Domain Authority / AiSEO Authority
TL;DR
Domain Authority is a third-party metric predicting how well a site will rank. AiSEO calculates its own authority score combining backlink strength, content quality, and technical health.
Explain Simply
Domain Authority is like a school's reputation. A student (page) from a prestigious school (high DA domain) is assumed to be smart, even before being tested. But it's a reputation score, not an official grade.
Domain Authority (DA) is a metric developed by Moz that predicts a website's ability to rank in search engines, scored 0-100 on a logarithmic scale. Similar metrics exist from other providers: Ahrefs Domain Rating (DR), Majestic Trust Flow, and Semrush Authority Score.
Important: DA/DR are third-party metrics, not Google metrics. Google does not use Domain Authority in its algorithm. However, these metrics correlate with ranking ability because they measure many of the same signals Google considers (backlink quality, diversity, site age).
AiSEO Authority is our composite score that goes beyond backlinks: it combines link profile strength (referring domains, link quality), technical SEO health (Core Web Vitals, mobile-friendliness, security), content signals (E-E-A-T, freshness, depth), and AI readiness (citability, structured data). This provides a more holistic view than backlink-only metrics.
⚡Why It Matters
While not a Google ranking factor itself, Domain Authority strongly correlates with ranking ability. Sites with DA >50 rank for 10x more keywords than sites with DA <20. Understanding your domain's authority level helps set realistic ranking targets and identify the competitive gap.
🔍How AiSEO Checks
AiSEO calculates a composite authority score from available data: Moz DA (when available), backlink profile analysis, technical health score, content quality signals, and AI citability rating.
AiSEO Score Impact
Informational — authority is an output metric reflecting overall site strength, not a single audit check. It's influenced by scores across all categories.
