Referring Domains is the number of unique websites that link to a domain or URL. If one website links multiple times, it is still counted as one referring domain. In most cases, links from many relevant and trusted websites are stronger than many links from only a few sources. This metric is used to measure the diversity and strength of a backlink profile.
Referring Pages is the number of individual web pages that contain links pointing to a domain or URL. Unlike Referring Domains, this metric counts every linking page separately, even if several pages come from the same website. It helps show how many pages are linking to a site and how those links are distributed.
View definitionDomain Rating (DR) is a metric developed by Ahrefs that estimates the overall strength of a domain’s backlink profile on a logarithmic scale from 0 to 100. It is based mainly on the number and authority of referring domains linking to the website. A higher Domain Rating usually indicates a stronger backlink profile, but it does not guarantee better rankings, more traffic, or higher-quality content.
View definitionTrust Flow is a metric developed by Majestic that estimates the quality of backlinks pointing to a domain or URL. It is based on how closely a site is connected to a set of trusted seed sites. A higher Trust Flow usually indicates stronger link quality, but it should always be evaluated together with Citation Flow, topical relevance, and the actual referring domains behind the score.
