"How do I increase my Domain Authority?" is one of the most common SEO questions — and one of the most important to answer correctly. DA is not a Google ranking factor, it is a Moz metric, and chasing it as a goal in itself leads to bad decisions. But improving the underlying signals DA measures — your backlink profile quality — genuinely improves rankings. Here is how to do it right.
What actually determines your Domain Authority score?
Moz's Domain Authority algorithm primarily considers:
- The number of unique referring domains linking to your site (more is better)
- The authority of those linking domains (links from high-DA sites carry more weight)
- The quality and relevance of the links
- How your link profile compares to all other sites in Moz's index — DA is a relative score
As covered in our guide to Domain Authority explained, DA is recalculated regularly based on Moz's entire index. Your DA can drop even while you are building good links, simply because other sites in the index grew faster.
What are the most effective legitimate ways to increase Domain Authority?
Broken link building — find broken links on authoritative sites in your niche using our broken link checker, create content that replaces the broken resource, and reach out to offer your page as a replacement. As covered in our guide to safe link building, this tactic has consistently high response rates because you are helping the webmaster fix a real problem.
Original research and data — publish studies, surveys, or data analyses that journalists and bloggers cite as sources. A well-executed data study can earn dozens of links from high-authority publications in a single press cycle, providing a significant DA boost.
HARO and Connectively — earn links from major publications by responding as an expert source to journalist queries. These editorial links from high-DA publications directly improve your DA substantially.
Free tools — tools that solve specific recurring problems earn passive backlinks from resource pages and roundups continuously. Our own broken link checker and speed tool are examples of this approach.
How fast can you realistically increase Domain Authority?
For a new site starting from DA 1–10: reaching DA 20–30 typically takes 6–12 months of consistent, quality link building. For established sites (DA 30–50): each additional DA point becomes harder — it requires increasingly high-authority links to move the needle. A 5-point DA increase for an established site over 12 months is solid progress. "Fast" DA increases of 20+ points in a few months are almost always from purchased links that carry penalty risk.
What are the DA-increasing shortcuts that backfire?
- Buying links — services selling "DA 50+ links" for a fee almost always use link farms or private blog networks. Short-term DA gain with high manual penalty risk.
- Link exchange schemes — reciprocal linking at scale violates Google's guidelines and generates suspicious patterns in anchor text analysis
- Spam directory submissions — submitting to hundreds of low-quality directories generates links that Moz counts but that Google may discount or penalise
