We collect limited information through our browser extension in accordance with our privacy policy and perform in-depth analysis using in-house crawlers. Our unique methods ensure only actively visited websites are included in the lists, including pages that traditional crawlers can't reach.

The data is being updated and added to every day. By default, lookup results can be up to three months old but this can be lowered down to one month. Live results are real-time.

Website traffic is tracked using our browser extensions with over 2M users. The install base provides a large enough sample set to determine which websites receive more traffic than others, resulting in a relative traffic indicator.

Reselling or sharing our data is prohibited by our terms of use. If you're an Enterprise customer and would like to apply for an exception, please contact us.
