week: Semrush's free checker and free account.
• Is this site even as big as it claims: Cloudflare Radar.
• Your own site: Google Analytics and Search Console, never an estimate.
• The same competitors, every week, without remembering to look: a monitor such as Figo.
