Domain Influence is a score that gives you an overall information about the authority of a domain. The score ranges from one to 100, with higher scores corresponding to a greater domain influence and authority.
Domain Influence is calculated by evaluating multiple factors, including linking root domains and the number of total links. This score can be also used when comparing websites or tracking the "ranking strength" of a website over time.
Generally speaking, sites with a very large number of high-quality external links (such as Wikipedia or Google.com) are at the top end of the Domain Influence scale, whereas small businesses and websites with fewer inbound links may have a much lower score.
