# Data and methodology

> Learn where Rankfield's link data comes from, which web graph release it uses, and what the numbers can and cannot tell you.

Site Strength and the referring-domain endpoints read the Rankfield web graph. It is built from public web crawl data: a large sample of the links on the pages those crawls fetched, not a complete index of the web. These pages explain the data so you can use it correctly.
