Domain rank Moz is a metric — officially called Domain Authority (DA) — developed by Moz to predict how likely a website is to rank in search engine results pages. Understanding and improving this score is one of the most effective ways to benchmark your site’s competitive strength and guide your SEO strategy.

What Is Domain Rank Moz and How Does It Work?
Domain Authority is a logarithmic score on a scale of 1 to 100 — the higher the number, the greater the predicted ranking strength. Because the scale is logarithmic, moving from a DA of 20 to 30 is significantly easier than moving from 70 to 80. Therefore, expectations should be calibrated carefully as your score climbs.
Moz calculates the score using a machine learning model that evaluates the quantity and quality of backlinks pointing to a domain. Specifically, it weighs the number of unique linking root domains, the authority of those domains, and the overall health of the link profile. According to Wikipedia’s overview of domain authority, the metric was first introduced by Moz as a way to approximate Google’s own PageRank signals.
It is important to note that DA is a comparative metric. Rather than measuring an absolute value, it is most useful when comparing your domain against competitors in the same niche. For example, a DA of 35 might be strong in a local services market but weak in a competitive finance vertical.
Why This Score Matters for Your SEO Strategy
Although Google does not use Domain Authority in its ranking algorithm, the metric serves as a useful proxy for backlink health. Sites with high DA scores tend to rank well because they have earned many high-quality links — and those links are exactly what Google’s algorithm rewards.
Additionally, DA is widely used by marketers and publishers to evaluate link-building opportunities. When deciding whether to pursue a guest post or partnership, a site’s DA score provides a quick, standardized benchmark. As a result, improving your own score makes your domain more attractive to potential link partners.
For competitive analysis, DA helps you understand the gap between your site and top-ranking competitors. In practice, if your DA is 30 and your competitor’s is 60, you know a significant link-building investment is required to compete for the same keywords.
How to Check Your Score Using Moz Link Explorer
Checking your DA is straightforward. First, visit Moz Link Explorer and enter your domain URL. The tool will display your current DA score, your Page Authority (PA), the number of linking root domains, and total backlinks. A free account allows a limited number of queries per month, while a paid Moz Pro subscription unlocks deeper data.
When reviewing your results, pay close attention to your linking root domains — this figure is often more meaningful than total backlink count. For instance, 500 links from 10 domains carry less weight than 200 links from 200 unique domains, because diversity signals broader trust across the web.
Regularly auditing your backlink profile in Moz Link Explorer helps you track domain authority progress over time.
5 Steps to Improve Your Moz Domain Authority
Improving your DA requires a consistent, multi-faceted approach. Below is a proven process to follow, whether you are starting from scratch or trying to push past a plateau.
Step 1 — Audit Your Current Backlink Profile
Use Moz Link Explorer to identify all existing backlinks. Look for toxic or spammy links that could be dragging your score down. Moz’s built-in Spam Score feature flags suspicious links automatically, making this process faster.
Step 2 — Remove or Disavow Toxic Links
If you find links from low-quality or irrelevant sites, first attempt to have them removed manually. If that fails, however, submit a disavow file through Google Search Console to signal that those links should be ignored.
Step 3 — Create Link-Worthy Content
Publishing original research, comprehensive guides, and data-driven resources naturally attracts backlinks. In contrast, thin or duplicated content rarely earns editorial links from authoritative sources.
Step 4 — Build Relationships for Editorial Links
Reach out to bloggers, journalists, and industry publishers for guest posting opportunities. Additionally, participating in expert roundups and digital PR campaigns can earn high-value mentions from well-known publications.
Step 5 — Monitor and Iterate Monthly
Track your DA and linking root domains every month. Because Moz updates its index regularly, your score can fluctuate — therefore, consistent monitoring ensures you catch drops early and adjust your strategy accordingly.
Common Mistakes That Hurt Your Score
Many site owners unknowingly damage their DA by focusing on link quantity over quality. For example, purchasing bulk backlinks from link farms may temporarily inflate numbers but ultimately triggers Moz’s spam detection and reduces your score.
Another common mistake is ignoring internal linking. While DA is driven by external backlinks, a strong internal link structure distributes page authority across your site more effectively, which in turn supports better rankings at the page level.
Finally, neglecting lost backlinks is a critical oversight. Sites that previously linked to you may remove or change those links over time. Meanwhile, your competitors keep building. Using Moz Link Explorer’s link tracking features helps you reclaim lost links before the gap widens.
