Domain Traffic Lookup

API

One domain per request. While the domain is being collected the response says status: "pending" — poll again every few seconds. Machine-readable usage notes for both this and the availability checker live at /skill.md.

Frequently asked questions

Where does the data come from?

Monthly visits and traffic sources are estimates collected from Similarweb's public web analytics. Numbers are model-based estimates, not the site's own analytics, so treat them as directional — good for comparing sites and spotting trends, not for billing.

Why does a domain show "collecting"?

The first time a domain is requested it is queued for collection. Results usually land within a few seconds while a collector is online; the page keeps polling for a short while and the API returns status "pending" until data is stored.

How fresh are the numbers?

Similarweb publishes a month's data around the 10th of the following month. A domain that already has the latest published month is served from cache; it is re-collected automatically once the next month is published.

What do the source percentages mean?

The share of that month's visits arriving from each channel: direct, organic and paid search, referrals, organic and paid social, email, generative AI assistants, affiliates and display ads. A blank cell means the source was not reported for that month.
