Trust flow和Citation Flow是majestic的两个重要参数。
官方解释
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.
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.

Citation Flow represents an evolutionary leap from our old metric – ACRank – and predicts how influential a URL might be based on how many sites link to it. Links are now not all created with equal weight – and because a strong link will have a relatively stronger influence on URLs, Citation Flow is based on stronger, iterative mathematical logic than the old metric of ACRank.
ACRank is a very simple measure of how important a particular page is by assigning an integer value from 0 (lowest) to 15 (highest) depending on number of unique referring external root domains.
ACRank has now been replaced with Citation Flow, providing a more sophisticated measure of link quantity.
Trust Flow衡量的Link的质量，citation flow衡量的是引用的数量。
Brian Dean的理解
Brian dean关于Trust Flow是seed instance的认识是对的，官网解释：
Trust Flow is the same calculation as Citation Flow, but we only START with domains that we know were created and curated by humans. I won’t go into detail about how these sites were initially selected, but there are hundreds of thousands and they have been peer reviewed.