Comparing Domain Authority to Other SEO Metrics
Moz’s DA is one of several third-party authority metrics available to SEOs. Ahrefs offers Domain Rating (DR), and Semrush provides its own Authority Score. Although all three measure backlink strength on a 1-to-100 scale, they use different data sources and algorithms — so scores will differ across tools.
In practice, most SEO professionals track at least two of these metrics to get a more complete picture. Resources like RankAuthority provide practical guidance on interpreting these scores in the context of a broader SEO strategy, helping you prioritize the actions that move the needle most efficiently.
However, no single metric should be treated as the definitive measure of SEO success. Organic traffic, keyword rankings, and conversion rates ultimately matter more than any third-party score. Therefore, use DA as a directional guide rather than a hard target.
Comparing Moz Domain Authority with other SEO authority metrics helps build a more complete picture of your site’s competitive strength.
What Score Should You Be Targeting?
Rather than chasing a fixed number, focus on outranking your direct competitors. If the top three sites in your niche have DA scores of 45, 50, and 55, then targeting a DA of 50 or above is a reasonable goal. Benchmarking against competitors is more actionable than pursuing an arbitrary milestone.
New websites typically begin with a DA near 1. With consistent content creation and targeted link building, reaching a DA of 20 to 30 within the first year is achievable. Reaching 40 to 50, however, generally requires 18 to 24 months of sustained effort and a strong backlink acquisition strategy.
Frequently Asked Questions About Domain Rank Moz
What is domain rank Moz?
Domain rank Moz is Moz’s Domain Authority (DA) score — a 1-to-100 metric that predicts how well a website is likely to rank in search results. It is calculated primarily from the quality and quantity of backlinks pointing to the domain.
What is a good Moz Domain Authority score?
A DA of 40 to 50 is considered average, 50 to 60 is good, and above 60 is strong. New websites start near 1 and grow as they earn quality backlinks over time.
How is Moz Domain Authority calculated?
Moz uses a machine learning model that evaluates linking root domains, total backlinks, and link quality. The score is updated regularly as Moz crawls the web and refreshes its link index.
Does Moz Domain Authority directly affect Google rankings?
No. DA is a third-party metric and is not part of Google’s algorithm. However, because strong backlink profiles drive both DA and organic rankings, improving your DA typically correlates with better search performance.
How long does it take to improve your Moz Domain Authority?
Meaningful DA improvements typically take several months of consistent link-building. Because the scale is logarithmic, gains become progressively harder at higher score ranges, so patience and sustained effort are essential.
What is the difference between Domain Authority and Page Authority?
Domain Authority measures the ranking strength of an entire domain, while Page Authority (PA) measures the ranking strength of a single page. Both use the same 1-to-100 scale and similar calculation methods.
Why did my Moz Domain Authority drop suddenly?
A sudden DA drop is often caused by competitors gaining backlinks faster than you, lost backlinks from your own profile, or Moz updating its algorithm. Spammy links being identified and discounted can also reduce your score.
How can I check my domain rank on Moz?
Visit Moz Link Explorer at moz.com/link-explorer and enter your domain URL. The free version allows limited monthly queries and shows your DA, PA, linking root domains, and top backlinks.
What types of backlinks improve Moz Domain Authority the most?
Backlinks from high-DA, authoritative domains in your niche carry the greatest weight. Editorial links, .edu and .gov domain links, and mentions from well-known publications provide significant authority signals.
Can toxic backlinks lower my Moz Domain Authority?
Yes. A high volume of spammy or low-quality backlinks can negatively affect your DA. Using Moz’s Spam Score feature and disavowing harmful links through Google Search Console helps protect your backlink profile.
Is Moz Domain Authority the same as Ahrefs Domain Rating?
No. They are separate metrics from different tools. Moz uses Domain Authority while Ahrefs uses Domain Rating (DR). Both use a 1-to-100 scale but rely on different algorithms and data sources, so scores often differ significantly.
How many linking root domains do I need to reach a DA of 50?
There is no fixed number, as quality and diversity matter more than raw quantity. However, sites at DA 50 typically have several hundred to a few thousand unique linking root domains from reputable, relevant sources.
Final Thoughts on Building Your Domain Authority
Understanding your domain rank Moz score is an essential part of any competitive SEO strategy. While the metric is not a direct Google ranking factor, it reliably reflects the strength of your backlink profile — and that profile is one of the most powerful signals in organic search. By auditing your links, removing toxic ones, creating genuinely valuable content, and building relationships that earn editorial mentions, you can steadily grow your DA and improve your site’s long-term search visibility. For additional strategic guidance, RankAuthority offers actionable resources to help you build authority at every stage of your SEO journey.
