Domain Authority is the single most misunderstood metric in SEO.
Marketers obsess over their DA score. They chase arbitrary number increases. They panic when it drops. And all the while, they miss what domain authority actually means and why it matters for rankings.
Domain Authority is not a Google metric. Google does not publish it. It does not directly affect your rankings on Google’s results pages. But it is a useful predictor of how strongly your website will likely rank, which is why understanding it matters.
This guide explains what domain authority actually is, how it is calculated, what factors genuinely improve it, and which strategies waste time chasing a vanity metric instead of building real ranking authority.
Before diving in, understand that domain authority sits within a broader SEO context. Our guide on what SEO is and why your business needs it gives you the foundation this metric builds on.
What Is Domain Authority?
Domain Authority is a search engine ranking prediction score developed by Moz. It ranges from 0 to 100 and predicts how likely a website is to rank on Google’s search results.
A domain with a DA of 70 will likely rank higher for competitive keywords than a domain with a DA of 30, all other factors being equal. DA is a useful proxy for predicting ranking strength, which is why it is widely referenced in the SEO industry.
Important clarification: Domain Authority is not a Google ranking factor. Google does not use a metric called “Domain Authority.” It is Moz’s proprietary prediction model based on their analysis of Google’s actual ranking signals.
Think of DA as a prediction tool, not a ranking factor itself. A site with high DA is likely to have strong backlinks, good content quality, and technical health, which are actual ranking factors. The DA score itself does not boost your rankings.
How Is Domain Authority Calculated?
Moz calculates DA using machine learning to analyze hundreds of factors, but the primary components are clear:
Backlink profile quality and quantity accounts for the majority of DA. Sites with more backlinks from authoritative sources have higher DA.
Website age and history matters. Newer sites with fresh domains start at lower DA. Established domains with consistent performance build DA faster.
Content quality and relevance influences DA. Sites publishing consistent, high-quality content in a focused niche show stronger authority signals than content farms or thin sites.
Topical authority affects DA. A site that has comprehensive coverage of one topic shows stronger authority in that niche than a generalist site.
Technical SEO health impacts DA indirectly. Fast sites with proper structure, security, and mobile optimization rank better, which builds DA over time.
Brand signals play a role. Branded search volume, direct traffic, and brand mentions across the web signal authority to Moz’s algorithm.
Moz updates DA approximately monthly. You may see your score shift slightly with each update as their algorithm processes new backlink data, content analysis, and ranking signal changes.
Domain Authority vs Other Metrics
Several similar metrics exist. Understanding the differences helps you focus on what actually matters.
| Metric | What It Measures | Source | Google Uses It |
|---|---|---|---|
| Domain Authority (DA) | Predicts ranking strength of entire domain | Moz proprietary metric | No, it is a prediction tool |
| Page Authority (PA) | Predicts ranking strength of individual page | Moz proprietary metric | No, it is a prediction tool |
| Domain Rating (DR) | Similar to DA, based on backlink strength | Ahrefs proprietary metric | No, it is a prediction tool |
| Backlink quantity | Number of sites linking to you | Google monitors this | Yes, actual ranking factor |
| Backlink quality | Authority of linking sites | Google monitors this | Yes, actual ranking factor |
| Content quality | Relevance, depth, originality | Google evaluates directly | Yes, actual ranking factor |
Bottom line: DA is useful for benchmarking against competitors and understanding your relative authority position. But focus on the underlying factors that drive DA, not the score itself.
What Actually Improves Domain Authority
Domain Authority improves when the underlying ranking factors that feed into it improve. Focus on these:
1. Earn high-quality backlinks
Backlinks from authoritative sites with topical relevance pass the most authority. One link from a high-DA site moves your DA more than ten links from low-quality sites.
Our link building strategies guide walks through exactly how to earn these kinds of links through outreach, content, and relationship building.
2. Build topical authority through content
Publishing comprehensive content across related topics signals expertise. Google (and Moz) recognize when a site has deep coverage of one area.
Our content clusters SEO guide shows how to build this kind of topical authority through strategic content architecture.
3. Publish consistent, high-quality content
Sites that publish regular, well-researched content with natural backlink potential build DA faster than those that publish sporadically or produce thin content.
Our how to write SEO blog posts guide covers the exact approach to content creation that earns links and builds authority.
4. Improve E-E-A-T signals
Experience, Expertise, Authoritativeness, and Trustworthiness directly influence how Google (and Moz) evaluate your domain’s authority. Strong E-E-A-T signals correlate with higher DA.
Our E-E-A-T SEO guide explains how to build these signals systematically.
5. Fix technical SEO issues
Sites with poor technical health struggle to earn authority. Fast load times, proper indexation, mobile optimization, and clean architecture all support DA growth.
Our technical SEO audit guide covers the full technical foundation.
