Free online tool
Pick a provider and get its numbers for any website: the Ahrefs Site Explorer overview — Domain Rating, backlinks, referring domains, organic keywords and traffic — or Similarweb visits, traffic channels, every country, top keywords and similar sites. One provider per check, straight from the same live API our customers build on.
What you'll see
Each check spends one real provider call, so you choose which. Every number in the report says where it came from and when it was fetched.
Domain Rating on the familiar 0–100 scale with URL Rating, Ahrefs Rank, backlinks, referring domains, organic keywords and traffic, traffic value, the top country and paid keywords — one Ahrefs call, Ahrefs' own figures, never recalculated.
Total monthly visits with bounce rate, pages per visit and time on site, global rank, the traffic channels, every visitor country, top keywords and similar sites — the context a raw traffic number lacks.
The paid API answers with Domain Rating, Ahrefs organic traffic and Similarweb visits side by side — both in one call. The free tier carries 100 credits a month; get a key.
FAQ
Three per day, per visitor, resetting at midnight UTC — each behind a quick captcha so the tool stays fast for humans. Need more? A free API key carries 100 credits every month.
Each check is a real, live lookup. Asking one provider at a time keeps the tool free and fast. The paid API returns both providers in one call — Domain Rating, organic traffic and Similarweb visits side by side — and the free tier carries 100 credits a month.
The Ahrefs view — the Site Explorer overview — is Ahrefs data; visits, engagement, traffic channels, countries, keywords and similar sites are Similarweb data. Every report footnotes which provider answered and when.
No third-party tool sees a site's analytics; traffic figures are estimates and authority scores are one vendor's model. Reading two independent estimates side by side is the honest way to use them — the API does exactly that, a technique we wrote up here.
Recently checked domains are served from cache with their original fetch date shown. Popular domains stay warm, which is also why the paid API charges 0 credits for cache hits.
Everything in this report — and the other provider's numbers beside it — is one API call. The free tier includes 100 credits a month, more than 30x the daily tool limit.
