Data methodology

Draft prepared in-house for professional legal review. Not legal advice.
Measured data
Measured figures come from our own analytics snippet running on a site whose owner installed it. They are counts, not models, and are labelled MEASURED.
Estimated data
Estimates come from our own models, trained only on measured sites whose owners explicitly permitted modelling use, plus public signals from our crawl. Every estimate carries a range, a confidence score and the model version that produced it.
Public signals
Authority, pages indexed, referring domains, page speed and technology detection come from our own crawl of public pages.
What we do not do
We do not buy or resell third-party traffic panels or clickstream data. We do not publish advertising spend data, because we do not hold it. Where we lack data we say so, rather than filling the gap with a plausible-looking number.
