There will be cases where a page belonging to a domain with high DA will not rank highly. In this case, DA won’t be able to separate the value of WordPress’ domain from all the free WordPress subdomains that operate as individuals’ personal sites.Īlso, although DA is a relatively reliable predictor of SERP placement, it’s not perfect. However, consider a site such as WordPress. In most cases, the inability to separate subdomains may not be an issue. This means that it cannot distinguish subdomains, and does not measure the authority of individual pages within a domain (that would be Page Authority). The most significant point to clarify when it comes to Domain Authority is that it only measures the authority of a root domain. Since it can be difficult to calculate the Page Authority of new pages, Domain Authority works better as an overall measure when evaluating link value.
