Paste a list of domains. For each one you get its worldwide Chrome traffic tier, its Tranco rank and its Common Crawl PageRank, and the list comes back sorted from most to least visited. No account and no credit card.
CrUX world and CrUX by country. Every month Google publishes the list of sites most visited by Chrome users, grouped in tiers: Top 1K, 5K, 10K, 50K, 100K, 500K and 1M. It is the closest measure to real traffic, but it stops at the first million. It also exists country by country: a site outside the worldwide Top 1M is often well ranked in its own country, hence the second column, which then orders the list.
Tranco rank. A research ranking that combines several popularity lists over a month to resist manipulation. It separates two sites in the same tier.
Common Crawl PageRank. The domain's score out of 100, on a logarithmic scale, in Common Crawl's public link graph; the exact rank shows on hover. It does not measure traffic but the site's place in the link network. A heavily visited site that is rarely cited, or the reverse, shows up at once.
NicheObserver score, on demand. It goes down to the Top 50M, where public lists stop at one million, and gives the site's main market. Useful for long-tail sites that the other columns leave “unranked”. Its tier being the worldwide CrUX ranking extended further, it replaces the CrUX world column once shown.
Google traffic (Ahrefs). The organic traffic estimated by Ahrefs, read on its public page ahrefstop.com, for the roughly 370,000 sites it covers. The small curve shows the last 24 months: green when traffic rises, red when it falls, grey when flat. The percentage compares the last three months with the same three months a year earlier. The “ahrefs” badge next to the domain opens the full page.
Google listing. What Google shows when you search the brand without the extension (“espace-oriental” for espace-oriental.fr): a business listing or a Knowledge Panel. Linked: its Website link points to the domain, so it still sends visits. Closed: linked, but the business is marked closed. Another site's listing: the listing found points elsewhere; its name tells whether it is a namesake or the same business moved to another site. No website: the listing has no website. Each cell opens the Google search. The column appears once at least one domain of the list has been checked.
Discover. The 📱 icon shows for sites whose articles appeared in the Google Discover feed in France; a single site gets its own block under the traffic sources. Source: GNewsalyzer, which has captured that feed continuously since May 2025 (about 5,500 articles a day). The curve counts, per month or per week, the site's different articles seen in Discover: articles, not visits. The purple line is its share of all articles captured over the same period, per thousand, so it does not rise just because the capture grows. The link under the curve unfolds its latest articles, with their date and section.
The public Chrome and Tranco lists stop at the first million sites. A site can have real traffic and stay below, especially if it targets a single country. The NicheObserver score, which goes down to the Top 50M, still ranks it.
No. It is a rank, not a volume, and it is published in tiers. It counts navigations by Chrome users who share usage statistics, on desktop and Android. Between two neighbouring tiers the traffic gap can be large.
Either it does not appear in Common Crawl's link graph, or its extension is not one of the 37 the index covers. It is not a judgement on the site.
Up to 500 per run. The first three columns are read in a single pass through lists hosted here, without any request to the sites: the result arrives in a few seconds.
From the public CrUX lists (the zakird/crux-top-lists mirror), the month's Tranco list, Common Crawl's link graph and, on demand, the NicheObserver API. Each source's month is shown under the table.
