Domain authority vs page authority (Which Wins in 2026?)

Domain authority (DA) is a Moz metric that predicts how well a domain ranks in search results (https://moz.com/learn/seo/domain-authority). It scores from 1 to 100. Higher scores correlate with stronger ranking potential. DA measures the overall strength of an entire domain based on its entire backlink profile.

Domain authority evaluates the quantity and quality of all inbound links to a domain. It considers factors like link diversity, link velocity, and the authority of linking domains.

Page authority (PA) is also a Moz metric, scored 1 to 100 (https://moz.com/learn/seo/page-authority). It predicts the ranking potential of a single page rather than an entire domain. PA evaluates the backlink profile of one specific URL.

A page with strong PA can rank well even on a domain with modest DA. This happens when the page attracts high-quality editorial links from authoritative sources.

DA and PA are deeply connected. A domain with high DA typically has many pages with high PA. But the reverse is not always true. A single high-PA page on a low-DA domain does not automatically lift the entire domain.

Google evaluates both page-level and domain-level signals. The search algorithm considers the page's specific link profile and the domain's overall reputation. Google's ranking systems documentation confirms that both page quality and site-wide authority contribute to search rankings (https://developers.google.com/search/docs/appearance/ranking-system-guide).

PA matters more for pages that compete on specific queries. A well-optimized page with strong PA can outrank pages from higher-DA domains. This is common in long-tail keyword spaces.

New pages on low-DA domains can still rank if they earn targeted editorial links. PA is a better metric for evaluating specific content assets.

DA matters more for broad competitive queries. Domains with high DA enjoy a trust advantage across all their content. New pages on high-DA domains rank faster because of inherited trust.

For competitive head terms, DA often determines the playing field. A page from a DA 90 site will almost always outrank a page from a DA 30 site for the same query.

Data from 2025 correlation studies shows that page-level metrics are becoming more important. Google's passage ranking and relevant passage indexing push importance toward specific content quality.

However, domain-level trust remains a top-tier ranking factor. The two metrics work together rather than in opposition. Search Engine Journal's 2025 ranking factors study confirms that domain authority and page authority both correlate with search position (https://www.searchenginejournal.com/ranking-factors/).

Use DA for vetting link prospects. A site with DA below 20 is unlikely to pass meaningful equity. Use PA for evaluating specific pages for link placement. A page with PA above 30 is a reasonable target.

Both metrics have limitations. They are third-party estimates, not Google scores. Use them as directional guidance, not absolute truth.

Audit your backlink profile quarterly using both DA and PA. Filter for links from high-PA pages on mid-DA domains. Those are your most valuable assets. Note the gap between your best-linked pages and your competitors' best-linked pages. Identify which of your pages have low PA relative to their content quality. Build links to those pages specifically. Audit quarterly.
