What is Domain Authority (DA)?
Domain Authority is a 0-100 search-engine ranking score developed by Moz. It predicts how well a website will rank on Google's search results pages, calculated from the quality and quantity of inbound backlinks. Higher DA = better SEO authority. A DA above 50 is excellent for most niches.
How to improve your Domain Authority
Three reliable levers: (1) earn high-quality backlinks from authoritative sites in your niche, (2) publish in-depth long-form content that other sites want to cite, (3) prune low-quality / spammy backlinks via Google's Disavow Tool. DA updates monthly — patience compounds.