How Long Does Domain Authority Take to Build?
Domain Authority does not increase overnight.
A new domain starts at DA 1. Most new sites see minimal movement in their first 3 to 6 months, even with excellent content and linking efforts. It typically takes 12 to 18 months of consistent effort before you see meaningful DA gains.
Realistic DA growth timeline:
Months 0 to 3: Minimal change. Site is too new. Focus on building content foundation and initial links.
Months 3 to 6: Slight increases. If you have earned 10 to 20 quality backlinks and published consistent content, DA may move from 1 to 5-10.
Months 6 to 12: Noticeable growth. Consistent content, growing backlink profile, and improving rankings push DA from 10 to 20-30 range.
Months 12 to 24: Sustained growth. At this stage, DA often increases 20 to 50 points per year depending on backlink quality and content output.
Months 24+: Acceleration. As your authority builds, you rank for more keywords, which generates more natural links, which further builds DA. Growth compounds.
Our how long does SEO take guide covers the full timeline for seeing SEO results, with DA growth as part of that journey.
How to Measure and Monitor Domain Authority
Track your DA progress using these tools:
Moz’s Link Explorer: Enter your domain and get current DA, backlink count, and linking domains. Free tier provides basic data.
Ahrefs: Provides Domain Rating (DR), which is Ahrefs’ equivalent to DA. Many SEOs use DR alongside DA for comparison.
SEMrush: Offers Authority Score, another DA alternative with slightly different methodology.
Google Search Console: While not a DA metric, it shows your actual search performance, which correlates with DA growth.
Rank tracking tools: Monitor your keyword rankings as they improve with DA growth. Rankings are the actual outcome you care about.
Tool: Set up a spreadsheet to track DA monthly. Record the date, DA score, backlink count, and notable events (major content launches, PR placements, etc.). This helps you see which activities correlate with DA gains.
Common Domain Authority Myths
Myth 1: “I need high DA to rank.” False. New sites with DA 5-10 can rank #1 for competitive keywords if the content is better and links are stronger than competitors. DA is predictive, not deterministic.
Myth 2: “DA always increases over time.” False. DA can decrease if you lose backlinks, if backlinks you have decrease in quality, or if competitors build authority faster than you. DA fluctuates monthly.
Myth 3: “I should only take links from high-DA sites.” False. A relevant link from a DA 20 site in your niche is better than a random link from a DA 50 site outside your niche. Relevance matters more than authority.
Myth 4: “Trading or buying links increases DA quickly.” False and risky. Google penalizes link schemes. Buying links may temporarily boost DA but kills rankings when Google detects it. Focus on earning links.
Myth 5: “I need DA 50+ to be successful.” False. Many profitable, successful sites operate at DA 20-30. Page Authority and ranking position matter more than absolute DA.

Why Domain Authority Matters (But Is Not Everything)
Domain Authority is useful because it correlates with actual ranking strength. High-DA sites generally rank better than low-DA sites in competitive spaces.
But DA is a lagging indicator. It measures what you have already built, not what your future rankings will be. You can improve rankings without improving DA (by targeting lower-competition keywords). You can improve DA without improving rankings (by building links for branded searches that generate no traffic).
The goal is not to optimize for DA. The goal is to rank for keywords that drive business value. DA growth is a side effect of doing SEO correctly, not the outcome you are optimizing for.

Frequently Asked Questions
What is a good domain authority score? DA 40+ is considered good authority. DA 20-40 is moderate. DA 1-20 is new or underdeveloped. But relevance and ranking position matter more than absolute DA numbers.
How often does domain authority update? Moz updates DA approximately monthly. Your score may change by a few points with each update as their algorithm processes new data.
Can I improve DA quickly? Not realistically. DA increases slowly over 12 to 24 months with consistent quality work. Anyone promising fast DA gains is likely offering link schemes or other black-hat tactics.
Does domain authority directly affect Google rankings? No. Google does not use a metric called Domain Authority. It is Moz’s proprietary prediction tool. Focus on the actual ranking factors DA predicts: backlinks, content quality, and technical health.
Should I buy links to increase DA? Absolutely not. Buying links violates Google’s guidelines and results in penalties. Focus on earning links through quality content, outreach, and relationship building.
Is domain authority more important than page authority? Not necessarily. Page Authority (for individual pages) is often more relevant for specific keyword rankings. Focus on both domain and page authority through comprehensive strategy.
What is the difference between DA and DR? DA is Moz’s metric. DR (Domain Rating) is Ahrefs’ equivalent. The methodologies are slightly different but both correlate with ranking strength. Use whichever tool you prefer.
How do I check my domain authority? Use Moz’s Link Explorer (free at moz.com), Ahrefs Domain Rating tool, or SEMrush Authority Score. All provide similar data in slightly different formats.
