Citation Flow and Trust Flow are scoring metrics from Majestic that range from 0-100. Citation Flow is a score which reflects the quantity of links that point to any given website. Citation Flow does not care whether a link is of good-quality, or poor quality. Trust Flow represents the quality of links that point to URLs and websites. A web page with higher Trust Flow than Citation Flow will usually have good-quality links.  A flow ratio can be derived by dividing Trust Flow by Citation Flow to provide a simple score for links.
