Domain Authority
DA (Domain Authority)
Moz's 1–100 proprietary score predicting a domain's ability to rank in search results, based primarily on the quality and quantity of inbound backlinks. DA is a relative benchmarking metric useful for comparing sites against competitors — not a signal Google itself uses. Ahrefs Domain Rating (DR) and Semrush Authority Score are equivalent metrics from competing tools.
How Domain Authority works in practice
DA is calculated based on Moz's web crawl data — primarily the number of unique referring domains and the authority of those linking domains, modelled through a logarithmic scale. A new domain starts at DA 1 and can reach DA 30–40 within 12–18 months with consistent link-building; reaching DA 60+ typically takes several years of sustained effort. The most actionable use of DA is competitive benchmarking: identifying the average DA of pages ranking in top 5 for target keywords helps set realistic timelines and link-building targets. Do not conflate DA with Google's ranking signals — a DA 30 page with strong on-page optimisation and search-intent alignment can outrank a DA 70 page that poorly matches query intent.
