About DomainRank

DomainRank provides insight into the relative popularity and influence of domains. We also show how that influence changes over time.

DomainRank shows where influences comes from and provides insight into how to get more.

How it works

We have developed a link-analysis method to determine a “score” for each domain. Rather than simply counting the number of inbound domains, we use a PageRank-based algorithm that gives more influential sites more “authority” when they link to other domains. It’s analogous to referrals: you’re more likely to trust a referral from a trusted, authoritative source. We treat domains as authorities and their links as their referrals.

Once we have scores for every domain (over 60 million of them!), we determine their DomainRank relative to every other domain. For instance, Facebook and Google usually have DomainRank 1 and 2, respectively, because of how many (and how many good) domains link to them.

What DomainRank means

We provide several important types of information via DomainRank, each of which can be used in many ways.

  • DomainRank and DomainRank Score reflect the relative popularity or influence of domains.
  • Changes in DomainRank and Score may reflect significant growth, changes in visibility, or other changes in other aspects of business.
  • Inbound links reflect the “opinions” of other sites. Examining link sources can provide insight into who is finds the site credible or influential, and lists of such sites can be a resource for competitive analysis and link building.
  • Outbound links reflect the likelihood of sharing influence, and they impact the “weight” or influence that a domain confers to other domains that it points to.
