How Domain Authority and Page Authority Affect Link Juice Passed
Domain Authority and Page Authority are two metrics created by Moz that can help indicate how much link juice or link equity a website may pass.
Domain Authority is a score from 0 to 100 that represents the overall authority and quality of a domain based on its entire link profile. Higher Domain Authority scores generally indicate domains that pass more link juice and value when they link out to other sites.
Page Authority is a similar score from 0 to 100, but it represents the authority and quality of an individual page based on its own link profile. Higher Page Authority scores generally indicate pages that pass more link juice compared to lower scoring pages, even within the same domain.
Both Domain Authority and Page Authority are calculated using machine learning models that analyze a page’s entire link profile and compare it to Google’s search results. They aim to predict how well a page may rank based solely on its links.
While they are not perfect measures, in general higher Domain Authority and Page Authority scores indicate pages and domains that:
- Are seen as more authoritative and trustworthy by search engines.
- Pass more link equity and value when linking out to other websites.
- Provide a stronger positive endorsement signal for the sites they link to.
So a link from a page or domain with a high Domain/Page Authority score will likely pass more link juice and help the linked website more compared to a link from a page or domain with a lower score.
This is because search engines trust links from more authoritative sources more and assign them more value. The machine learning models aim to predict this perceived value based on link data.
In summary, higher Domain Authority and Page Authority scores generally indicate pages and domains that pass more link juice and provide more value when linking out to other websites. This is due to the perceived authority, trustworthiness, and positive endorsement signal associated with links from higher scoring sources.
