In the context of SEO (Search Engine Optimization), “Trust Flow” is a metric developed by Majestic SEO to measure the quality of links pointing to a website. It is intended to give an indication of the trustworthiness and credibility of a site based on the quality of the websites that link to it. Trust Flow is calculated on a scale from 0 to 100, with higher scores indicating a greater degree of trust.

The Trust Flow metric is derived from an analysis of the web’s top sites and their linking patterns. A site linked by a highly trusted source is likely to be considered trustworthy itself. Therefore, a link from a website with a high Trust Flow is more valuable than a link from a low-Trust Flow site.

Trust Flow is often used alongside another Majestic metric called Citation Flow, which measures the quantity of links pointing to a site, regardless of quality. Together, Trust Flow and Citation Flow can provide a comprehensive view of a website’s link profile, helping SEO professionals to understand both the popularity and the trustworthiness of a website. High Trust Flow is generally seen as an indicator of content that is authoritative and valuable, contributing positively to a website’s SEO performance.
