Introduction
In 2025, Domain Authority (DA) remains one of the most discussed metrics in the world of SEO. While Google does not officially use Domain Authority as a ranking factor, this Moz-created metric still plays a huge role in how SEOs, bloggers, and digital marketers gauge a website’s ability to rank.
If you’re new to blogging or working toward Google AdSense approval, understanding Domain Authority and how to improve it can give you a powerful edge.
In this guide, we’ll explore:
- What Domain Authority actually means
- Why it matters in SEO strategy
- How it influences your blog rankings
- Proven ways to increase your DA in 2025
Chapter 1: What is Domain Authority (DA)?
✅ Defined by Moz:
Domain Authority is a score between 1–100 that predicts how well a website will rank on search engines. The higher the score, the stronger the site’s authority.
✅ How It’s Calculated:
Moz calculates DA based on:
- Number and quality of backlinks
- Linking root domains
- Website structure and technical performance
- Moz’s machine learning algorithm
✅ Difference Between DA & PA:
- Domain Authority = Overall domain power (yourdomain.com)
- Page Authority = Ranking strength of a single page (yourdomain.com/your-post)
Chapter 2: Is Domain Authority a Google Ranking Factor?
Short answer: No.
But:
- Websites with high DA usually rank better because they have strong backlinks, good content, and solid site structure.
- Google does consider E-E-A-T, backlinks, and trust—all factors that correlate with a higher DA.
Conclusion: Google doesn’t use DA directly, but improving your DA can help your SEO indirectly.
