What is the Number of Linking Root Domains?

The term “linking root domains” refers to the number of unique domains linking to your website. Unlike total backlinks, which count every link pointing to your site, this metric focuses on the diversity of domains. For instance, if your site receives multiple backlinks from several pages of the same domain, it still counts as one linking root domain.

Imagine your website is a candidate running for an election, and every other website is a voter. The number of linking root domains represents the number of unique voters who support you. Just as in an election where the support of a diverse group of voters is crucial, in SEO, obtaining links from a wide range of domains boosts your site’s credibility and ranking on search engines.

Why is the Number of Linking Root Domains Important in SEO?

The number of linking root domains is a critical metric because search engines, like Google, view each link as a vote of confidence. The logic is straightforward: the more domains (voters) you have vouching for your content’s quality and relevance, the more trustworthy your site appears. This, in turn, positively impacts your SERP rankings. Moreover, search engines use this metric to gauge a site’s authority and relevance for specific search queries. A higher number of diverse linking root domains indicates that a wide range of external sources find your content valuable enough to link to, enhancing your site’s perceived usefulness and authority.

How the Number of Linking Root Domains Affects SEO?

Studies have consistently shown a direct correlation between the number of linking root domains and a website’s ranking on SERPs. For instance, a study by Moz found that domains ranking in the top positions of Google search results typically possess links from more unique domains compared to those ranking lower. This highlights the sheer impact of domain diversity on SEO performance. Furthermore, a report by Backlinko reinforced this, demonstrating that the number of linking root domains was one of the best indicators of a page’s success in SERPs. These statistics underscore the indispensable role that a diverse link profile plays in elevating your site’s ranking and visibility online.
