What Is Domain Authority?
Domain Authority (DA) is a metric created by Moz that estimates the ranking strength of an entire domain on a 1-100 logarithmic scale. A higher DA indicates a greater likelihood of ranking well. Similar metrics include Ahrefs' Domain Rating (DR) and Semrush's Authority Score. Note that DA is not a Google ranking factor — it's a third-party predictive metric.
Why Domain Authority Matters
DA is useful for competitive analysis — comparing your site's relative strength against competitors. It helps evaluate link building opportunities (links from high-DA sites are generally more valuable). DA is also useful for tracking your site's overall authority growth over time. A new site typically starts at DA 1 and grows as it acquires quality backlinks.
How to Improve Domain Authority
Earn high-quality backlinks from authoritative, relevant websites. Create link-worthy content (original research, comprehensive guides, tools). Remove or disavow toxic spam links. Improve internal linking structure. Build topical authority by covering subjects deeply. DA improvement is gradual — focus on long-term link acquisition rather than quick wins.
