Domain Authority
What is Domain Authority?
Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine result pages (SERPs). It ranges from 1 to 100, with higher scores indicating a greater ability to rank.
Synonyms: DA, Website Authority, Site Authority, Domain Rating

Why Domain Authority is Important
Domain Authority plays a crucial role in growth hacking strategies focused on improving search engine visibility. A higher Domain Authority score suggests that a website has a better chance of ranking well in search results, potentially driving more organic traffic. This metric helps marketers and SEO professionals gauge the overall strength of a website's backlink profile and its potential to compete in search rankings.
How Domain Authority is Calculated
Domain Authority is calculated using multiple factors, including:
- Number of linking root domains
- Total number of backlinks
- MozRank
- MozTrust
These factors are combined into a single score using a logarithmic scale, making it harder to increase Domain Authority as the score gets higher.

- Create high-quality, linkable content
- Build a strong backlink profile from reputable websites
- Improve your internal linking structure
- Enhance your website's technical SEO
- Be patient, as Domain Authority takes time to increase
